Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional organic fertilizers face issues with microorganism inclusion, reduced fermentation speed, and storage difficulties, leading to decreased soil reforming effects and crop productivity.
Innovation Solution
A microbial coated organic fertilizer is developed by coating the surface of organic fertilizers with a microbial culture medium, using components like castor meal, rice bran, and microbial culture media, enhancing mechanical properties and fermentation rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If microorganisms are introduced to carriers such as rice straw, crushed wood, or natural minerals, then organic fertilizer can be manufactured with microorganism inclusion, but fermentation speed is reduced and complete fermentation becomes difficult
Solution Approach 1:
The invention segments the microorganism inclusion approach into two distinct components: (1) carriers containing microorganisms (rice straw, crushed wood, natural minerals) and (2) microbial culture medium sprayed as coating. This segmentation allows the carriers to provide structural support and initial microorganism introduction, while the sprayed coating delivers concentrated, viable microorganisms directly to the organic fertilizer surface, enabling complete fermentation without sacrificing fermentation speed
Solution Approach 2:
The microbial culture medium acts as an intermediary substance that bridges the gap between carriers and organic fertilizer. Instead of relying solely on carriers to deliver microorganisms (which results in slow fermentation), the culture medium serves as a concentrated intermediary delivery system that coats the organic fertilizer particles, ensuring adequate microorganism population and distribution for complete and rapid fermentation
2Ease of manufacture
If organic fertilizers are used in the form of solidified organic fertilizers, then storage and use difficulties are resolved, but microorganism inclusion and fermentation effectiveness are reduced
Solution Approach 1:
The invention applies preliminary action by coating the solidified organic fertilizer particles with microbial culture medium before use. This pre-coating ensures that viable microorganisms are present on the particle surface, ready to initiate fermentation immediately upon application to soil, thereby maintaining both storage stability of the solidified form and fermentation effectiveness
Solution Approach 2:
The invention applies local quality by concentrating microorganisms specifically on the surface of organic fertilizer particles through spraying. The interior of the solidified particles maintains its stable, stored state, while the surface layer is enriched with microbial culture medium, creating a localized zone of high microbial activity that initiates rapid fermentation when contact with soil moisture occurs
3Ease of manufacture
If microorganisms are included in the form of a carrier, then organic fertilizer can be manufactured, but the effect of soil reforming and crop growth promotion deteriorates
Solution Approach 1:
The invention changes the parameter of microorganism delivery from carrier-bound (low viability, slow release) to sprayed coating (high concentration, immediate availability). By altering how microorganisms are introduced and distributed, the fertilizer maintains ease of manufacture through standard coating equipment while dramatically improving the biological activity and crop growth promotion effects through enhanced microbial effectiveness
