Calcareous Fertilisers TRIZ Cases
- Wet-Chemical Ash Treatment for Chloride-Free Phosphorus Recovery
Multi-stage acid digestion separates phosphorus, calcium, and aluminum from incineration ash while avoiding chloride contamination and recycling acids.
- Calcium Sulfate Urea Adduct Fertilizer for Stable Nitrogen Blends
A calcium sulfate urea adduct stabilizes nitrogen fertilizer blends, reducing moisture, clumping, and nitrogen loss in soil.
- High-Concentration Sulphate Salt Suspension Without Sedimentation
Suspending agents and dispersants keep high-load sulphate salt suspensions stable for at least a month by preventing precipitation and sedimentation.
- Ammonium Nitrate Fertilizer Composition for Low Dusting and Caking
Biotite with calcium compounds and magnesium nitrate improves ammonium nitrate fertilizer strength, lowers dusting and caking, and reduces explosive risk.
- Phosphogypsum Leaching and Ion Exchange for 226Ra Recovery
Single-stage leaching and ion exchange recover 226Ra from phosphogypsum while purifying gypsum for construction use.
- Oolitic Aragonite Turf Infill for Cooling and Ammonia Neutralization
Microporous oolitic aragonite infill improves turf drainage and cooling while neutralizing ammonia and resisting compaction.
- Silica Mineral Suspension Fertilizer for Faster Silicon Delivery
Aqueous silica mineral suspensions replace dusty granules to improve silicon dissolution, safer handling, and fertilizer application efficiency.
- Agglomerated Multi-Ingredient Fertilizer for Soil Acidity and Sulphur Balance
Combining carbonate-clay powder, organic additives, and sulphate sulphur helps neutralize acidic soil while improving nutrient balance and application uniformity.
- UCS Fertilizer Granules With Staged Moisture-Controlled Granulation
A staged UCS adduct and granulation process controls slurry moisture to preserve pumpability while producing stable, high-nitrogen fertilizer granules.
- Hydroponic Wrapper Nutrient Composition for Yield and Leaf Strength
Stage-specific calcium, magnesium, iron, boron, and manganese dosing in hydroponic wrapper cultivation improves yield and leaf tensile force.
- Geological carbon sequestration and hydrogen production structure and method based on the spontaneous reaction of water-CO<sub>2</sub>-active minerals
Active mineral layers mineralize injected CO2 while reacting with water to generate hydrogen, cutting sequestration cost and avoiding separate H2 production.
- In-Home Hydroponic Unit Using Cyanobacteria Biofertilizer
Anabaena PCC 7120 in modified BG-11 N0 media enables compact indoor hydroponics with nitrogen fixation, tap water use, and less chemical fertilizer.
