DETAILED DESCRIPTION - Bioorganic fertilizer comprises 90-100 pts. wt. rice hull, 87-93 pts. wt. rice chaff, 68-74 pts. wt wheat bran, 64-70 pts. wt. corncob, 50-55 pts. wt. medicinal residue, 1-2 pts. wt. ammonium molybdate, 2-4 pts. wt. ferrous sulfate, 4-6 pts. wt. zinc dialkyldithiophosphate, 5-7 pts. wt. effective microorganisms, 16-21 pts. wt. potassium hydroxide, 3-4 pts. wt. magnesium hydroxide, 1-2 pts. wt. zinc sulfate, 7-9 pts. wt. polyvinyl alcohol, 8-10 pts. wt. soil conditioning agent, and water (suitable amount). The soil conditioning agent comprises 10-20 pts. wt. bamboo charcoal, 1-2 pts. wt. nano carbon powder, 4-5 pts. wt. sodium metasilicate, 17-19 pts. wt. methyl methacrylate, 3-4 pts. wt. selenium yeast, 2-3 pts. wt. copper sulfate, 2-3 pts. wt. zinc gluconate, 1-2 pts. wt. magnesium chloride, 2-3 pts. wt. ammonium molybdate, 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, 2-3 pts. wt. citric acid, 1-2 pts. wt. titanium dioxide, 2-3 pts. wt. ammonium persulfate, and 1-2 pts. wt. methyltriethoxysilane. The soil conditioning agent is prepared by mixing the above-mentioned methyl methacrylate, dipentaerythritol hexaacrylate, bamboo charcoal, nano carbon powder, Eucalyptus oil, titanium dioxide, ammonium persulfate and methyl triethoxysilane, mixing the remaining raw materials with the obtained mixture, adding vinegar to the mixture, and mixing the obtained product in high-speed disperser. An INDEPENDENT CLAIM is included for method for preparing the above-mentioned bioorganic fertilizer, which involves (a) mixing the above-mentioned ammonium molybdate, ferrous sulfate, potassium hydroxide, magnesium sulfate and zinc sulfate, mixing the obtained mixture with water and soil conditioning agent, concentrating the mixture, drying the concentrate, and granulating the dried product, (b) mixing the above-mentioned zinc dialkyldithiophosphate, polyvinyl alcohol and the remaining raw materials, maintaining moisture content of the mixture to 40-45%, stirring the mixture, anaerobically fermenting the mixture at room temperature for 20-30 days, turning the fermented product once for every 3-4 days, drying the fermented product, and grinding the dried product, and (c) mixing the products obtained in steps (a) and (b), cooling the mixture, dissolving polyvinyl alcohol in water at room temperature, and spraying the obtained product on the cooled product.
