Attorney Docket No.1723.2.WO2 PATENT APPARATUS, SYSTEMS AND METHODS FOR INCREASING PLANT PRODUCTIVITY USING A FUNGAL MICROBIOME CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to International Application No. PCT / US2024 / 036393, filed July 1, 2024, entitled METHODS, SYSTEMS AND RELATED MACHINE LEARNING TOOLS FOR ACCELERATED PLANT PRODUCTIVITY AND ATMOSPHERIC CARBON SEQUESTRATION, and claims priority to U.S. Provisional Application Serial No. 63 / 571,140, filed March 28, 2024, entitled “METHODS, SYSTEMS AND RELATED MACHINE LEARNING TOOLS FOR ACCELERATED PLANT PRODUCTIVITY AND ATMOSPHERIC CARBON SEQUESTRATION,” the disclosures of which are incorporated herein by reference in their entirety. BACKGROUND OF THE INVENTION Field of the Disclosure

[0002] This application relates generally to improved apparatus, methods and systems for selecting a soil microbiome for increasing plant productivity and / or accelerating plant biomass growth and / or plant-mediated sequestration of atmospheric carbon, in particular, for automating selection of microbial drivers thereof. Background

[0003] Commercial applications for soil microbiome melioration have been slow to develop, particularly in scenarios where harnessing the benefits of an entire native community is sought. Several factors contribute to this slow development, such as uncertain methods for identifying the appropriate microbial biodiversity, and due to difficulties in scaling inoculum production and fungal establishment.

[0004] The vast majority of plant species form symbioses with fungi, which significantly influence their access to growth-limiting resources. Recent research has shown, however, that functional characteristics of the soil fungal microbiome as a whole can influence the growth of an entire forest. For example, there is a strong correlation between the fungal microbiome’s functional characteristics and overall forest productivity. Thus, soil fungal biodiversity servesAttorney Docket No.1723.2.WO2 PATENT as a strong bio-indicator of underlying plant growth and health. Additionally, recent research has shown that certain location-specific fungal species are linked to forest performance, measured in terms of tree growth rate and ability to sequester atmospheric carbon.

[0005] Therefore, it is critical to take a holistic and natural approach in developing systems and methods of forest management and regeneration, especially in commercial contexts where biomass productivity is tightly linked to economic profitability. While commercial microbial inoculants are widely available, cross-laboratory studies have shown that many fungal inoculant products are ineffective at increasing tree growth rate, biomass productivity and atmospheric carbon uptake, especially in the long-term. Most commercial inoculants are ineffective for several reasons, most notably due to the limited number of species they contain, most of which can be ill-suited for geographically wide-spread inoculation across a variety of ecological regions.

[0033] Unless the context indicates otherwise, it is specifically intended that the various features of the invention described herein can be used in any combination. Moreover, the present invention also contemplates that in some embodiments of the invention, any feature or combination of features set forth herein can be excluded or omitted. To illustrate, if the specification states that a composition comprises components A, B and C, it is specifically intended that any of A, B or C, or a combination thereof, can be omitted and disclaimed singularly or in any combination.

[0034] As used in the description of the invention and the appended claims, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0035] Also as used herein, “and / or” refers to and encompasses any and all possible combinations of one or more of the associated listed items, as well as the lack of combinations when interpreted in the alternative (“or”).

[0036] The term “about,” as used herein when referring to a measurable value such as an amount or concentration and the like, is meant to encompass variations of ± 10%, ± 5%, ± 1%, ± 0.5%, or even ± 0.1% of the specified value as well as the specified value. For example, “about X” where X is the measurable value, is meant to include X as well as variations of ± 10%, ± 5%, ± 1%, ± 0.5%, or even ± 0.1% of X. A range provided herein for a measurable value may include any other range and / or individual value therein.

[0037] As used herein, phrases such as “between X and Y” and “between about X and Y” should be interpreted to include X and Y. As used herein, phrases such as “between about X and Y” mean “between about X and about Y” and phrases such as “from about X to Y” mean “from about X to about Y.”

[0038] Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as ifAttorney Docket No.1723.2.WO2 PATENT it were individually recited herein. For example, if the range 10 to 15 is disclosed, then 11, 12, 13, and 14 are also disclosed.

[0039] The term “comprise,” “comprises” and “comprising” as used herein, specify the presence of the stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0040] As used herein, the transitional phrase “consisting essentially of” means that the scope of a claim is to be interpreted to encompass the specified materials or steps recited in the claim and those that do not materially affect the basic and novel characteristic(s) of the claimed invention. Thus, the term “consisting essentially of” when used in a claim of this invention is not intended to be interpreted to be equivalent to “comprising.”

[0041] As used herein, the terms “increase,” “increasing,” “enhance,” “enhancing,” “improve” and “improving” (and grammatical variations thereof) describe an elevation of at least about 25%, 50%, 75%, 100%, 150%, 200%, 300%, 400%, 500% or more as compared to a control.

[0042] As used herein, the terms “reduce,” “reduced,” “reducing,” “reduction,” “diminish,” and “decrease” (and grammatical variations thereof), describe, for example, a decrease of at least about 5%, 10%, 15%, 20%, 25%, 35%, 50%, 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100% as compared to a control. In some embodiments, the reduction can result in no or essentially no (i.e., an insignificant amount, e.g., less than about 10% or even 5%) detectable activity or amount.

[0043] As used herein, “plant productivity” refers to the rate at which plants in an ecosystem synthesize organic matter through photosynthesis. For example, plant productivity can refer to the rate of biomass increase of a plant and / or the rate of atmospheric carbon sequestration by a plant. In some embodiments, plant productivity can be measured at the level of an individual plant, a plurality of plants, a whole ecosystem (e.g., a forest), and other like groupings of plants of the same or different species. In some embodiments, plant productivity can be quantified as the amount of carbon fixed per unit area per period of time, which can be expressed in terms of mass (e.g., grams of carbon per square meter per year). In some embodiments, plant productivity can be divided into subcategories, including, but not limited to, (1) gross primary productivity (GPP), which is the total rate of photosynthesis inclusive ofAttorney Docket No.1723.2.WO2 PATENT oxygen produced and carbon dioxide consumed by photosynthesis, and (2) net primary productivity (NPP), which is carbon dioxide respired by a plant or group of plants subtracted from the GPP. In some embodiments, NPP can represent the rate of new biomass production available for consumption by heterotrophic organisms (such as animals, fungi, and bacteria) or for accumulation in the form of standing biomass. In some embodiments, plant productivity can be further quantified in terms of biomass accumulation, leaf area index (LAI), growth rate, plant height, yield, net assimilation rate, water use efficiency, nutrient use efficiency, and photosynthesis rate.

[0044] As used herein, “carbon sequestration” refers to the process of capturing and storing atmospheric carbon dioxide (CO2) in a stable form. For example, carbon sequestration can be achieved through physical, chemical, or biological processes that remove CO2 from the atmosphere and secure it in natural (e.g., forests) or artificial reservoirs.

