Solid/Semi-Solid Fertilisers TRIZ Cases
- Spherical Urea-Aldehyde Granules With Higher Crush Strength
Spheronized and extruded urea-aldehyde granules use binders to resist powdering, improve blending, and extend nutrient release.
- tBHQ Urease Inhibitor Composition for Reducing Urea Volatilization
Using tBHQ in urease inhibitor compositions helps retain nitrogen from urea by limiting ammonia volatilization while improving stability and shelf life.
- Biodegradable Fertilizer Coating Resin for Controlled Nutrient Release
A biodegradable polyester coating balances nutrient release control, coating uniformity, and lower microplastic pollution in slow-release fertilizers.
- Multilayer Polyurethane-Wax Coatings for Controlled Fertilizer Release
Multilayer polyurethane and polyolefin wax layers help prevent premature coating failure while extending controlled fertilizer release.
- Biodegradable Polymer Coatings for Controlled-Release Fertilizer Granules
Non-biodegradable fertilizer coatings create environmental concerns; PBSA-based blends enable controlled nutrient release and soil degradation within two years.
