NOVELTY - Organic fertilizer comprises (in parts weight): waste organic matter (44-54), potassium chloride (10-15), humic acid (10-15), medium trace elements (0.4-0.6), microorganisms (0.4-0.6), urea (5-10), calcium superphosphate (5-15) and diammonium phosphate (5-15). The waste organic matter comprises rotten rice husk, dried cake, crop straw, Chinese medicinal herb residue, bamboo-wood fiber, rural domestic waste and other plant wastes. The medium trace element includes calcium, magnesium, sulfur, iron, zinc, boron, manganese, copper, chlorine, molybdenum and nickel.    USE - The organic fertilizer is useful for crops in soil.    ADVANTAGE - The organic fertilizer is rich in phosphorus, improves soil fertility and quality of agricultural products, enhances pest-resistance and drought-resistance of plants, inhibits absorption of harmful substances including heavy metal and pesticide of crops, and purifies and remediates soil.    DETAILED DESCRIPTION - Organic fertilizer comprises (in parts weight): waste organic matter (44-54), potassium chloride (10-15), humic acid (10-15), medium trace elements (0.4-0.6), microorganisms (0.4-0.6), urea (5-10), calcium superphosphate (5-15) and diammonium phosphate (5-15). The waste organic matter comprises rotten rice husk, dried cake, crop straw, Chinese medicinal herb residue, bamboo-wood fiber, rural domestic waste and other plant wastes. The medium trace element includes calcium, magnesium, sulfur, iron, zinc, boron, manganese, copper, chlorine, molybdenum and nickel. The microorganism includes nitrogen-fixing bacteria, Bacillus, Actinomycetes 5406, Saccharomyces, phosphorus-releasing bacteria and potassium-releasing bacteria. An INDEPENDENT CLAIM is included for method of preparing the organic fertilizer, which involves culturing microorganisms in test tube culture and fermentation culture, crushing and screening waste organic matter until the grain diameter reaches size of 0.18 mm, granulating the organic matter waste, potassium chloride, humic acid, secondary micronutrients, microorganisms, carbamide, ammonium nitrate and ammonium chloride to obtain fertilizer.