[0045] In some embodiments, carbon sequestration can occur through photosynthesis of plants and other photosynthesizing organisms. As used herein, carbon sequestration can refer to the biological conversion of atmospheric CO2into organic carbon compounds and biomass through the process of photosynthesis. In some embodiments, plant photosynthesis can include a process whereby plants utilize specialized enzymes to catalyze the fixation of CO2into organic molecules (e.g., glucose, cellulose, lignin, etc.). In some embodiments, plant photosynthesis can be an effective means of transferring carbon from the atmosphere and stably storing it in living tissue. Advantageously, the stored organic material can contribute to nutrient cycling in ecosystem, for example, when plants die and decompose, sequestered atmospheric carbon can be transferred and recycled in non-gaseous form through carbon pools. In some embodiments, carbon sequestration by natural ecosystems can be a means of mitigating anthropogenically driven levels of CO2in the atmosphere that, e.g., can contribute to climate change. In some embodiments, carbon sequestration by plants can be enhanced by selecting plant species with high growth rates and long lifespans and through managing forests for increased density and longevity.

[0046] As used herein, “growth-promoting fungal consortium” refers to a pool of fungal species and / or strains that increase the plant productivity of an individual plant, and ecosystem, or any subset therebetween. In some embodiments, a growth-promoting fungal consortium refers to a subset of a fungal microbiome. For example, a fungal microbiome can includeAttorney Docket No.1723.2.WO2 PATENT pathogenic, parasitic, commensal species, in addition to mutualistic species, wherein pathogenic and / or commensal species may not be species best suited to accelerate plant growth and / or increase atmospheric carbon sequestration.

[0047] As used herein, “geographic location” refers to any location, point or area that can be defined by latitudinal and longitudinal coordinates. In some embodiments, the geographic location is a natural ecosystem. For example, a natural ecosystem can be an old growth forest, a native grassland, a rainforest, or any other ecosystem that has not been substantially affected by human activities. In some alternative embodiments, a geographic location can be a location involving substantial human activities. For example, farmlands, orchards, gardens, plantations and other locations where plants grow as the direct result of human activities. As used herein, “geographically distinct,” refers to a location or area that is separate from other locations or areas based on physical, political, ecological, spatial, or like boundaries.

[0048] As used herein, “nucleic acid material” refers to a polymeric form of nucleotides of any length, either ribonucleotides or deoxyribonucleotides. Thus, these terms include single-, double-, or multi-stranded DNA or RNA. Examples of polynucleotides include a gene or gene fragment, whole genomic DNA, genomic DNA, epigenomic, genomic DNA fragment, exon, intron, messenger RNA (mRNA), regulatory RNA, transfer RNA, ribosomal RNA, non-coding RNA (ncRNA) such as PIWI-interacting RNA (piRNA), small interfering RNA (siRNA), and long non-coding RNA (lncRNA), small hairpin (shRNA), small nuclear RNA (snRNA), micro RNA (miRNA), small nucleolar RNA (snoRNA) and viral RNA, ribozyme, cDNA, recombinant polynucleotide, branched polynucleotide, plasmid, vector, isolated DNA of any sequence, isolated RNA of any sequence, nucleic acid probe, primer or amplified copy of any of the foregoing. A polynucleotide can include modified nucleotides, such as methylated nucleotides and nucleotide analogs including nucleotides with non-natural bases, nucleotides with modified natural bases such as aza- or deaza-purines. A polynucleotide can be composed of a specific sequence of four nucleotide bases: adenine (A); cytosine (C); guanine (G); and thymine (T). Uracil (U) can also be present, for example, as a natural replacement for thymine when the polynucleotide is RNA. Uracil can also be used in DNA. The term “nucleic acid sequence” can refer to the alphabetical representation of a polynucleotide or any nucleic acid molecule, including natural and non-natural bases.Attorney Docket No.1723.2.WO2 PATENT

For example, the forest bioreactor can include a feedstock and / or a plurality of conditions favoring the growth of fungal species and / or strains comprising a soil microbiome. In some embodiments, the bioreactor can be configured such as to suppress growth of undesirable species (e.g., contaminant organisms) present in a sample, such as species that do not include a growth-promoting fungal consortium.

[0051] As used herein, “feedstock” refers to a material or surface thereof, from or on which an organism lives, grows, and / or obtains nourishment. In some embodiments, a substrate provides sufficient nutrition to the organism under target growth conditions such that the organism can live and grow without providing the organism a further source of nutrients.

Using a different set of training hyperparameters to train two machine learning models that have the same architecture (i.e., the same structural hyperparameters) and using the same training data may result in the parameters of the first machine learning model differing from the parameters of the second machine learning model. Despite having the same architecture and having been trained using the same training data, a machine learning model may generate different outputs from each other given the same input data. Accordingly, accuracy, precision, recall, and / or bias may vary between machine learning models.

[0066] In some embodiments, training hyperparameter(s) may include a train-test split ratio, activation function and / or activation function type (e.g., in examples like Kolmogorov- Arnold networks (KANs) where the activation function type can be determined as part of training from an available set of activation functions and / or limits on the activation function parameters specified by the training hyperparameters), training stage(s) (e.g., using a first set of hyperparameters for a first epoch of training, a second set of hyperparameters for a second epoch of training), a batch size and / or number of batches of data in a training epoch, a number of epochs of training, the loss function used (e.g., L1, L2, Huber, Cauchy, cross entropy), the component(s) of the machine learning model that are altered using the loss for a particular batch or during a particular epoch of training (e.g., some components may be “frozen,” meaning their parameters are not altered based on the loss), learning rate, learning rate optimization algorithm type (e.g., gradient descent, adaptive, stochastic, etc.) used to determine an alteration to one or more parameters of one or more components of the machine learning model to reduce the loss determined by the loss function, learning rate scheduling, and / or the like.

[0076] As used herein, a “linear model” refers to a mathematical model that describes the relationship between a dependent variable and one or more independent variables using a linear function. In some embodiments, changes in independent variables correspond to proportional changes in a dependent variable, e.g., as determined by a set of coefficients. A linear model may include an intercept term and an error component to account for variations not explained by independent variables. A linear model may be used for predictive modeling, statistical inference, classification, or optimization and may be implemented in various computational or analytical frameworks. A linear model may include, for example, but not limited to, linear regression, multiple linear regression, generalized linear model (GLM), logistic regression, Poisson regression, linear discriminant analysis (LDA), linear mixed model (LMM), hierarchical linear model, ridge regression, lasso regression, elastic net regression, principal component regression (PCR), partial least squares regression (PLS), autoregressive integrated moving average (ARIMA) with linear components, ordinary least squares (OLS) regression, and the like. Parameters of a model may be determined through methods including, but not limited to, least squares estimation, maximum likelihood estimation, Bayesian inference, and the like. In some implementations, a linear model may be applied to structured or unstructured data, make predictions, or optimize decision-making processes.

