Solution Overview
Problem
Conventional agriculture relies heavily on chemical fertilizers, leading to soil and water pollution and greenhouse gas emissions, as well as high-temperature disorders and disease outbreaks in crops, necessitating an environmentally friendly and multifunctional solution.
Innovation Solution
A microbial material produced through fermentation using a mixture of thermophilic microorganisms, including Bacillus brevis and Bacillus stearothermophilus, which reduces nitrate ions in soil, promotes denitrification, and enhances plant functionality by activating nitrate transporters, increasing antioxidant production, and providing heat resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If chemical fertilizers are used to improve crop production, then productivity increases, but soil and water pollution occurs and greenhouse gas emissions increase
Solution Approach 1:
The patent converts harmful nitrate ions in soil into beneficial nitrogen gas through denitrification. Thermophilic microorganisms are introduced to transform excess nitrate (a pollutant) into nitrogen gas (a harmless substance), thereby eliminating pollution while maintaining soil fertility for crop production.
Solution Approach 2:
Thermophilic microorganisms serve as intermediaries between chemical fertilizers and crops. Instead of directly applying chemical fertilizers that cause pollution, the microorganisms process the nutrients and deliver them to plants in a controlled manner, reducing harmful emissions while maintaining productivity.
2Productivity
If conventional agricultural methods are used to maintain crop health, then productivity is maintained, but high-temperature disorders and disease outbreaks occur
Solution Approach 1:
The patent enhances plants' self-protection capabilities by introducing thermophilic microorganisms that stimulate the plants' own defense mechanisms. The microorganisms trigger heat shock protein production and antioxidant synthesis within the plants, enabling them to self-protect against high-temperature stress and diseases without external intervention.
Solution Approach 2:
The thermophilic microorganisms are applied in advance to prepare plants for environmental stresses. By pre-stimulating heat shock protein expression and antioxidant systems before actual stress occurs, the plants are primed to resist high-temperature disorders and disease outbreaks, maintaining productivity under adverse conditions.
3Object-generated harmful factors
If thermophilic microorganisms are used for denitrification and plant enhancement, then environmental sustainability improves, but manufacturing complexity increases
Solution Approach 1:
The patent combines multiple functions into a single microbial preparation: denitrification, plant growth promotion, stress resistance enhancement, and pathogen suppression are all achieved through one fermented microbial product. This consolidation simplifies application compared to using multiple separate treatments.
Solution Approach 2:
The fermentation process parameters (temperature, time, microbial strains) are optimized to produce a stable, standardized product. By controlling these parameters, the complex biological process yields a consistent preparation that is easy to store and apply, reducing manufacturing complexity despite the sophisticated biochemistry involved.
