Bacillus subtilis, 0.1-0.2 pts. wt. Aspergillus oryzae, 0.1-0.2 pts. wt. Saccharomyces cerevisiae, 3-6 pts. wt. pomegranate rind, 2-4 pts. wt. neem, 5-7 pts. wt. spora lygodii, 5-7 pts. wt. betel nut, 3-6 pts. wt. copper sulfate, 12-14 pts. wt. potassium sulfate, 12-14 pts. wt. ammonium hydrogen carbonate, 10-12 pts. wt. calcium superphosphate and 10-14 pts. wt. urea.    USE - As biological fertilizer used as insecticide (claimed).    ADVANTAGE - The biological fertilizer has improved water quality and delays development of disease resistance.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method of preparing the biological fertilizer which involves (a) soaking pomegranate rind, neem, spora lygodii and betel nut, extracting soaked materials and concentrating the extract obtain Chinese medicinal herbal solution and recovering medicinal residue; (b) adding chicken manure, waste material, straw powder, fruit residue and bone powder to the medicinal residue obtained in step (a) into a mixer and mixing to obtain a mixture; (c) inoculating B.subtilis, A.oryzae and S.cerevisiae to the mixture obtained in step (b), where the mixture has water content of 45-55% and pH of 4-6; (d) stacking the mixture obtained in step (c) and carrying out aerobic fermentation of obtained stack; (e) adding calcium superphosphate to the mixture obtained in step (d), where the mixture turns once for the first time after 2 days of fermentation; (f) adding urea to the mixture obtained in step (e) when the obtained mixture turns for the second time; (g) stacking the mixture obtained in step (f) and fermenting the obtained stack at 50-60 degrees C for 18-24 days, where the obtained mixture turns after every 2-3 days and maintaining the temperature of the obtained mixture at 60-70 degrees C and stopping fermentation; and (h) adding copper sulfate, potassium sulfate and ammonium hydrogen carbonate to the mixture obtained in step (g), where the mixture has moisture content of less than 25%, screening and granulating the obtained mixture and spraying and coating product.
