TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The soil conditioning agent is prepared by roasting potassium feldspar at 600-700 degrees C for 4-5 hours, cooling, grinding into 40-50 meshes powder, dissolving the rest of raw materials in water, mixing with potassium feldspar powder, stirring, granulating, and drying. The nutrient soil is prepared by adding water to food residue, fallen leaves, bagasse, shredded coconut, dairy manure, soybean meal, and wintergreen oil, stirring, covering with plastic film, and composting for 15-20 days to obtain rotten organic fertilizer; dissolving EDTA ferric sodium salt, ferrous sulfate, copper sulfate, boric acid, sodium selenite, magnesium sulfate, and sodium molybdate, adding organic fertilizer and the rest of raw material, fully mixing, granulating, and drying.
