NOVELTY - Biological fertilizer comprises peat, clay, complex microbial inoculant, polyacrylamide, ammonium sulfate, potassium dihydrogen phosphate, calcium chloride, borax, zinc sulfate, acetic acid, glycerin, sodium gluconate, oyster shell powder and soil conditioner. The soil conditioner comprises sepiolite powder, dodecyl ester, nano-jade powder, soapstock, ascorbic acid, magnesium sulfate, lentinan, phenyltrimethoxysilane, manganese carbonate, ferrous sulfate and water.    USE - As biological fertilizer.    ADVANTAGE - The biological fertilizer improves soil structure, is easily absorbed by crops, reduces absorption of heavy metal element by crops as it does not contain toxic heavy metal elements, increases crop yield and quality, and can supplement nitrogen, phosphorus and potassium to the soil.    DETAILED DESCRIPTION - Biological fertilizer comprises 200-350 pts. wt. peat, 100-150 pts. wt. clay, 5-10 pts. wt. complex microbial inoculant, 5-7 pts. wt. polyacrylamide, 60-80 pts. wt. ammonium sulfate, 50-65 pts. wt. potassium dihydrogen phosphate, 70-80 pts. wt. calcium chloride, 20-25 pts. wt. borax, 15-25 pts. wt. zinc sulfate, 20-25 pts. wt. acetic acid, 2-3 pts. wt. glycerin, 6-10 pts. wt. sodium gluconate, 80-100 pts. wt. oyster shell powder and 9-12 pts. wt. soil conditioner. The soil conditioner comprises 110-120 pts. wt. sepiolite powder, 3-4 pts. wt. alcohol ester 12, 4-5 pts. wt. nano-jade powder, 3-4 pts. wt. soapstock, 2-3 pts. wt. ascorbic acid, 3-4 pts. wt. magnesium sulfate, 1-2 pts. wt. lentinan, 3-4 pts. wt. phenyltrimethoxysilane, 3-4 pts. wt. manganese carbonate, 5-6 pts. wt. ferrous sulfate and water (suitable quantity). The soil conditioner is prepared by taking the sepiolite powder, nano-jade powder and soapstock, adding water, grinding into slurry, heating at 70-75 degrees C, adding the ascorbic acid, magnesium sulfate, lentinan and phenyltriethoxysilane, continuously grinding for 30-45 minutes, drying, finally adding the remaining raw materials, mixing uniformly, granulating, and obtaining product. The complex microbial inoculant comprises 0.5x 10-1.5x 10 colony forming unit (cfu)/g Bacillus licheniformis, 0.2x 10-0.8x 10 cfu/g B.pumilus, 0.2x 10-0.8x 10 cfu/g B.laterosporus, 0.5x 10-1.5x 10 cfu/g B.megaterium and 0.5x 10-1.5x 10 cfu/g silicate bacteria. The complex microbial inoculant is obtained by taking slant culture of the above-mentioned microorganisms, inoculating in a culture medium, performing shake culture, fermenting, drying and mixing and to obtain product.