[0077] A linear model may include a generalized linear model. As used herein, a “generalized linear model” or “GLM” refers to a statistical modeling framework that extends linear regression by allowing a dependent variable to follow a probability distribution from the exponential family, such as, e.g., the normal, binomial, Poisson, or gamma distribution. A GLM may model the relationship between one or more independent variables and a dependent variable through a linear predictor function, which applies a transformation known as a link function to map the linear combination of independent variables to the expected value of a dependent variable. Parameters of a GLM may be estimated using techniques such as maximum likelihood estimation or iteratively reweighted least squares (IRLS). A GLM may be applied in computational and statistical environments for tasks including, but not limited to, predictive modeling, classification, risk assessment, and decision support systems. ExamplesAttorney Docket No.1723.2.WO2 PATENT of GLMs include, but are not limited to, logistic regression, Poisson regression, gamma regression, and the like, each of which may apply a different link function and probability distribution depending on the nature of the dependent variable.

[0078] As used herein, a “generalized linear mixed model” or “GLMM” refers to an extension of a GLM that incorporates both fixed effects and random effects, allowing for modeling of data with hierarchical, grouped, or correlated structures. A GLMM may accommodate response variables following distributions from an exponential family (e.g., normal, binomial, Poisson, etc.) while accounting for variability across different levels of a dataset through random effects. A GLMM may be applied in computational and statistical environments for predictive modeling, hierarchical data analysis, and repeated-measures data. Parameter estimation in a GLMM may be performed using maximum likelihood estimation, restricted maximum likelihood (REML), or Bayesian inference methods.

[0079] As used herein, “effect size” refers to a quantitative measure of the magnitude of a relationship or difference between variables in a statistical model. Effect size may provide a standardized metric for assessing the strength of an association, the impact of an independent variable on a dependent variable, or the practical significance of a statistical finding. Effect size measures may be absolute (e.g., mean differences, regression coefficients) or standardized (e.g., Cohen’s d, Pearson’s r, odds ratios) and may be computed using various statistical methods depending on the model type and data structure. In the context of a linear model (LM), effect size may refer to the estimated regression coefficients, which represent the expected change in a dependent variable for a one-unit change in an independent variable, assuming all other variables remain constant. Standardized effect sizes, such as beta coefficients (standardized regression coefficients) or Cohen’s f2, may also be used to compare the relative importance of predictors across different scales. In the context of a GLM, effect size refers to estimated model coefficients transformed according to a GLM’s link function to provide interpretable effect measures as would be readily understood by the ordinarily skilled artisan in the relevant art. In the context of a GLMM, effect size includes measures for both fixed effects and random effects. For example, fixed effects can follow the same principles as GLMs, using untransformed or transformed coefficients (e.g., odds ratios, rate ratios) to quantify predictor impact, and random effects can be assessed using variance components, intraclassAttorney Docket No.1723.2.WO2 PATENT correlation coefficients (ICCs), or variance explained by random factors to measure a contribution of hierarchical grouping structures.

[0080] As used herein, “cumulative growth effect size” refers to a quantitative measure of the aggregated impact of one or more independent variables on growth-related outcomes of a plant over a defined period or across multiple experimental conditions. A cumulative growth effect size may account for the combined or sequential influence of predictors on cumulative growth, incorporating both direct and indirect contributions to changes in a dependent variable associated with growth, such as biomass accumulation, height expansion, or productivity increases. Cumulative growth effect size(s) may be computed using statistical models, including, but not limited to, linear models, GLMs, GLMMs, and the like, by estimating a combined effect of predictor variables over time or across experimental treatments. The effect size may be expressed in absolute terms (e.g., total biomass increase per unit predictor change) or standardized terms (e.g., relative effect size compared to baseline conditions). In the context of hierarchical or multilevel data structures, cumulative growth effect size may also include variance components, interaction effects, or aggregated marginal effects to assess overall contribution to growth dynamics.

[0081] As used herein, a “distance-based multivariate model” refers to a statistical modeling framework for analyzing relationships among multiple dependent variables using a distance or dissimilarity matrix rather than direct numerical measurements of individual observations. Such models are configured to assess patterns, differences, or relationships between data points based on predefined distance metrics, including but not limited to Euclidean distance, Bray-Curtis dissimilarity, Jaccard similarity, Mahalanobis distance, and the like. In some embodiments, distance-based multivariate models may employ permutation- based hypothesis testing, eigenvalue decomposition, constrained ordination, or regression-like techniques to quantify variations among predefined groups or explain variations in multivariate data using predictor variables. Examples of distance-based multivariate models include, but are not limited to, Permutational Multivariate Analysis of Variance (PERMANOVA), Analysis of Similarities (ANOSIM), Mantel tests, and Distance-Based Redundancy Analysis (db-RDA), and the like.

[0082] As used herein, a “weighted rank model” refers to a computational framework that ranks a set of items or entities based on multiple input scores, wherein each input score isAttorney Docket No.1723.2.WO2 PATENT assigned a predefined or dynamically calculated weight to determine its relative contribution to the final ranking. In some embodiments, a weighted rank model may process input data from one or more predictive or statistical models, normalize the input scores as needed, apply weighting factors to each score, and compute a combined weighted score for each ranked entity. In some embodiments, weighting factors may be predetermined, adaptively learned, or optimized using statistical or machine learning techniques, including, but not limited to, Bayesian optimization, gradient-based learning, or heuristic ranking adjustments. A weighted rank model may be implemented in various computational applications, including predictive analytics, decision support systems, recommendation engines, multi-criteria optimization frameworks, and the like. Examples of weighted rank models include, but are not limited to, multi-model ensemble ranking systems, machine-learning-driven ranking frameworks, and statistical ranking algorithms that incorporate heterogeneous data sources. A weighted rank model may operate on structured or unstructured data and may support real-time or batch processing implementations.

[0089] In some embodiments, microbiome diversity may include quantitative and qualitative measures of taxonomic, functional, and phylogenetic variation within and between microbial communities. Ecological diversity may be assessed using alpha diversity (e.g., within-sample diversity) and beta diversity (e.g., between-sample dissimilarity), which may be computed based on species richness, abundance distributions, and phylogenetic relationships. Diversity may be calculated using methods such as species accumulation curves, rarefaction analysis, Hill numbers, and ordination techniques, which quantify the distribution and heterogeneity of microbial taxa across environmental gradients. Additionally, microbiome diversity metrics may be derived from OTU-based, ASV-based, metabarcode or metagenome sequence data to capture taxonomic and functional variability. Alpha diversity metrics may include species richness, Shannon Diversity Index (H’), Simpson’s Diversity Index (D), Chao1 Index, Faith’s Phylogenetic Diversity (PD), and / or other like indices.

It will be appreciated by the ordinarily skilled artisan in the relevant art that a functional characteristic may include any measurable biological, ecological, and biochemical traits of an organism that define its role within an ecosystem, its metabolic capabilities, and / or its interactions with other organisms and the environment.

