DETAILED DESCRIPTION - Coated fertilizer composition comprises 32-36 pts. wt. colza cake, 30-34 pts. wt. loose scale, 3-5 pts. wt. pearlite, 15-18 pts. wt. urea, 8-14 pts. wt. chitin, 1-2 pts. wt. Borax (RTM: Sodium tetraborate), 0.4-0.7 pts. wt. zinc oxide, 23-27 pts. wt. corn straw, 43-48 pts. wt. dairy manure, 2-3 pts. wt. calcium magnesium phosphate fertilizer, 12-17 pts. wt. potassium dihydrogen phosphate, 2-4 pts. wt. ethylenediamine tetraacetic acid, 0.4-1.0 pts. wt. rare earth nitrate, 0.3-0.8 pts. wt. manganese sulfate, 0.1-0.3 pts. wt. zirconium oxide, 0.2-0.6 pts. wt. ferrous sulfate, 7-9 pts. wt. effective micro-organism, 7-9 pts. wt. soil improving agent and balanced amount of water, where soil improving agent is composed of 3-6 pts. wt. microsilica, 30-36 pts. wt. peat, 4-6 pts. wt. ethylene glycol dimethacrylate, 15-18 pts. wt. bentonite, 2-3 pts. wt. sulfur, 1-2 pts. wt. polymeric ferric sulfate, 0.3-0.8 pts. wt. Borax (RTM: Sodium tetraborate), 0.5-1.0 pts. wt. selenium yeast, 0.2-0.6 pts. wt. copper sulfate, 0.5-1.0 pts. wt. zinc acetate, 0.2-0.4 pts. wt. calcium silicate, 0.02-0.05 pts. wt. solubilizing bacteria, 0.02-0.05 pts. wt. potassium solubilizing bacteria, 0.2-0.5 pts. wt. sodium dodecyl benzene sulfonate, 2-3 pts. wt. hydroxypropyl cellulose, 0.5-1.0 pts. wt. sodium alginate, 0.3-0.5 pts. wt. polyethylene glycol and 0.2-0.5 pts. wt. glycerol. The soil improving agent is prepared by mixing peat, ethylene glycol dimethacrylate, bentonite, Borax, selenium yeast, copper sulfate, zinc acetate and calcium silicate, and then grinding them into fine powder. The obtained powder is mixed with polymeric ferric sulfate, microsilica, solubilizing bacteria and potassium solubilizing bacteria uniformly, and then the obtained material is ground and dispersed. The obtained material is mixed with sodium dodecyl benzene sulfonate and sodium alginate, and then the obtained material is dried by using fluidized bed drier. The obtained material is mixed with hydroxypropyl cellulose, water polyethylene glycol and glycerol with stirring. The obtained material is dried by using fluidized bed drier, and then atomized them. The obtained material is cooled at normal temperature to obtain the soil improving agent. An INDEPENDENT CLAIM is included for a method for preparing a coated fertilizer composition, which involves:    (A) mixing colza cake, loose scale, corn straw, dairy manure and effective micro-organism, and maintaining 43-46 % moisture content;    (B) fermenting the obtained mixtures at normal temperature in anaerobic condition for 24-27 days, where the material is turned once per 3-4 days;    (C) drying the obtained material, and then crushing and granulating them;    (D) dissolving rare earth nitrate, ferrous sulfate, zirconium oxide, zinc oxide, Borax, manganese sulfate and ethylenediamine tetracetic acid in 5-10 vol.% sulfuric acid, and then adding monopotassium phosphate, urea, perlite and calcium-magnesium phosphate fertilizer to the obtained material;    (E) granulating the obtained material;    (F) rolling ladle to clothes at 40-50 degrees C, and then the putting chitin in coating pan;    (G) atomizing and spraying the obtained granules continuously for uniform coating;    (H) drying the obtained material at 50-60 degrees C by using hot air dryer, and then cooling then to room temperature; and    (I) mixing soil modifying agent to the obtained material to obtain the finished product.
