NOVELTY - Biological organic fertilizer is prepared using 10-15 pts. wt. peanut oil cake, 25-30 pts. wt. pig manure, 4-8 pts. wt. diatomite, 1-2 pts. wt. starch, 10-15 pts. wt. diammonium phosphate, 18-22 pts. wt. potassium chloride, 1-2 pts. wt. effective microorganisms, 10-15 pts. wt. rotten pear, 15-20 pts. wt. rotten oranges, 20-25 pts. wt. mushroom residue, 10-12 pts. wt. silkworm dropping, 2-4 pts. wt. amino acid chelate solution, 8-12 pts. wt. expired milk, 2-4 pts. wt. fructus cnidii, 2-5 pts. wt. tea, 2-4 pts. wt. Eucalyptus, and 1-2 pts. wt. pumpkin vine.    USE - As biological organic fertilizer.    ADVANTAGE - The biological organic fertilizer improves disease resistance and drought resistance of crops, reduces harm to soil, has improved nutrient content as it contains rotten fruit pulp, dried tea residue and peanut oil residue, is cost-effective, enables to convert wastes into useful product, and contains active components that can be easily released and absorbed by crops.    DETAILED DESCRIPTION - Biological organic fertilizer is prepared using 10-15 pts. wt. peanut oil cake, 25-30 pts. wt. pig manure, 4-8 pts. wt. diatomite, 1-2 pts. wt. starch, 10-15 pts. wt. diammonium phosphate, 18-22 pts. wt. potassium chloride, 1-2 pts. wt. effective microorganisms (EM), 10-15 pts. wt. rotten pear, 15-20 pts. wt. rotten oranges, 20-25 pts. wt. mushroom residue, 10-12 pts. wt. silkworm dropping, 2-4 pts. wt. amino acid chelate solution, 8-12 pts. wt. expired milk, 2-4 pts. wt. fructus cnidii, 2-5 pts. wt. dried tea leaves, 2-4 pts. wt. Eucalyptus, and 1-2 pts. wt. pumpkin vine, where the amino acid chelate liquid is prepared by adding 10-15 pts. wt. animal feathers to 25-35% sulfuric acid, hydrolyzing the feathers for 8-10 hours, generating amino acids, adding lime to neutralize, adding 1-2 pts. wt. chitosan and uniformly mixing the components to obtain amino acid chelate liquid, and the dry tea leaves are obtained by drying and sterilizing tea leaves. An INDEPENDENT CLAIM is included for method for producing the biological organic fertilizer, which involves (a) mixing rotten pears and rotten oranges and obtaining rotten fruit pulp, (b) uniformly mixing fructus cnidii, dried tea leaves, Eucalyptus and pumpkin vine, immersing the mixture in vinegar for 2-4 hours, obtaining the mixture, washing the mixture with water and obtaining vinegar pickled plant material, (c) uniformly mixing rotten fruit pulp, vinegar pickled plant material and other raw materials except diammonium phosphate, potassium chloride and amino acid chelate and fermenting the mixture for 10-14 days to obtain fermented material, and (d) grinding and mixing diammonium phosphate and potassium chloride, adding to fermented material and uniformly mixing amino acid chelate liquid to obtain finished product.
