DETAILED DESCRIPTION - Bio-organic fertilizer comprises 85-100 pts. wt. dairy manure, 79-90 pts. wt. rabbit manure, 15-23 pts. wt. lees, 12-17 pts. wt. cassava residue, 1-2 pts. wt. zinc sulfate, 1-2 pts. wt. EDTA chelated manganese, 1-1.5 pts. wt. borax, 1-2 pts. wt. ammonium citrate, 2-3 pts. wt. zinc dihydrogen phosphate, 1-2 pts. wt. zinc borate, 30-35 pts. wt. carbamide, 25-30 pts. wt. ammonium sulfate, 16-22 pts. wt. potassium chloride, 1-2 pts. wt. manganese dioxide, 4-6 pts. wt. essential microorganism, 8-10 pts. wt. soil modifying agent, and water (remainder). The soil modifying agent comprises 10-20 pts. wt. sepiolite, 1-2 pts. wt. nanocarbon powder, 4-5 pts. wt. sodium metasilicate, 17-19 pts. wt. methyl methacrylate, 3-4 pts. wt. selenium yeast, 2-3 pts. wt. copper, 2-3 pts. wt. zinc, 1-2 pts. wt. magnesium chloride, 2-3 pts. wt. ammonium sulfate, 1-2 pts. wt. boric acid, 4-6 pts. wt. dipentaerythritol hexaacrylate, 30-40 pts. wt. vinegar, 2-3 pts. wt. chitosan, 1-2 pts. wt. Eucalyptus oil, and 0.5-1 pts. wt. sodium nitrophenolate compound. The soil modifying agent is prepared by mixing methyl methacrylate, dipentaerythritol hexaacrylate, sepiolite, and nanocarbon powder, uniformly adding the Eucalyptus oil to the mixture, adding remaining ingredients excluding vinegar solution to the mixture, completely stirring the mixture, adding vinegar solution, and subjecting the mixture to high speed dispersion. An INDEPENDENT CLAIM is included for method for manufacturing the above-mentioned bio-organic fertilizer, which involves (a) mixing zinc sulfate, EDTA chelated manganese, borax, ammonium citrate, zinc dihydrogen phosphate, zinc borate, carbamide, ammonium sulfate, potassium chloride and manganese dioxide, adding water (suitable quantity), uniformly adding soil modifying agent to the mixture, continuously and uniformly stirring the mixture, and concentrating and drying the stirred mixture to prepare granules, (b) mixing the remaining components excluding urea, maintaining moisture content of the mixture to 40-45%, stirring and sealing the mixture, performing anaerobic fermentation at room temperature for 20-30 days, turning the mixture for every 3-4 days, drying the fermented material and grinding and granulating the dried materials, and (c) mixing the products obtained in step (a) and step (b), cooling the mixture, and drying and sieving the cooled mixture.
