NOVELTY - Fertilizer comprises 80-100 pts. wt. wheat bran, 20-30 pts. wt. rice straw, 35-50 pts. wt. rice hull, 7-10 pts. wt. peat soil, 10-12 pts. wt. ammonium hydrogen carbonate, 2-3 pts. wt. microbial inoculants, 10-15 pts. wt. sodium dihydrogen phosphate, 8-14 pts. wt. potassium permanganate, 2-5 pts. wt. humic acid, 4-7 pts. wt. magnesium sulfate, 3-5 pts. wt. additive and water.    USE - The fertilizer is useful for improving soil structure (claimed).    ADVANTAGE - The fertilizer improves soil softness and ventilation and promotes anti-pest effect to plants.    DETAILED DESCRIPTION - Fertilizer comprises 80-100 pts. wt. wheat bran, 20-30 pts. wt. rice straw, 35-50 pts. wt. rice hull, 7-10 pts. wt. peat soil, 10-12 pts. wt. ammonium hydrogen carbonate, 2-3 pts. wt. microbial inoculants, 10-15 pts. wt. sodium dihydrogen phosphate, 8-14 pts. wt. potassium permanganate, 2-5 pts. wt. humic acid, 4-7 pts. wt. magnesium sulfate, 3-5 pts. wt. additive and water. The additive comprises 1-2 pts. wt. sodium dodecyl sulfate, 6-8 pts. wt. medical stone powder, 7-10 pts. wt. acetic acid, 6-9 pts. wt. ethanol, 2-3 pts. wt. N,N-methylenebisacrylamide and 30 pts. wt. water. The additive is prepared by mixing ethanol and water, adding acetic acid and N,N-methylenebisacrylamide to mixture and stirring mixture at speed 150-200 revolutions/minute for 5-10 minutes, mixing sodium dodecyl sulfate and medical stone powder with stirred mixture and stirring mixture at speed 250-400 revolutions/minute for 0.5-1 hour. An INDEPENDENT CLAIM is included for method for preparing fertilizer, which involves (a) crushing rice straw into 3-4 cm filament, adding 2-3 times water and ammonium hydrogen carbonate to rice straw, stirring mixture and allowing to stand at 30-35 degrees C for 14-16 days under environmental condition and filtering mixture and separating residue, (b) processing residue obtained in step (a) in microwave power of 200-250 W for 8-14 minutes, (c) adding water to processed residues, microbial inoculants, wheat bran, rice hull and peat soil and mixing, where the mixture moisture content is 60%, fermenting mixture for 8-12 days, and (d) crushing fermented mixture, mixing the powder with remaining raw materials and granulating mixture, where the mixture moisture content is 20%.