[0092] In some embodiments, location-specific plant productivity data may comprise plant height, plant diameter, plant biomass, plant survival, age of the geographically distinct plant community, plant density, and the like, collected from each of the geographically distinct plant communities. Plant height and plant diameter measurements may be recorded at predeterminedAttorney Docket No.1723.2.WO2 PATENT time intervals to assess growth trajectories and structural development. Plant biomass may be estimated through direct sampling, allometric equations, or remote sensing techniques, e.g., to provide information on aboveground and belowground nutrient allocation. Plant survival may be monitored to evaluate establishment success, resilience to environmental stressors, and long-term viability within different geographic regions. Age of the geographically distinct plant community may be determined based on stand history, dendrochronology, remote sensing-derived forest succession data, and the like, e.g., to determine factors influencing plant growth potential and ecological interactions. Plant density may be measured as the number of individuals per unit area, and may provide information on competitive interactions, resource availability, and community structure. Additional plant productivity metrics may include leaf area index (LAI), specific leaf area (SLA), chlorophyll content, net assimilation rate, transpiration rate, and canopy closure, which are indicative of photosynthetic efficiency, water- use strategies, and overall plant health. Environmental variables influencing productivity, such as soil nutrient content, microbial associations, precipitation levels, temperature, and light availability, may also be incorporated to refine growth predictions. These data alone or in combination may enable a quantitative assessment of plant performance across multiple geographically distinct plant communities, and may support comparative growth analyses, predictive modeling, and optimization of site-specific plant productivity strategies.

[0093] In some embodiments, location-specific environmental covariate data may comprise soil composition, contemporary climate data, future climate projection data, and the like, e.g., collected from geographically distinct plant communities. For example, location- specific environmental covariate data can serve as input for modeling plant productivity, microbial community dynamics, and ecosystem resilience across diverse landscapes. Soil composition may include physical, chemical, and biological properties that influence plant and microbial interactions. Physical properties may include soil texture (e.g., per cent sand, silt, and clay), bulk density, porosity, water-holding capacity, and the like, which may affect root penetration and water availability. Chemical properties may encompass pH, organic matter content, cation exchange capacity (CEC), concentration of essential macronutrients (e.g., nitrogen, phosphorus, potassium) and micronutrients (e.g., calcium, magnesium, sulfur, iron, and zinc), and the like. Biological properties may include microbial biomass, enzymaticAttorney Docket No.1723.2.WO2 PATENT activity, mycorrhizal colonization rates, presence of beneficial or pathogenic microbial taxa, and the like.

[0094] Contemporary climate data may include temperature, precipitation, humidity, solar radiation, wind speed, atmospheric CO2 concentration, and the like, e.g., collected through on- site meteorological stations, remote sensing platforms, or climate monitoring databases. Contemporary climate data may provide real-time insights into weather patterns, microclimatic variability, and seasonality effects that impact plant growth and microbial processes.

[0095] Future climate projection data may be derived from global climate models (GCMs), regional climate downscaling techniques, probabilistic climate scenario analyses, and the like, e.g., enabling the assessment of long-term trends in temperature shifts, precipitation variability, extreme weather events, and climate-induced stressors. Future climate projection data may enable predictions of ecosystem resilience, plant community shifts, microbial adaptation strategies under changing climatic conditions, and the like. Additional environmental covariates may include elevation, slope, aspect, hydrological features (e.g., water table depth, drainage capacity), vegetation cover, land-use history, disturbance regimes (e.g., fire frequency, logging, or agricultural conversion), and the like, which, e.g., may influence site productivity, species composition, and habitat suitability for soil microbiomes.

[0096] According to some embodiments of the present invention, an apparatus for selecting a soil microbiome having increasing plant productivity may include operations including, using the machine learning model, determining a plant biomass prediction comprising an estimate of plant height, plant diameter, and plant allometries at a geographically referenced site. A machine learning model may be configured to be either a supervised machine learning model or an unsupervised machine learning model. In some embodiments, a supervised machine learning model may be used, e.g., wherein the model is trained on labeled datasets containing known relationships between soil microbiome characteristics, plant productivity metrics, and environmental covariates. In some embodiments, a supervised learning model may be employed to predict biomass based on environmental and biological variables. A supervised machine learning model may be implemented as a boosted regression tree model configured to utilize spatially explicit environmental covariates, biodiversity indexes, and forest productivity data as input features. A supervised machine learning model may be trained at the individual tree level, incorporatingAttorney Docket No.1723.2.WO2 PATENT measurements such as tree height, tree diameter, and species-specific allometric equations to estimate biomass. In some embodiments, a supervised learning model may be optimized using cross-validation techniques, such as k-fold cross-validation, to improve generalization and predictive accuracy. In some embodiments, a k-fold cross-validation may include a 5-fold cross-validation, 10-fold cross-validation, leave-one-out cross-validation (LOO-CV), 3-fold cross-validation, 7-fold cross-validation, 2-fold cross-validation (holdout validation), or the like. A supervised machine learning model may be trained using automated hyperparameter tuning frameworks, e.g., using an algorithm (such as but not limited to the hyperparameter optimization framework) to iteratively refine performance based on predefined optimization metrics. For example, a boosted regression tree model may be trained using a dataset comprising tree-level measurements from geographically distinct forest plots, where tree height, tree diameter, soil nutrient levels, and microbial diversity indices serve as predictive features. By way of further example, the model may be validated using 5-fold cross-validation, ensuring robustness across different environmental conditions. By way of further example, through iterative optimization, the model may refine its ability to predict biomass and inform forestry management strategies by identifying factors contributing to high-productivity forest ecosystems.

[0097] In some embodiments, an apparatus for predicting tree biomass and forest growth may employ a supervised learning model to generate biomass, height, and diameter predictions for trees at geographically referenced sites. A supervised learning model may utilize environmental covariates, soil microbiome data, and climate variables to estimate tree growth patterns across a spatially defined region. Predictions may be made at individual site levels or aggregated across larger geographical areas for broader assessments of forest productivity. For example, a supervised machine learning model may be applied to predict tree growth metrics across a geographic area. A supervised learning model may generate site-specific estimates of tree height, diameter, and biomass accumulation based on environmental conditions such as soil composition, precipitation, temperature, elevation, and microbial diversity indices. For example, a supervised learning model may predict forest biomass accumulation across a geographic area with outputs averaged over the entire area to provide a broad-scale assessment of carbon sequestration potential and forest yield. By way of further example, a supervised machine learning model can generate localized predictions within a 100-mile radiusAttorney Docket No.1723.2.WO2 PATENT surrounding carbon project locations, enabling targeted assessments of tree growth in reforestation sites, allowing for precision forestry applications, such as carbon credit validation, optimized planting strategies, and site selection for afforestation projects.

[0098] In some embodiments, an unsupervised machine learning model may be employed to identify patterns, clusters, or latent structures within the dataset without requiring predefined labels. An unsupervised model may apply techniques such as principal component analysis (PCA), k-means clustering, hierarchical clustering, autoencoders, and the like, to group soil microbiomes with similar ecological functions or to detect underlying microbial community structures associated with plant growth.

[0099] In some embodiments, a hybrid approach incorporating both a supervised and an unsupervised machine learning model may be implemented. For example, an unsupervised clustering algorithm may first identify microbiome groupings, and a supervised model may then be trained to predict the impact of each microbiome cluster on plant growth.

