Microbial Bio-stimulant Reduces Nitrogen Fertilizer Dependency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The excessive use of nitrogen fertilizers in agriculture leads to environmental issues such as nitrate leaching, greenhouse gas emissions, and inefficient nitrogen utilization, with existing nitrification and urease inhibitors providing variable results and a need for alternative methods to enhance plant growth while reducing nitrogen input.
Innovation Solution
A microbial bio-stimulant composition, produced through fermentation of microorganisms like Lactobacillus and Saccharomyces, is applied alone or combined with urea and other agricultural compounds to stimulate nitrogen uptake and amino acid synthesis, reducing the need for nitrogen fertilizers and improving plant growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If nitrogen fertiliser is applied to increase pasture production, then plant growth is improved, but environmental pollution increases due to nitrate leaching and greenhouse gas emissions
Solution Approach 1:
The patent introduces nitrification inhibitors as intermediary substances that mediate between nitrogen fertiliser application and environmental protection. These inhibitors act as a buffer to control the conversion of ammonium to nitrate, thereby reducing nitrate leaching and associated greenhouse gas emissions while maintaining pasture production benefits
Solution Approach 2:
The patent modifies the chemical and biological parameters of the soil nitrogen cycle by introducing nitrification inhibitors. This changes the rate and pathway of nitrogen transformation, converting a potentially harmful rapid nitrification process into a controlled process that reduces environmental impact while preserving agricultural productivity
2Object-generated harmful factors
If nitrification inhibitors are used to reduce nitrate leaching, then environmental impact is reduced, but plant growth response becomes variable depending on application timing and soil conditions
Solution Approach 1:
The patent employs dynamic application strategies for nitrification inhibitors, adjusting timing, dosage, and method based on real-time soil conditions, weather forecasts, and crop needs. This dynamic approach ensures consistent plant growth responses by adapting to varying environmental conditions rather than using fixed application protocols
3Productivity
If high amounts of nitrogen fertiliser are applied to address seasonal deficits, then pasture production increases, but energy consumption and resource depletion increase
Solution Approach 1:
The patent implements preliminary action by applying nitrification inhibitors before nitrogen fertiliser to pre-condition the soil environment. This preliminary step ensures that subsequent nitrogen applications are more efficient and better utilized by plants, reducing the total amount of nitrogen fertiliser needed and thereby decreasing the energy and resources required for its production
