NOVELTY - Organic-inorganic fertilizer comprises municipal solid waste, bird manure, bone powder, gelatin, wood ash, modified diatomite, monoammonium phosphate, urea, mineral slag, potassium chloride, wood sawdust, animal hair, stone-like omphalia, betelnut, oriental wormwood, radix sophorae flavescentis, radix scutellariae, sodium fulvate, carbon, ammonium sulfate, ferrous sulfate, copper sulfate, borax and effective microorganism (EM) strain.    USE - The organic-inorganic fertilizer is used as biological insecticide-fertilizer for tea (claimed).    ADVANTAGE - The insecticide-fertilizer is rich in nitrogen, phosphorus and potassium, easily absorbed by plants and increases the yield, and improves the quality and flavor of tea as nutrient absorption is balanced.    DETAILED DESCRIPTION - Organic-inorganic fertilizer comprises 70-90 pts. wt. municipal solid waste, 10-15 pts. wt. bird manure, 5-8 pts. wt. bone powder, 4-6 pts. wt. gelatin, 20-25 pts. wt. wood ash, 20-25 pts. wt. modified diatomite, 5-10 pts. wt. monoammonium phosphate, 12-15 pts. wt. urea, 12-15 pts. wt. mineral slag, 5-10 pts. wt. potassium chloride, 3-5 pts. wt. wood sawdust, 10-12 pts. wt. animal hair, 3-5 pts. wt. stone-like omphalia, 3-5 pts. wt. betelnut, 3-5 pts. wt. oriental wormwood, 5-8 pts. wt. radix sophorae flavescentis, 3-5 pts. wt. radix scutellariae, 10-15 pts. wt. sodium fulvate, 3-5 pts. wt. carbon, 0.08-0.12 pts. wt. ammonium sulfate, 1.5-2.5 pts. wt. ferrous sulfate, 0.7-1 pts. wt. copper sulfate, 0.8-1.2 pts. wt. borax and 0.1-0.4 pts. wt. effective microorganism (EM) strain. An INDEPENDENT CLAIM is included for preparation of the fertilizer which involves (a) weighing and soaking radix sophorae flavescentis, radix scutellariae, stone-like omphalia, betelnut and oriental wormwood, boiling, extracting and concentrating the extract and recovering the residue, (b) mixing municipal solid waste, bird manure and bone powder with the residue obtained in step (a), crushing and adding sodium fulvate, and mixing uniformly in fermentation tank, (c) adding half the amount of EM strain to the fermentation tank, stirring uniformly and adjusting the humidity and pH of the mixture to 45-46% and 4-6, respectively, (d) fermenting the mixture obtained in step (c) for 3-4 days, and adding remainder EM strain, when the temperature reaches to 50-60 degrees C, stirring uniformly, turning the mixture for every 2-3 days, further fermenting for 8-10 days at controlled temperature of 60-70 degrees C to obtain the fermented product, (e) adding 25-35% hydrochloric acid to animal hair and hydrolyzing for 8-10 hours and adding lime to neutralize the hydrolyzate containing amino acids and adding 3-4 wt.% carboxymethyl cellulose to hydrolyzate, and dissolving ammonium sulfate, ferrous sulfate, copper sulfate and borax in the hydrolyzate to produce a liquid fertilizer, (f) soaking diatomite in 10-15% hydrochloric acid for 3-4 hours, neutralizing the diatomite with 10-12% sodium hydroxide solution and then washing using de-ionized water until it is neutral, adding 2-3% sodium lauryl sulfate, 1-2% peregal, 2-3% tributyl citrate and 3-5% copper sulfate, mixing at high speed of 1000-1200 rotations per minute, drying and grinding into fine powder to obtain modified diatomite, and (g) mixing concentrated liquid obtained in step (a), liquid fertilizer obtained in step (e) and modified diatomite obtained in step (f), stirring and adding monoammonium phosphate, urea, mineral slag, potassium chloride, wood sawdust and gelatin to the fermented product obtained in step (d), mixing the mixture and granulating the product.
