USE - Organic fertilizer.    ADVANTAGE - The organic fertilizer has wide raw material sources, does not produce waste, has reduced production cost, has extended release time, improves water and nutrients retention property of soil, and increases absorbing performance, buffering performance and resistance performance of soil.    DETAILED DESCRIPTION - Organic fertilizer comprises 20-30 pts. wt. sorghum straw charcoal, 6-8 pts. wt. river silt, 2-3 pts. wt. potassium ore, 1-2 pts. wt. dicalcium phosphate, 4-5 pts. wt. EDTA chelated zinc, 4-6 pts. wt. dried sweet potatoes, 5-6 pts. wt. fulvic acid, 4-5 pts. wt. durian shell, 3-4 pts. wt. sunflower seed oil residue, 4-5 pts. wt. potassium sulfate, 6-8 pts. wt. ammonium nitrate, 35-45 pts. wt. rapeseed straw, 6-8 pts. wt. asparagus, 8-10 pts. wt. safflower seed oil residue, 20-30 pts. wt. soil conditioner, and water. The soil conditioner comprises 8-12 pts. wt. Agaricus blazei mushroom residue, 40-60 pts. wt. beer sludge, 10-15 pts. wt. urea, 20-30 pts. wt. sawdust, 5-6 pts. wt. ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid) (EDDHA) chelated iron, 5-6 pts. wt. amino acid chelated copper, 5-6 pts. wt. amino acid chelated magnesium, 5-6 pts. wt. amino acid chelated calcium, 5-6 pts. wt. amino acid chelated boron, 5-6 pts. wt. amino acid chelated manganese, 5-6 pts. wt. amino acid chelated zinc, 2-3 pts. wt. polyacrylamide, 1-2 pts. wt. feldspar powder, and 4-5 pts. wt. effective microorganisms (EM) microbial inoculum. It is prepared by mixing EDDHA chelated iron, amino acid chelated copper, amino acid chelated magnesium, amino acid chelated calcium, amino acid chelated boron, amino acid chelated manganese, and amino acid chelated zinc; grinding mixture into fine powder mixture; mixing beer sludge and sawdust; adding EM microbial inoculum and Agaricus blazei mushroom residue; adjusting maximum water holding capacity of compost at 60-70%; piling up for thermophilic composting for 6-8 days; turning for 4-5 times while maintaining temperature at 50-60 degrees C; continuously fermenting for 25-35 days; drying and crushing beer sludge compost; uniformly mixing beer sludge compost and fine powder mixture; adding urea; spray granulating to obtain spherical particles that are partially dry and little sticky; spray mixing polyacrylamide and potassium feldspar powder on outer surface to obtain coated particles; cooling coated particles; and drying to obtain soil conditioner. An INDEPENDENT CLAIM is included for preparation of organic fertilizer by mixing dried sweet potatoes, river silt, durian shell, sunflower seed oil residue, sorghum straw charcoal, rape straw, asparagus, and safflower seed oil residue; adding mixture into fermentation tank; fermenting for 25-35 days at 45-65 degrees C while turning over every 5-8 days for oxygen passage; finishing fermentation to obtain fermented material; mixing and grinding EDTA chelated zinc, potassium sulfate, fulvic acid, and ammonium nitrate; stirring; adding fermented material; uniformly mixing; granulating to obtain granulated particles; mixing potassium ore, dicalcium phosphate with water; stirring to obtain slurry; uniformly spraying slurry into outer surface of granulated particles; drying; uniformly mixing remaining materials; and packaging into bags to obtain product.
