NOVELTY - High-efficiency liquid fertilizer comprises 53-57 pts. wt. cereal bran, 6-9 pts. wt. sulfur-ammonium nitrate, 40-44 pts. wt. sesame cake, 2-4 pts. wt. zinc sulfate, 6-7 pts. wt. lactic acid, 20-25 pts. wt. pepper seeds, 125-135 pts. wt. livestock and poultry feathers, 4-6 pts. wt. copper sulfate, 5-7 pts. wt. ferrous sulfate, 3-6 pts. wt. genetically modified microbial agent, and balance amount of water.    USE - High-efficiency liquid fertilizer (claimed).    ADVANTAGE - The liquid fertilizer has high efficiency, excellent complexing ability and denitrification effect and is rich in nutrition content and mineral elements, reduces nitrogen volatilization, and improves nutrient utilization rate in crops.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of high-efficiency liquid fertilizer involving taking livestock and poultry feathers and then washing, drying the feathers and then crushing, adding 3 mol/l sulfuric acid solution to the crushed feathers, uniformly mixing, placing the mixture in a microwave oven and then hydrolyzing for 220-260 minutes, adding 6 mol/l potassium hydroxide solution to the mixture and then placing in a microwave oven, hydrolyzing the mixture for 260-300 minutes to obtain a hydrolysis liquid and then stirring, filtering the mixture to obtain a supernatant and then cleaning organic residues, adding lactic acid and copper sulfate to the mixture and then adjusting pH value to 6, heating the mixture at 50-60 degrees C and then reacting for 70-90 minutes, adding ferrous sulfate to the mixture and then reacting, increasing the temperature at 65-70 degrees C for 40-60 minutes to obtain a composite amino acid chelate solution, adding pepper seeds, cereal bran and sesame cake to the composite amino acid chelate solution and then placing in a fermentation tank, adding water to the mixture and then fermenting under a moisture content of 45-55%, composting the mixture for 35-55 days, adding 8-10 pts. wt. water and genetically modified microbial agent to the mixture and then stirring, placing the mixture in a sealed container and then fermenting for 6-8 days, filtering the mixture and then anaerobically composting, adding zinc sulfate, sulfur-ammonium nitrate and remaining raw materials to the mixture and then uniformly mixing, placing the mixture in a magnetic machine, and magnetizing for 8-10 minutes.