[0100] In some embodiments, plant allometry may include quantitative relationships between plant structural traits and overall biomass, growth dynamics, or resource allocation patterns. Plant allometric measurements may be used to estimate biomass accumulation, carbon storage potential, and ecological fitness across different environments. For example, plant allometry may include height-to-diameter ratios, which describe structural stability and growth form, and allometric scaling equations, which predict total biomass based on measured dimensions. Additional allometric traits may include leaf area-to-stem diameter ratios, root-to- shoot biomass ratios, and crown volume estimations, which provide insights into photosynthetic capacity, nutrient allocation, and drought resilience. These relationships may be determined through empirical field measurements, remote sensing techniques, or predictive modeling frameworks to assess plant productivity in forestry, agriculture, and ecological restoration applications.

[0101] According to some embodiments of the present invention, an apparatus for selecting a soil microbiome having increasing plant productivity may include operations including receiving experimental data comprising (i) productivity responses of plants grown ex situ relative to the particular geographically distinct plant community, wherein each plant is inoculated with an individual soil sample harvested from a particular geographically distinct plant community such that each plant is inoculated with a different soil sample, and (ii) fungalAttorney Docket No.1723.2.WO2 PATENT biodiversity data associated with each plant at predetermined times during plant growth. An apparatus according to any embodiment disclosed herein may be configured to receive, process, and analyze experimental data, enabling data-driven selection of soil microbiomes associated with increased plant productivity.

[0102] In some embodiments, experimental data may comprise productivity responses of plants grown ex situ relative to a particular geographically distinct plant community, wherein each plant may be inoculated with an individual soil sample harvested from a specific geographically distinct plant community, e.g., ensuring that each plant is exposed to a unique soil microbiome. For example, seedlings may be grown in controlled nursery conditions where soil samples originating from old-growth forests, regenerating forests, or agricultural lands are applied to assess their respective influences on plant biomass accumulation, root development, and survival rates.

[0103] In some embodiments, productivity responses may comprise: plant height, plant root collar diameter, plant rate of height change, biomass accumulation, leaf area index (LAI), growth rate, net assimilation rate, water use efficiency, nutrient use efficiency, and photosynthesis rate and / or plant cone volume collected from the plants grown ex situ relative to the particular geographically distinct plant community.

[0104] In some embodiments, experimental data may comprise fungal biodiversity data associated with each plant at predetermined times during plant growth, wherein fungal community structure and dynamics may be monitored using nucleic acid sequencing (e.g., high-throughput sequencing of eDNA), DNA metabarcoding, quantitative PCR techniques, and the like. For example, fungal biodiversity can be assessed at early-stage root colonization, mid-growth, and at full plant maturity to determine how microbial composition shifts over time and how different fungal taxa correlate with plant productivity metrics such as height, stem diameter, and biomass allocation. For example, fungal biodiversity can be measured using high-throughput DNA sequencing, such as amplicon sequencing of ITS or 18S rRNA genes from environmental samples, and sequences can be clustered into OTUs or ASVs, with diversity metrics (e.g., Shannon Index, Bray-Curtis dissimilarity) computed to assess taxonomic richness and community composition. For example, fungal biodiversity can be assessed through functional profiling, including enzyme activity assays, metabolite analysis,Attorney Docket No.1723.2.WO2 PATENT or metatranscriptomics to quantify biochemical functions such as lignocellulose degradation, organic acid secretion, and nutrient cycling.

[0105] In some embodiments, fungal biodiversity data associated with each plant may be collected at predetermined times during plant growth. In some embodiments, predetermined times may include a 1-week interval, 2-week interval (biweekly), 3-week interval, 4-week interval (monthly), 6-week interval, 8-week interval (bimonthly), 10-week interval, 12-week interval (quarterly), 16-week interval, 20-week interval, 24-week interval (semiannual), 36- week interval, 48-week interval, 1-year interval (annual). In some embodiments, the predetermined times may include from a 1-week interval to a 3-week interval, from a 2-week interval to a 6-week interval, from a 3-week interval to an 8-week interval, from a 4-week interval to a 10-week interval, from a 6-week interval to a 12-week interval, from an 8-week interval to a 16-week interval, from a 10-week interval to a 20-week interval, from a 12-week interval to a 24-week interval, from a 16-week interval to a 36-week interval, from a 20-week interval to a 48-week interval, from a 24-week interval to a 1-year interval. In some embodiments, the predetermined times are from weekly to annually.

[0106] According to some embodiments of the present invention, an apparatus for selecting a soil microbiome having increasing plant productivity may include operations including, using a generalized linear model, determining a cumulative growth effect size for each productivity response. In some embodiments, a generalized linear (GLM) model may be a generalized linear mixed model (GLMM). In some embodiments, a GLMM may include both fixed effects and random effects to account for hierarchical, grouped, or correlated data structures. It will be understood by one having ordinary skill in the relevant art that GLMMs extend the GLM framework by allowing for random variations across different levels of a dataset, such as plots within a field trial, trees within a forest stand, or microbial communities within distinct soil samples. Fixed effects in a GLMM may represent predictor variables with consistent effects across all observations, such as, e.g., soil nutrient composition, climate variables, or fungal diversity indices. Random effects may capture variation associated with repeated measures, spatial dependencies, or nested experimental designs, such as site-specific growth differences, individual plant responses to inoculation, or variability among geographically distinct plant communities. In some embodiments, a GLMM may be appliedAttorney Docket No.1723.2.WO2 PATENT using logistic, Poisson, negative binomial, gamma, or other link functions, depending on the distribution of the response variable.

[0107] In some embodiments, a GLM may be used to analyze measured plant traits, including, but not limited to, tree height, root collar diameter, change in height, cone volume, as response variables. Model selection criteria may be applied to optimize the top predictive response variables, ensuring the most significant growth indicators are retained. Cumulative growth effect sizes may be derived from repeated measures’ coefficients and tested for statistical significance to assess long-term inoculant impact. In some implementations, seedling survival may be estimated as the proportion of seedlings alive at the end of the study relative to the initial number of inoculated seedlings per source soil treatment. Uncertainty estimation may be performed using bootstrapping techniques, providing confidence intervals for model predictions. In some embodiments, a GLMM may be used to analyze measured plant traits in nursery inoculation experiments. For example, experimental data obtained from a nursery study can be used to evaluate the effects of multiple fungal inoculants on seedling growth by monitoring height and diameter changes over a six-month period. In some embodiments, a GLMM may be used to analyze measured plant traits in experimental field trials, where, e.g., a completely randomized block design is used. A GLMM may account for variability across different experimental blocks, ensuring accurate estimation of treatment effects. In some embodiments, spatially explicit models may be employed to account for georeferenced field data, e.g., incorporating kernel density estimation to model spatial dependencies in tree growth responses. For example, a field trial evaluating tree growth responses to soil inoculation can use a GLMM approach to control for differences in soil composition, climate, and geographic location. Incorporation of spatially explicit modeling may allow for a more refined analysis of localized environmental effects on plant productivity, aiding in the identification of optimal inoculation strategies for large-scale reforestation efforts.

