USE - As coated fertilizer.    ADVANTAGE - The coated fertilizer improves soil permeability, and yield of plants, and promotes nutrient absorption ability of plants.    DETAILED DESCRIPTION - Coated fertilizer comprises 35-38 pts. wt. pine bark, 60-64 pts. wt. banana peel, 65-68 pts. wt. orange peel, 34-38 pts. wt. bran, 6-8 pts. wt. effective microorganism, 10-13 pts. wt. liquid paraffin, 20-24 pts. wt. urea, 9-11 pts. wt. sepiolite powder, 7-9 pts. wt. dolomite powder, 15-19 pts. wt. potassium sulfate, 18-21 pts. wt. potassium dihydrogen phosphate, 2-3 pts. wt. ferrous sulfate, 7-9 pts. wt. soil improving agent, and water (suitable quantity). The soil improving agent comprises 10-20 pts. wt. coal powder, 1-2 pts. wt. nanocarbon powder, 4-5 pts. wt. polymeric ferric sulfate, 17-19 pts. wt. pentaerythritol triacrylate, 3-4 pts. wt. selenium yeast, 2-3 pts. wt. copper sulfate, 2-3 pts. wt. zinc gluconate, 1-2 pts. wt. medical stone powder, 2-3 pts. wt. ammonium sulfate, 1-2 pts. wt. boric acid, 4-6 pts. wt. dipentaerythritol hexaacrylate, 30-40 pts. wt. vinegar, 2-3 pts. wt. chitosan, 1-2 pts. wt. Eucalyptus oil, 2-3 pts. wt. sodium tripolyphosphate, and 1-2 pts. wt. ascorbic acid. The soil improving agent is prepared by uniformly mixing pentaerythritol triacrylate, dipentaerythritol hexaacrylate, coal powder, nanocarbon powder, and Eucalyptus oil, heating mixture at 65-75 degrees C, and adding remaining raw materials, and uniformly mixing obtained product. An INDEPENDENT CLAIM is included for method for preparing the coated fertilizer, which involves (a) uniformly mixing potassium sulfate, potassium dihydrogen phosphate, and ferrous sulfate, and adding water, adding soil improving agent, sepiolite powder, and dolomite powder to mixture, uniformly stirring mixture, and drying stirred mixture, (b) uniformly mixing remaining raw materials except urea, and performing fermentation for 22-30 days, and (c) heating urea, and adding products obtained in the steps (a) and (b), and drying obtained mixture.
