DETAILED DESCRIPTION - Selenium-enriched bioorganic fertilizer comprises 56-59 pts. wt. soy sauce residues, 45-49 pts. wt. soybean residues, 46-51 pts. wt. bean curd residues, 90-100 pts. wt. rotten chicken manure, 34-39 pts. wt. rice bran, 1-2 pts. wt. ammonium citrate, 4-6 pts. wt. calcium lignosulfonate, 3-5 pts. wt. calcium chloride, 12-14 pts. wt. charcoal powder, 7-9 pts. wt. plant fiber, 1-2 pts. wt. sodium selenate, 26-29 pts. wt. urea, 8-10 pts. wt. soil conditioner, and water (suitable quantity). The soil conditioner comprises 10-20 pts. wt. clay, 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 sulfate, 2-3 pts. wt. zinc sulfate, 1-2 pts. wt. magnesium chloride, 2-3 pts. wt. ammonium citrate, 1-2 pts. wt. boric acid, 4-6 pts. wt. dipentaerythritol hexaacrylate, 35-40 pts. wt. vinegar solution, 2-3 pts. wt. chitosan, 1-2 pts. wt. Eucalyptus oil, 3-4 pts. wt. N-(2-hydroxypropyl)methacrylamide, 3-4 pts. wt. diatomite, and 2-3 pts. wt. methyltriethoxysilane. The soil conditioner is prepared by uniformly mixing the above-mentioned raw materials except vinegar solution, adding the vinegar solution to mixture, and dispersing obtained mixture at high speed. An INDEPENDENT CLAIM is included for method for preparing the selenium-enriched bioorganic fertilizer which involves (a) mixing ammonium citrate, calcium lignosulfonate, calcium chloride, and charcoal powder, and adding water, and soil conditioner, and continuously stirring and drying mixture, (b) uniformly mixing remaining raw materials except urea, (c) adding products obtained in the steps (a) and (b), and adding urea, and (d) cooling and drying obtained product.