[0108] According to some embodiments of the present invention, an apparatus for selecting a soil microbiome for increasing plant productivity may include operations including, using a distance-based multivariate model, determining differences between pairwise comparisons of fungal biodiversity data associated with each plant at each of the predetermined times. In some embodiments, fungal biodiversity data may be collected and analyzed at multiple predetermined time points to assess microbiome dynamics and their effects on plantAttorney Docket No.1723.2.WO2 PATENT growth. For example, in a reforestation trial, soil microbiomes from different donor forests may be used as inoculants for tree seedlings in a nursery or in field assay, with fungal community composition monitored over time, such as at predetermined times. Collected biodiversity data may be analyzed using permutational multivariate analysis of variance (PERMANOVA) to determine statistically significant differences in fungal community composition across time points and treatment groups. By comparing fungal diversity metrics at each stage, the influence of specific microbiome inoculants on plant productivity, nutrient cycling, and soil microbial interactions may be quantified, informing data-driven selection of optimal soil microbiomes for forestry and ecological restoration applications.

[0109] In some embodiments, operations may include combining an output from a machine learning model, a generalized linear model, and a distance-based multivariate model to execute a donor forest selection tool that is configured to select from the plurality of geographically distinct plant communities a soil microbiome having increasing plant productivity. In some embodiments, operations may include, using a weighted rank model, combining an output from a machine learning model, a generalized linear model, and a distance-based multivariate model to execute a donor forest selection tool that is configured to select from the plurality of geographically distinct plant communities a soil microbiome having increasing plant productivity. A weighted rank model may be configured to assign differential importance to predictive variables and model outputs based on their relative contributions to plant growth outcomes, ensuring that microbiome selection is optimized for productivity and ecological stability. A weighted rank model may combine outputs from three key computational models: (i) a machine learning model, which estimates a plant biomass prediction (ii) a generalized linear model (GLM) or generalized linear mixed model (GLMM), which estimates cumulative growth effect sizes, and (iii) a distance-based multivariate model, such as PERMANOVA, which quantifies pairwise differences in fungal biodiversity among soil microbiome samples and identifies clusters of microbiomes associated with higher plant productivity. A weighted rank model may apply scoring algorithms, weighted averaging, or multi-criteria decision analysis (MCDA) to rank soil microbiomes based on plant growth potential, microbiome stability, and biodiversity metrics. Weighting factors may be determined through adaptive learning processes, empirical field validation, or the like. Ranked outputs may be used to execute a donor forest selection tool, which may be configured to identify aAttorney Docket No.1723.2.WO2 PATENT soil microbiome from available geographically distinct plant communities that are predicted to maximize plant growth, resilience, and carbon sequestration potential.

[0110] In some embodiments, a donor forest selection tool may be used to integrate observational and experimental datasets to guide spatial biodiversity transfer for assisted reforestation. A donor forest selection tool may incorporate multiple data inputs, including, e.g., forest age, soil composition, environmental covariates, climate forecasts, and the like, along with results from nursery and field trial experiments and biodiversity metrics. By analyzing such variables, a donor forest selection tool may be configured to select donor soils for use in both controlled experimental trials and large-scale reforestation and restoration projects. For example, observational data on forest age and soil composition may be combined with predictive models trained on nursery and field trial data to identify donor forest sites that harbor microbial communities associated with enhanced plant growth and survival. A donor forest selection tool may use machine learning models, GLMs, GLMMs, and distance-based multivariate analyses to compare biodiversity patterns across geographically distinct donor forests, e.g., ensuring that soil microbiomes selected for transplantation are ecologically compatible with the target reforestation site. Unlike conventional site-specific agricultural input recommendations, this approach may be able to prioritize long-term ecological resilience by selecting donor microbiomes that support sustained plant productivity, soil health, and biodiversity recovery under future environmental conditions.

[0111] In some embodiments, observational data and experimental data may be collected from controlled experiments or from native plant communities (e.g., forests) to assess the effects of different soil microbiomes on plant productivity under standardized conditions. For example, plants can be inoculated with soil microbiomes sourced from geographically distinct donor forests, and growth parameters may be monitored over time. By way of further example, soil and root samples may be periodically collected for fungal biodiversity analysis, including DNA sequencing, metagenomic profiling, or quantitative PCR to determine the relative abundance of ectomycorrhizal fungal taxa. By way of further example, collected data may be fit into statistical and machine learning models to evaluate microbiome effects on plant growth.

[0112] In some embodiments, observational data may be collected from natural plant populations or native plant communities to identify microbial communities associated withAttorney Docket No.1723.2.WO2 PATENT high-productivity ecosystems. Data may be gathered from plant communities of varying ages, climates, and soil types to establish relationships between soil microbiome composition, tree growth metrics, and environmental covariates. In some embodiments, observational data may be used to train a supervised machine learning model, such as a boosted regression tree model, to predict plant biomass based on soil microbiome composition and environmental covariates. Additionally, spatially explicit models incorporating climate data, soil characteristics, and topography may be employed to refine predictions of plant productivity across different ecological conditions.

[0113] In some embodiments, the soil sample may comprise native soil harvested from the particular geographically distinct plant community. For example, native soil can include a volume of soil present in a native plant community that is unmodified in its composition post- harvest. In some embodiments, the soil sample may comprise a slurry comprising a volume of water mixed with soil harvested from the particular geographically distinct plant community. In some embodiments, a soil-to-water dilution ratio may be used to prepare a soil inoculation slurry for large-scale seedling inoculation. The soil inoculant may be diluted to create a slurry that ensures effective microbial delivery while facilitating ease of application. In some embodiments, a soil-to-water dilution ratio may be used to prepare a soil inoculation slurry for large-scale seedling inoculation. The dilution ratio may be 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, to 1:10 (soil to water by volume), wherein higher concentrations maintain greater microbial loads, while more diluted mixtures improve handling and uniform distribution. In some embodiments, the dilution ratio may range from 1:1 to 1:3, 1:2 to 1:5, 1:3 to 1:6, 1:4 to 1:7, 1:5 to 1:8, 1:6 to 1:9, and 1:7 to 1:10 (soil to water by volume). In some embodiments, the inoculation slurry may be applied at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 mL per seedling. In some embodiments, the inoculation slurry may be applied at 1 to 3 mL per seedling, 2 to 4 mL per seedling, 3 to 5 mL per seedling, 4 to 6 mL per seedling, 5 to 7 mL per seedling, 6 to 8 mL per seedling, 7 to 9 mL per seedling, and 8 to 10 mL per seedling.

[0114] In some embodiments, a method of the present invention may include growing plants ex situ relative to the particular geographically distinct plant community. For example, growing plants ex situ relative to the particular geographically distinct plant community can comprise growing plants in a greenhouse, nursery, non-natural plantation, or the like.Attorney Docket No.1723.2.WO2 PATENT

[0115] According to some embodiments of the present invention, a system for generating a fungal inoculant for increasing plant productivity may comprise a forest bioreactor comprising a feedstock, and an apparatus for selecting a soil microbiome having increasing plant productivity as disclosed herein. In some embodiments, a forest bioreactor may be designed to cultivate diverse soil microbial communities by providing a controlled substrate for fungal and bacterial colonization. Unlike traditional industrial bioreactors, which rely on closed-environment incubation, a forest bioreactor may involve placing organic materials within the forest floor, allowing native soil microbiota to colonize said organic materials over time. The bioreactor may be designed to optimize moisture retention, aeration, and nutrient availability, promoting natural proliferation of plant growth-promoting fungi and other microbes that may be used as inoculants for forestry and agricultural applications. In some embodiments, a feedstock for a forest bioreactor may include organic substrates capable of supporting microbial colonization and nutrient cycling. Feedstocks may comprise decomposable plant materials such as, e.g., leaf litter, wood chips, mulch, composted organic matter, nutrient-rich agricultural byproducts, and the like. The selection of feedstocks may be tailored to optimize microbial diversity, with different materials influencing the composition and functional traits of colonizing fungi and bacteria.

