Fertilizer Mixture with Pyrazole Inhibitor and Monoamine Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nitrogen-containing fertilizers face issues such as caking during storage, volatility of nitrification inhibitors, and significant nitrogen loss through leaching and denitrification, leading to reduced fertilization efficacy and environmental pollution.
Innovation Solution
A mixture comprising a nitrogen-containing fertilizer, a nitrification inhibitor selected from specific pyrazole compounds, and a composition of primary and/or secondary alkyl and/or alkylene monoamines, along with aluminium stearate and fatty alcohol, which treats the fertilizer mixture to prevent caking, enhance stability, and reduce nitrogen emissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pyrazole compounds are used as nitrification inhibitors, then fertilization efficacy is improved and nitrogen loss is reduced, but volatility increases causing losses during storage
Solution Approach 1:
The patent combines pyrazole nitrification inhibitor with polyethylene glycol to form a composite material. The polyethylene glycol acts as a carrier that reduces the volatility of the pyrazole compound while maintaining its nitrification inhibition function. This composite approach allows the inhibitor to remain effective during storage and application.
2Productivity
If nitrogen-containing fertilizers are used to support plant growth, then plant productivity is improved, but caking occurs during storage
Solution Approach 1:
The patent uses polyethylene glycol as an intermediary substance that coats the fertilizer granules. This coating layer acts as a barrier that prevents direct contact between fertilizer particles, thereby preventing caking during storage while allowing the fertilizer to maintain its nutritional value and effectiveness.
3Object-generated harmful factors
If nitrification inhibitors are applied to reduce nitrogen emissions, then environmental pollution is reduced, but handling and application becomes more complex
Solution Approach 1:
The patent combines the nitrification inhibitor with the fertilizer in a single formulation using polyethylene glycol as a common carrier. This merging of the inhibitor and fertilizer into one product simplifies handling and application, as farmers only need to apply one substance instead of separately managing fertilizer and inhibitor.
