NOVELTY - Biomass coal soybean special coated slow release fertilizer comprises wheat straw, peanut shell, soybean rhizobium microbial inoculum, resin raw solid nitrogen fungus, azotobacter chroococcum microbial inoculum, soybean, ammonium bicarbonate, potassium nitrate, zinc sulfate, magnesium sulfate, phosphatic fertilizer, binder and water. The binder comprises polyvinyl alcohol, limestone powder, coal tar, sodium bicarbonate, chitin, dodecylbenzene sulfonate, tributyl phosphate, ethanol and water.    USE - Biomass coal soybean special coated slow release fertilizer.    ADVANTAGE - The fertilizer saves cost.    DETAILED DESCRIPTION - Biomass coal soybean special coated slow release fertilizer comprises 10-15 pts. wt. wheat straw, 20-24 pts. wt. peanut shell, 2-5 pts. wt. soybean rhizobium microbial inoculum, 3-6 pts. wt. resin raw solid nitrogen fungus, 2-3 pts. wt. azotobacter chroococcum microbial inoculum, 30-40 pts. wt. soybean, 20-26 pts. wt. ammonium bicarbonate, 20-25 pts. wt. potassium nitrate, 4-7 pts. wt. zinc sulfate, 5-8 pts. wt. magnesium sulfate, 10-18 pts. wt. phosphatic fertilizer, 5-7 pts. wt. binder and water. The binder comprises 10-15 pts. wt. polyvinyl alcohol, 3-5 pts. wt. limestone powder, 4-7 pts. wt. coal tar, 1-2 pts. wt. sodium bicarbonate, 2-4 pts. wt. chitin, 1-2.58 pts. wt. dodecylbenzene sulfonate, 0.5-1 pt. wt. tributyl phosphate, 6-10 pts. wt. ethanol and 50 pts. wt. water. The preparation of binder comprises mixing ethanol and water, adding coal tar, dodecylbenzene sulfonate, sodium bicarbonate and tributyl phosphate, heating to 70-80wt.%, stirring at 350-600 revolutions/minute for 30-40 minutes, standing for 20 minutes until foam disappear, adding polyvinyl alcohol, limestone powder and chitin, and stirring at 60-75 degrees C. An INDEPENDENT CLAIM is included for preparation of biomass coal soybean special coated slow release fertilizer comprising mixing walnut and peanut shell, adding 2-3 times water, oscillating for 8-10 hours, ball milling for 20-30 minutes, mixing, drying to obtain powder, putting in carbonization furnace under sealing condition, carbonizing at 600-800 degrees C for 6-8 hours, cooling to room temperature to obtain carbonized powders; mixing soybean rhizobium microbial inoculum raw resin solid nitrogen fungus microbial inoculum, azotobacter chroococcum microbial inoculum and soybean curd residue, adding water, stirring into paste material, oscillating at constant temperature of 30-35 degrees C, culturing for 4-6 days, drying and crushing to powders; mixing ammonium hydrogen carbonate, potassium nitrate, zinc sulfate, magnesium sulfate, phosphatic fertilizer and other components, crushing to 40 meshes powders, adding Carbonized powders, adding water to adjust water content to 40%; and adding binder and water to adjust water content to 70-80%, preheating to 80-90 degrees C, repeating for 2-3 times, and hot air is drying.
