Solution Overview

Problem

Current methods for biofertilization of arable soils face challenges in ensuring the endogeneity and effective reintroduction of azotobacterial biomasses, as the non-contiguous distribution of bacteriological soils and lack of a consensus on strain proportions in consortia hinder the formation of specific agro-micro-pedoclimatic consortia, making it difficult to target and adapt bacterial inocula effectively.

Innovation Solution

The proposal involves assigning an agro/micro-pedoclimate (AMPC) value to soil samples based on clay and organic carbon content and pH, allowing for the formation of endogenous azotobacterial consortia adapted to specific AMPCs, using simple soil analysis to classify soil samples into clayey classes and determining minimax thresholds for segmentation, thereby ensuring the endogeneity of reintroduced bacterial populations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If exhaustive soil characterization is performed to ensure endogeneity of bacterial biomasses, then the reliability of biofertilization is improved, but the device complexity and cost increase significantly

Engineering Contradiction:
Improveendogeneity of bacterial biomassVSAvoidsoil characterization complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the essential characteristics needed to define endogeneity (clay content, organic carbon, pH) from the complete soil characterization process. By isolating these key parameters that determine AMPC classification, the method eliminates the need for exhaustive analysis while maintaining reliability in identifying suitable bacterial biomasses for reintroduction.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies local quality by creating specific AMPC classifications tailored to local soil conditions. Instead of requiring complete characterization of all soil properties, the method focuses on locally relevant parameters (clay, organic carbon, pH) that specifically determine the agro-micro-pedoclimatic conditions, allowing targeted identification of endogenous bacterial strains without comprehensive analysis.

Inventive Principle:
Principle #3Local quality

2Measurement precision

If the number of cartographic units is increased to improve precision of soil classification, then the measurement precision is improved, but the loss of time and complexity increase

Engineering Contradiction:
Improvesoil classification precisionVSAvoidclassification time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent changes the parameters used for classification by focusing on three key soil properties (clay content, organic carbon, pH) rather than using numerous cartographic units. This parameter transformation allows precise AMPC classification while avoiding the time loss associated with evaluating multiple cartographic units, as the classification is directly derived from measured soil parameters.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If consensus on strain proportions in consortia is established to improve manufacturing precision, then the ease of manufacture is improved, but the adaptability to different AMPCs decreases

Engineering Contradiction:
Improveconsortia composition consistencyVSAvoidadaptability to different AMPCs
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making consortium composition adaptable to different AMPC conditions. Instead of fixed strain proportions, the method allows the relative proportions of bacterial strains in consortia to be adjusted according to the specific AMPC classification of the target soil, thereby maintaining manufacturing precision through systematic adjustment while preserving adaptability to various agro-micro-pedoclimatic conditions.

Inventive Principle:
Principle #15Dynamics

AI summary

The method involves segmenting classes into sub-groups, and designating agro/micro-pedoclimate (AMPC). The AMPC is attributed to a set of samples of agricultural plot and small island. The plot and small island are sampled to determine values of variables (VAR) of clay and organic carbon contents and pH value of water or potassium chloride. Homogeneous classes or groups are initially formed at initial state of primary main components from pedagogical observation data and segmented at secondary main components into numbers that are equivalent to number of AMPCs due to potential soil samples.
