Solution Overview

Problem

Current methods for improving biomass production from cereal crops, such as using microbial inocula and fertilizers, often prioritize microbial activity over plant nutrition, and the use of yeasts as agricultural fertilizers is uncommon, limiting their effectiveness in enhancing crop yields.

Innovation Solution

Applying inactivated yeasts or yeast derivatives, specifically from the Saccharomyces genus, as seed coatings at low doses around cereal seeds to enhance microbial activity and plant nutrition, thereby improving biomass production without additional active ingredients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If active yeasts or yeast derivatives are applied to soil as fertilizers, then plant nutrition is improved, but the effectiveness is limited due to uncommon usage and high application quantities required

Engineering Contradiction:
Improvebiomass productionVSAvoidyeast application quantity
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The yeast coating is applied to seeds before sowing, allowing the nutritional effect to be delivered at the critical early growth stage when the plant most needs it. This preliminary action concentrates the effect where and when it is most needed, eliminating the need for large quantities applied later to the soil.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The yeast coating is applied locally to the seed surface rather than being distributed broadly in the soil. This localized application ensures that the nutritional benefits are concentrated at the root zone where the plant can access them most efficiently, maximizing the effect per unit of yeast applied.

Inventive Principle:
Principle #3Local quality

2Productivity

If high doses of yeast are applied to soil, then some nutritional effect is achieved, but the cost-effectiveness deteriorates due to high application rates

Engineering Contradiction:
Improvecrop yieldVSAvoidfertilizer dose
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

Applying the yeast coating to seeds before sowing ensures that the nutritional effect is delivered at the most critical growth stage, maximizing the biological efficiency of the applied material and achieving better results at lower doses compared to soil application.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The seed coating method concentrates the yeast material precisely where it is needed - at the seed-root interface - ensuring optimal utilization by the emerging plant. This localized delivery system eliminates waste and achieves maximum effect per unit of material applied.

Inventive Principle:
Principle #3Local quality

3Productivity

If microbial inocula are used to promote soil microbial activity, then biological activity in soil is enhanced, but plant nutrition is not optimized as the primary focus remains on microbial populations rather than direct plant benefit

Engineering Contradiction:
Improvebiomass productionVSAvoidapplication method flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The yeast coating serves multiple functions simultaneously: it provides direct nutrition to the plant, protects the seed, and introduces beneficial microorganisms. This multi-functionality makes the solution versatile and adaptable to different cropping systems without requiring separate interventions for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)
