NOVELTY - Biological organic fertilizer comprises 60-100 parts weight garden plant waste, 30-40 parts weight soybean meal, 35-40 parts weight rice bran, 20-30 parts weight wheat bran, 10-15 parts weight fish meal, 5-10 parts weight ammonium sulfate, 6-8 parts weight calcium superphosphate, 6-10 parts weight sodium silicate, 10-15 parts weight pearlite, 8-12 parts weight vermiculite, 1-2 parts weight inoculum of engineered microorganism, 10-13 parts weight soil improving agent and remainder water.    USE - As biological organic fertilizer.    ADVANTAGE - The biological organic fertilizer provides energy and nutriment to the crops, and improves fertilizer utilization rate, and yield and quality of the crops.    DETAILED DESCRIPTION - Biological organic fertilizer comprises 60-100 parts weight garden plant waste, 30-40 parts weight soybean meal, 35-40 parts weight rice bran, 20-30 parts weight wheat bran, 10-15 parts weight fish meal, 5-10 parts weight ammonium sulfate, 6-8 parts weight calcium superphosphate, 6-10 parts weight sodium silicate, 10-15 parts weight pearlite, 8-12 parts weight vermiculite, 1-2 parts weight inoculum of engineered microorganism, 10-13 parts weight soil improving agent and remainder water. The soil improving agent comprises 120-130 parts weight weathered coal, 2-3 parts weight ester, 3-4 parts weight jade nanopowder, 1-2 parts weight borax, 1-2 parts weight salicylic acid, 2-3 parts weight calcium carbonate nanoparticle, 2-3 parts weight neopentyl alcohol, 1-2 parts weight triglyceride, 2-3 parts weight sodium selenite, 3-4 parts weight Eucalyptus oil, 4-5 parts weight Mallotus apelta, 3-4 parts weight banana root and remainder water. The soil improving agent is prepared by drying and crushing weathered coal, banana root, borax, salicylic acid and M.apelta, adding water to the crushed materials, heating to 80-90 degrees C, adding ester, jade nanopowder, calcium carbonate nanoparticle and neopentyl alcohol, continuously grinding for 30-40 minutes, then adding triglyceride, sodium selenite and Eucalyptus oil, stirring uniformly, concentrating, granulating, and drying the granules. An INDEPENDENT CLAIM is included for preparation of the above-cited biological organic fertilizer, which involves mixing garden plant waste, soybean meal, rice bran, wheat bran and fish meal, adding inoculum of engineered microorganism, stirring uniformly and fermenting for 15-18 days, then adding ammonium sulfate, calcium superphosphate, sodium silicate, pearlite, vermiculite, soil improving agent and water, stirring uniformly and fermenting for 5-10 days, drying the fermented product and granulating the dried product.
