NOVELTY - A bio-organic fertilizer comprises dry chicken manure, castor bean shell, peanut shell, cottonseed hulls, xylitol residue, castor bean meal, apple pomace, biogas residue, peat, shell powder, urea, potassium sulfate, ammonium chloride, zinc sulfate, ammonium molybdate, cerium ammonium nitrate, Effective Microorganisms microbial inoculum, coating agent, and water.    USE - Bio-organic fertilizer.    ADVANTAGE - The fertilizer has rational formulation, balanced nutrition, improves plant growth and soil fertility, prolongs fertilizer effect, and improves crop yield.    DETAILED DESCRIPTION - A bio-organic fertilizer comprises 100-120 pts. wt. dry chicken manure, 40-45 pts. wt. castor bean shell, 10-12 pts. wt. peanut shell, 30-34 pts. wt. cottonseed hulls, 20-24 pts. wt. xylitol residue, 10-12 pts. wt. castor bean meal, 30-34 pts. wt. apple pomace, 20-23 pts. wt. biogas residue, 20-23 pts. wt. peat, 10-12 pts. wt. shell powder, 50-55 pts. wt. urea, 30-34 pts. wt. potassium sulfate, 24-28 pts. wt. ammonium chloride, 12-14 pts. wt. zinc sulfate, 6-8 pts. wt. ammonium molybdate, 2-3 pts. wt. cerium ammonium nitrate, 3-4 pts. wt. Effective Microorganisms microbial inoculum, 4-6 pts. wt. coating agent, and balance water. Coating agent comprises 50-60 pts. wt. polyurethane acrylate, 20-30 pts. wt. ethyl acrylate, 20-22 pts. wt. chlorinated paraffin, 1-2 pts. wt. crosslinker TAC, 0.1-0.2 pt. wt. nanocarbon, 1-2 pts. wt. medical stone powder, and 3-4 pts. wt. Kandy-Garrison-Akers propylene glycol. An INDEPENDENT CLAIM is included for preparation of bio-organic fertilizer comprising taking castor bean shell, peanut shell and cottonseed hulls, adding water to soak for 20-24 hours, adding Effective Microorganisms microbial inoculum, stirring uniformly to ferment for 15-20 days at low temperature, turning over every 4-5 days, grinding into slurry, adding shell powder, xylitol residue and apple pomace, sealing to ferment for 15-20 days, turning over every 5-6 days, adding urea, potassium sulfate, ammonium chloride and zinc sulfate, heating, adding remaining raw materials, and stirring to completely dissolve.