[0116] According to some embodiments of the present invention, a computer- implemented method for selecting a soil microbiome having increasing plant productivity may comprise: receiving, by one or more processors, observational data that is used to train a machine learning model, wherein the observational data comprise location-specific soil fungal community structure data, plant productivity data and environmental covariate data, wherein the observational data are collected from a plurality of geographically distinct plant communities; using the machine learning model, determining via the one or more processors, a plant biomass prediction comprising an estimate of plant height, plant diameter, and plant allometries at a geographically referenced site; receiving, by the one or more processors, experimental data comprising (i) productivity responses of plants grown ex situ relative to the particular geographically distinct plant community, wherein each plant is inoculated with an individual soil sample harvested from a particular geographically distinct plant community such that each plant is inoculated with a different soil sample, and (ii) fungal biodiversity data associated with each plant at predetermined times during plant growth; using a generalizedAttorney Docket No.1723.2.WO2 PATENT linear model, determining via the one or more processors, a cumulative growth effect size for each of the productivity responses; using a distance-based multivariate model, determining differences between pairwise comparisons of fungal biodiversity data associated with each plant at each of the predetermined times; and combining via the one or more processors, an output from the machine learning model, the generalized linear model, and the distance-based multivariate model to execute a donor forest selection tool that is configured to select from the plurality of geographically distinct plant communities a soil microbiome having increasing plant productivity.

In some embodiments, the predetermined times may include sampling from each week to each year.

[0118] In some embodiments, a rhizosphere fungal biodiversity may include a rhizosphere soil fungal biodiversity of a plant and a bulk soil fungal biodiversity of a plant. Rhizosphere soil fungal biodiversity may refer to the diversity of fungal species, strains, and the like, present in the soil region immediately surrounding and influenced by a plant’s roots. For example, the rhizosphere can be enriched by root exudates and can be inhabited by fungi that interact directly with a plant, e.g., including mutualists, pathogens, and other symbiotic species. Bulk soil fungal biodiversity may refer to a diversity of fungal species, strains, and the like, present in soil that may not be directly influenced by root activity but nevertheless in theAttorney Docket No.1723.2.WO2 PATENT vicinity of a plant rhizosphere. For example, the bulk soil fungal biodiversity can be representative of a background soil microbial community and can partially overlap with, or be entirely different from, a corresponding rhizosphere soil fungal biodiversity. In some embodiments, analysis of both rhizosphere and bulk soil fungal biodiversity may provide insights into plant-microbe interactions and the effects of fungal community composition on plant health and productivity.

In some embodiments, the method may further comprise adding a volume of water to the fungal inoculum to produce an inoculant slurry. In some embodiments, a forest bioreactor may be configured to enrich for fungal taxa that increase productivity of a plant relative to a control plant devoid of a fungal inoculum.

[0166] Figure 9 illustrates an example framework for selecting a soil microbiome having increased plant productivity. Observational data, including, e.g., location-specific plant productivity data 910, location-specific soil fungal community structure data 920, and location- specific environmental covariate data 930, can be received by a machine learning model 940 (e.g., a supervised machine learning model, such as, a boosted regression tree model) that can be configured to determine a plant biomass prediction, which can include, e.g., an estimate of plant height, plant diameter, and plant allometries at a geographically referenced site. The location-specific soil fungal community structure data 920 can include, e.g., after collecting soil microbiome biomass and sequencing nucleic acid content contained therein 921, applying a bioinformatics pipeline 922 to further process or interpret nucleic acid sequence information (e.g., removing primers or tags, enriching for specific gene regions or other markers, removing non-target sequences, etc.). The location-specific soil fungal community structure data 920, e.g., after applying a bioinformatics pipeline 922, can be further processed using a method of determining biodiversity, and optionally thereafter, dimensionally reduced 923. Next, the machine learning model 940 can be executed to generate a plant biomass prediction 950 (e.g., a tree biomass prediction). For example, the plant biomass prediction 950 can include plant height, plant diameter, and plant allometries at a geographically referenced site. The framework can also include receiving experimental data comprising productivity responses of plants grown ex situ relative to the particular geographically distinct plant community, wherein each plant is inoculated with an individual soil sample harvested from a particular geographically distinct plant community such that each plant is inoculated with a different soilAttorney Docket No.1723.2.WO2 PATENT sample, and fungal biodiversity data associated with each plant at predetermined times during plant growth.

The weighted rank model 980 can be used to determine a donor forest selection tool 990, which can be used as a decision-making tool to select an appropriate donor forest for use as a soil microbiome having increased plant productivity. EXAMPLES

[0167] The invention will now be described with reference to the following examples. It should be appreciated that these examples are not intended to limit the scope of the claims to the invention but are rather intended to be exemplary of certain embodiments. Any variations in the exemplified methods that occur to the skilled artisan are intended to fall within the scope of the invention. Example 1:

[0168] Patterns of Soil Biodiversity in Managed Timberlands: Native soil microbial communities associated with over 1,000 Loblolly Pine forests spanning from Texas to Virginia, along the Gulf and Atlantic Coast states, have been examined. To date, a total of 53,008 taxa have been identified within the soil fungal microbiome database, encompassingAttorney Docket No.1723.2.WO2 PATENT 18 phyla, 82 classes, 252 orders, 685 families, 1,737 genera, and 2,267 species. These data are summarized in Table 1.

[0169] Figure 10A-B illustrate sample locations and ectomycorrhizal fungal species diversity as a function of forest age are presented, respectively. As shown in Figure 10B, ectomycorrhizal species accumulation curves demonstrate that the number of species recovered increases as a function of sample number across a range of forests. Data show that ectomycorrhizal fungal diversity increases with forest age, as evidenced by a steeper accumulation curve.

[0170] Fungal Biodiversity Increases with Forest Age: The relationship between ectomycorrhizal fungal species richness and forest age is depicted in Figure 11, demonstrating that forest age significantly influences fungal community diversity with evidence suggesting a potential doubling of ectomycorrhizal species richness as forests mature. Figure 11 illustrates an estimated asymptotic species richness for ectomycorrhizal taxa across different forest age groups, derived from a nonlinear asymptote model fitted to mean species richness data across sites. The model was parameterized to estimate maximum species richness by randomly selecting 20 samples per group to represent mean average richness. The x-axis represents forest age groups, while the y-axis indicates estimated asymptotic species richness, with shapes distinguishing different age groups for visualization. Sampling depth refers to the number of individual observations, measurements, or data points collected from a given sample or study area, representing the thoroughness or resolution of the sampling effort. These findings underscore the importance of long-term forest management strategies in promoting biodiversity recovery and the conservation of mycorrhizal fungi in managed ecosystems.

