NOVELTY - Organic fertilizer comprises rotten bark, cottonseed hulls, peanut shell, dry cow dung, dry sludge, zeolite powder, biological microbial inoculum, calcium hydrophosphate, sodium humate, fulvic acid, manganese sulfate, ferrous sulfate, urea, auxiliary agent and water. The biological microbial inoculum comprises Bacillus licheniformis and Acidithiobacillus thiooxidans. The auxiliary agent includes dimethylpropane carboxylate, sodium carboxymethyl cellulose, epoxy chloropropane, dimethyl silicone oil, nano-carbon, diethylaminoethyl alcohol, coal ash and ammonium chloride.    USE - Organic fertilizer used for growing tomato (claimed).    ADVANTAGE - The organic fertilizer contains nitrogen, phosphorus, and potassium, which are suitable for plant growth.    DETAILED DESCRIPTION - Organic fertilizer comprises 10-15 pts. wt. rotten bark, 6-8 pts. wt. cottonseed hulls, 8-10 pts. wt. peanut shell, 6-10 pts. wt. dry cow dung, 16-20 pts. wt. dry sludge, 4-6 pts. wt. zeolite powder, 0.05-0.08 pt. wt. biological microbial inoculum, 1-2 pts. wt. calcium hydrophosphate, 0.2-0.4 pt. wt. sodium humate, 0.1-0.3 pt. wt. fulvic acid, 0.04-0.06 pt. wt. manganese sulfate, 0.02-0.05 pt. wt. ferrous sulfate, 2-3 pts. wt. urea, 0.4-0.5 pt. wt. auxiliary agent and water. The biological microbial inoculum comprises Bacillus licheniformis and Acidithiobacillus thiooxidans at 1:1 ratio. The auxiliary agent comprises 1-2 pts. wt. dimethylpropane carboxylate, 0.2-0.5 pt. wt. sodium carboxymethyl cellulose, 0.3-0.8 pt. wt. epoxy chloropropane, 2-3 pts. wt. dimethyl silicone oil, 10-12 pts. wt. nano-carbon, 0.8-1.2 pts. wt. diethylaminoethyl alcohol, 13-16 pts. wt. coal ash, 1.5-2 pts. wt. ammonium chloride and water. It is prepared by adding diethylaminoethyl alcohol in 1-12 times by volume of water, mixing, adding dimethylpropane carboxylate, sodium carboxymethyl cellulose, epoxy chloropropane, dimethyl silicone oil and ammonium chloride, heating at 60-80 degrees C, stirring for 10-15 minutes, adding nano-carbon and coal ash, preparing into paste, drying and crushing to obtain the product. An INDEPENDENT CLAIM is included for preparation of organic fertilizer including mixing rotten bark, cottonseed hulls and peanut shell, adding equal volume of water, boiling for 20-30 minutes, soaking for 5-6 hours, filtering, adding dry cow dung and zeolite powder, grinding, mixing crushed dry sludge to obtain mixture A, diluting biological microbial inoculum with water at 1:10-12 ratio, spraying on mixture A, uniformly mixing, maintaining the temperature at 35-40 degrees C, fermenting for 12-18 days to obtain fermented material, mixing calcium hydrophosphate, sodium humate, fulvic acid, manganese sulfate, ferrous sulfate, urea, other auxiliary agents and the rest components, adding 8-12 times (based on total weight) water, ultrasonically processing at 0.4-0.8 W/cm2, dissolving by stirring for 30-40 minutes, spraying on fermented material, mechanically rolling while stirring, drying, adjusting the water content at less than or equal to 20%, ultra-micro-crushing by 200-mesh sieve, granulating, and packaging.
