NOVELTY - An environment-friendly liquid fertilizer comprises 42-46 pts. wt. traditional Chinese medicine slag, 6-8 pts. wt. ammonium sulfate, 4-6 pts. wt. malic acid, 26-29 pts. wt. cake, 55-65 pts. wt. wheat bran, 7-10 pts. wt. calcium superphosphate, 95-105 pts. wt. waste livestock and poultry feather, 4-5 pts. wt. copper sulfate, 4-5 pts. wt. ferrous sulfate, 6-7 pts. wt. GM microorganism, and balance water.    USE - Environment-friendly liquid fertilizer.    ADVANTAGE - The environment-friendly liquid fertilizer contains lots of organic humic acid which increases soil organic matter content when used for a long time, greatly improves adsorption capacity of soil, controls and degrades pesticide residues in soil, purifies soil environment, and fully meets the needs of crops.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of environment-friendly liquid fertilizer comprising:    (A) washing waste livestock and poultry feather, drying, crushing, dividing into two equal parts, adding first part with 10 times 3 mol/L sulfuric acid solution, microwave hydrolyzing for 200-230 minutes, adding second part with 10 times 6 mol/L potassium hydroxide solution, and microwave hydrolyzing for 250-280 minutes;    (B) mixing two hydrolyzates, stirring, filtering to obtain supernatant and organic residue, adding supernatant with malic acid and copper sulfate, adjusting pH to 6, heating to 55-65 degrees C for 70-80 minutes, adding ferrous sulfate, and heating to 70-80 degrees C for 40-50 minutes to obtain composite amino acid chelate solution;    (C) adding organic residue with cake and wheat bran, mixing, adding into fermentation tank, mixing with water until water content is 45-55%, and fermenting for 30-50 days;    (D) adding fermentation product with 8-10 times water and GM microorganism, stirring, placing into sealed container for 7-8 days, and filtering through double gauze filter to obtain anaerobic compost extract; and    (E) adding with composite amino acid chelate solution and remaining raw materials, stirring, and subjecting to magnetization at 400-500 mT field for 7-9 minutes through strong magnetic machine.