[0171] Inoculation with donor soil significantly accelerates the rate at which fungal biodiversity can recover within managed forest systems: Figure 12 demonstrates how species richness across control plant seedlings (seedlings devoid of a donor soil inoculum), donor soil inoculated plant seedlings, and reference forest soils (positive control soils as found in nature, or “wild / native soils”). Results indicate that donor soil inoculated plant seedlings host nearly as many fungal species as reference forest soils, demonstrating that inoculating plant seedlings with a growth promoting fungal consortium identified using a donor soil inoculant facilitates soil biodiversity and accelerates plant productivity.Attorney Docket No.1723.2.WO2 PATENT Example 2

[0172] Identifying a “healthy forest microbiome”: To assess fungal biodiversity and its role in tree growth, data were collected from hundreds of forests to document tree growth rates and identify fungal species present using DNA sequencing. For each stand, additional environmental variables, including climate, stand management, and soil characteristics, were incorporated. Machine learning models were applied to integrate these data, controlling for stand factors, soils, and climate, to determine which fungal species are associated with growth promotion.

[0173] The fungal biodiversity data are highly complex, with thousands of species observed across all sampled forests. The health of the forest microbiome was assessed by calculating alpha and beta diversity metrics derived from normalized species relative abundance data obtained through eDNA surveys. These metrics provided insights into both within-sample diversity (alpha diversity) and between-sample diversity (beta diversity). To simplify and interpret this multidimensional dataset, dimensionality reduction techniques were applied (e.g., PCA, PCoA, NMDS, etc.), distilling the information into a single comprehensive metric representing overall microbiome diversity and health.

[0174] Relationship Between Fungal Biodiversity and Forest Productivity: The variation in forest productivity as a function of a key fungal biodiversity indicators, indicates that the fungal microbiome accounts for a substantial proportion of the observed variation in tree growth. Forests with higher values of the fungal biodiversity indicator exhibit increased growth rates, indicating a strong association between fungal diversity and forest productivity. Example 3

[0175] To produce a fungal inoculant containing a consortium of growth promoting fungi, a bioreactor system was designed to facilitate the cultivation and expansion of fungal microbial communities under controlled conditions. To develop a sustainable method for generating wild microbial inoculants from forest environments, an approach utilizing “in-forest bioreactors” was implemented. These bioreactors are established by burying multiple organic substrates at a depth of 10–15 cm beneath the soil surface, allowing microbial colonization over time. Organic substrates serve as feedstock for mycorrhizal fungi and included pine straw, pine mulch, peat moss, and compost.Attorney Docket No.1723.2.WO2 PATENT

[0176] This process allowed natural microbial colonization with minimal environmental disturbance. Shallow areas were excavated and then filling with organic material that included the feedstock, and subsequent left to rest to allow for colonization by local forest microbiota. After colonization, the colonized organic material was harvested as an alternative to directly extracting soil. To ensure sustainability, each batch of removed material is replaced with fresh substrate, thereby maintaining mass balance within the site.

[0177] The concept parallels industrial bioreactors, which are engineered to optimize microbial growth by controlling parameters such as temperature, pH, oxygen levels, and nutrient availability. While industrial bioreactors are effective for cultivating specific microbial strains, they have demonstrated limitations in supporting the growth of diverse, ecologically relevant microbial communities. Research has shown that donor forests naturally support and replicate biodiverse microbial communities, making them suitable environments for in situ microbial propagation.

[0178] Rather than supplying a bioreactor with an external feedstock, organic substrates are introduced into the forest floor, where they are colonized over time by soil microbial communities. Our data indicate that tree roots and native soil fungi will colonize these materials over a period of months, producing an enriched inoculant that can be harvested for application in reforestation efforts.

[0179] Pilot studies have identified multiple organic substrates capable of capturing soil microorganisms and enhancing seedling growth when applied as inoculants. Among the tested materials, longleaf pine straw, a compost-manure mixture, and brown wood mulch were shown to be the most effective as feedstocks. Fungal composition analyses revealed differences in both the structure and function of microbial communities colonizing each substrate. This variation is analogous to how industrial bioreactors selectively cultivate different microbial strains by modifying nutrient and environmental conditions.

[0180] By establishing large-scale forest bioreactors, reliance on soil extraction is minimized, allowing for the collection of forest-derived microbial feedstocks instead. The harvested material is continuously replenished with fresh organic substrate, ensuring the sustainability of inoculant production and maintaining ecological balance at the site. Example 4Attorney Docket No.1723.2.WO2 PATENT

[0181] The example framework for selecting a soil microbiome having increased plant productivity as shown in Figure 9 was used to identify and select candidate donor forests harboring wild, growth-promoting fungi. The efficacy of microbial communities from these donor forests as inoculants was demonstrated through rigorous field trials conducted under real forestry conditions. Each trial was set up as a block-randomized controlled trial, analogous to randomized controlled trials (RCTs) as shown in Figure 13E.

[0182] Field trials consisted of four treatments: three microbial community inoculants selected by the example framework shown in Figure 9, and one control. Each trial encompassed approximately two acres, containing about 1,000-1,200 commercially sourced seedlings. The trial designs were validated through statistical power analyses and approved by the NC State Forest Productivity Cooperative.

[0183] Fifteen field trials have been established across the southern US loblolly pine region as shown in Figure 13D. Data from three, one-year-old field trials are presented below, highlighting only the best-performing fungal community treatments.

[0184] Field Trial 1 (Northern Georgia Piedmont): Tree survival exceeded 90% across all treatments, showing no significant differences. However, the top-performing fungal inoculant produced approximately 60% greater tree volume than controls. Projected gains at the end of a rotation are approximately 3,249 cubic feet of additional wood per acre and 81 additional tons of Carbon Dioxide Equivalent (CO2e) per acre. Results are illustrated as shown in Figure 13A.

[0185] Field Trial 2 (Southern Georgia Coastal Plain): Survival rates also exceeded 90% without detectable differences among treatments. The best fungal inoculant yielded approximately 30% greater tree volume than controls. This translates to approximately 2,881 additional cubic feet of wood per acre and 72 additional tons of CO2e per acre by rotation end. Results are illustrated as shown in Figure 13B.

[0186] Field Trial 3 (Southern North Carolina Coastal Plain): This trial, independently measured by the NC State Forest Productivity Cooperative, experienced substantial flooding, causing an overall survival rate of 67%. The highest-performing fungal inoculant achieved an 80% survival rate compared to a 60% survival rate for controls. Although aboveground volume differences were not observed in the first year, increased survival rates imply significant long-Attorney Docket No.1723.2.WO2 PATENT term benefits, potentially determining the viability of a planting. Results are illustrated as shown in Figure 13C.

[0187] Conclusion: Across all trials, Funga’s microbiome restoration approach substantially increased tree growth or survival rates, comparable to genetic improvement or forest fertilization methods known in the art. These findings align with global studies documented in scientific literature, validating the efficacy of microbial inoculants for enhanced forestry performance.
