NOVELTY - A fertilizer includes 10-20 pts.wt. Camellia, 20-25 pts.wt. ammonium dihydrogen phosphate, 18-22 pts.wt. potassium chloride, 20-30 pts.wt. bentonite, 10-12 pts.wt. attapulgite, 5-7 pts.wt. lignite, 3-4 pts.wt. neem leaf powder, 3-4 pts.wt. wolfsbane powder, 10-15 pts.wt. sugar cane bagasse, 10-15 pts.wt. potassium feldspar, 18-22 pts.wt. livestock manure, 15-20 pts.wt. of 30% sulfuric acid, 5-10 pts.wt. lime, 10-15 pts.wt. bone powder, and 1-2 pts.wt. liquid paraffin.    USE - A fertilizer for corn base (claimed).    ADVANTAGE - The fertilizer has improved utilization rate, has slow release effect, has reduced fertilizing amount, reduces pesticide residue, and improves yield and quality of the corn.    DETAILED DESCRIPTION - A fertilizer comprises 10-20 pts.wt. Camellia, 5-6 pts.wt. urea, 20-25 pts.wt. ammonium dihydrogen phosphate, 18-22 pts.wt. potassium chloride, 20-30 pts.wt. bentonite, 0.2-0.5 pts.wt. ferrous sulfate, 1-2 pts.wt. zinc sulfate, 0.1-0.3 pts.wt. ammonium molybdate, 10-12 pts.wt. attapulgite, 5-7 pts.wt. lignite, 3-4 pts.wt. neem leaf powder, 3-4 pts.wt. wolfsbane powder, 10-15 pts.wt. sugar cane bagasse, 10-15 pts.wt. potassium feldspar, 18-22 pts.wt. livestock manure, 3-4 pts.wt. carboxymethyl cellulose, 15-20 pts.wt. of 30% sulfuric acid, 5-10 pts.wt. lime, 10-15 pts.wt. bone powder, and 1-2 pts.wt. liquid paraffin. An INDEPENDENT CLAIM is included for preparing the fertilizer, comprising adding bone powder into 30% sulfuric acid, carrying out hydrolysis at 100-110 degrees C for 1-2 hours to generate amino acid, adding lime to neutralize the pH value at 6-6.8, adding carboxymethyl cellulose, ferrous sulfate, zinc sulfate, and ammonium molybdate, dissolving, and reacting at 90-105 degrees C for 5-6 hours to generate an amino acid chelated fertilizer solution; sintering potassium feldspar at 400-500 degrees C for 6-8 hours, adding 1-2% liquid paraffin into a nanopowder, and mixing with bentonite; uniformly mixing oil tea cake, sugar cane bagasse, poultry Bacillus subtilis, piling for 5-10 days, fermenting at 60-65 degrees C for 30-40 days, and standing; mixing urea, monoammonium phosphate, and coated potassium chloride, crushing with attapulgite, lignite, fermented organic fertilizer, and passing at 100-200 mesh sieve; uniformly mixing neem leaf powder and wolfsbane powder; and uniformly mixing amino acid chelated fertilizer solution, granulating, and spraying liquid to coat film.
