NOVELTY - Fertilizer comprises tobacco powder, potassium sulfate, straw, potassium dihydrogen phosphate, Trichoderma harzianum, copper sulfate, perlite, oyster shell, attapulgite, ammonium molybdate, chicken manure, wild buckwheat rhizome, silicate bacteria inoculant, wollastonite, and auxiliary material. The auxiliary material contains iron ore powder, fresh konjac, magnesium amino acid chelate, amino acid chelated copper, amino acid chelated boron, manganese amino acid chelate, methyl methacrylate, N-butyl thiophosphoric triamide, fresh grass, and coral rock.    USE - The fertilizer is useful for crops.    ADVANTAGE - The fertilizer is rich in nutrients, environmentally-friendly, converts agricultural waste into valuable resource, and contains no residue.    DETAILED DESCRIPTION - Fertilizer comprises 4-7 pts. wt. tobacco powder, 3-5 pts. wt. potassium sulfate, 40-60 pts. wt. straw, 5-8 pts. wt. potassium dihydrogen phosphate, 2-3 pts. wt. Trichoderma harzianum, 3-5 pts. wt. copper sulfate, 4-6 pts. wt. perlite, 5-6 pts. wt. oyster shell, 6-8 pts. wt. attapulgite, 1-2 pts. wt. ammonium molybdate, 120-140 pts. wt. chicken manure, 5-8 pts. wt. wild buckwheat rhizome, 2-4 pts. wt. silicate bacteria inoculant, 4-7 pts. wt. wollastonite, and 5-7 pts. wt. auxiliary material. The auxiliary material comprises 4-6 pts. wt. iron ore powder, 3-6 pts. wt. ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid) (EDDHA) chelated iron, 8-10 pts. wt. fresh konjac, 3-4 pts. wt. magnesium amino acid chelate, 3-4 pts. wt. amino acid chelated copper, 3-4 pts. wt. amino acid chelated boron, 3-4 pts. wt. manganese amino acid chelate, 1-3 pts. wt. methyl methacrylate, 0.1-0.2 pt. wt. N-butyl thiophosphoric triamide, 12-16 pts. wt. fresh grass, and 8-12 pts. wt. coral rock. The auxiliary material is prepared by washing fresh konjac, and fresh grass using water, placing the washed konjac and grass in mortar, grinding the washed materials for 20-40 minutes, filtering the ground materials, collecting filtered liquid, crushing coral rock and iron ore powder into fine powder, adding the remaining materials except methyl methacrylate and N-butyl thiophosphoric triamide to the filtered liquid, uniformly stirring the mixture, granulating the mixture into spherical particle of 2-4 mm in diameter, coating spherical particle with methyl methacrylate and N-butyl thiophosphoric triamide, and drying the coated particle. An INDEPENDENT CLAIM is included for method for preparing fertilizer, which involves (a) placing chicken manure, tobacco powder, and T.harzianum into fermentation pool, adding suitable quantity of water, inoculating 0.5 wt.% effective microorganism (EM), performing anaerobic fermentation for 7-11 days, maintaining 40% water content, and deep turning the mixture once, (b) adding attapulgite, straw, golden buckwheat rhizome, and 0.3 wt.% Bacillus subtilis microbial inoculums to the fermentation pool, performing aerobic fermentation at 40-55 degrees C for 60-72 hours, maintaining the water content to 50%, adding 0.2 wt.% Aspergillus niger, continuously fermenting for 19-21 days, and drying the fermented material, (c) adding perlite, wollastonite, and oyster shell, sterilizing 1.05 kg/cm2 mixture for 60-90 minutes, and grinding the sterilized mixture into fine powder, and (d) combining and uniformly mixing fermented mixture obtained in step (b), resulting mixture obtained in step (c), silicate bacteria inoculants, potassium dihydrogen phosphate, potassium sulfate, ammonium molybdate, copper sulfate, and auxiliary materials, adding 0.8 wt.% earth material as binder, uniformly stirring the mixture, granulating the mixture into spherical particle of 8-12 mm in diameter, and drying at low temperature.
