NOVELTY - Straw fermented organic fertilizer comprises rice straw, wheat straw, quartz sand, corncob, humus, effective microorganisms (EM) containing liquid, sweet potato residues, camphor leaves, attapulgite, carrageenan, potash fertilizer, ammonium dihydrogen phosphate, calcium chloride, sodium bisulfite, film coating agent, and water. The film coating agent comprises dodecyldimethylamine oxide, alkyd resin, turpentine oil, gypsum powder, ethanol, calcium stearate, potassium oxide, ferric chloride, iron ore powder and water.    USE - As straw fermented organic fertilizer.    ADVANTAGE - The organic fertilizer contains appropriate nitrogen-phosphorus-potassium (NPK) content, and rich amount of nitrogen, phosphorus, potassium, calcium, magnesium and organic substances, reduces usage of chemical fertilizers and is prepared by fermentation of biologically versatile renewable resources including crop stalks and mixed organic minerals, and hence is environmentally-friendly, and favorable to resources and human health, and provides maximized fertilization efficiency to plants, as the fertilizer contains coated granules that on contact with soil enable slow-release of soil improvement component which is present on outer surface of the granules firstly, and then active components present internally exhibit their functions directly inside the plants in improved manner.    DETAILED DESCRIPTION - Straw fermented organic fertilizer comprises 20-30 pts. wt. rice straw, 60-70 pts. wt. wheat straw, 5-10 pts. wt. quartz sand, 30-45 pts. wt. corncob, 10-15 pts. wt. humus, 2-3 pts. wt. effective microorganisms (EM) containing liquid, 10-15 pts. wt. sweet potato residues, 20-25 pts. wt. camphor leaves, 20-30 pts. wt. attapulgite, 10-14 pts. wt. carrageenan, 7-10 pts. wt. potash fertilizer, 8-10 pts. wt. ammonium dihydrogen phosphate, 4-6 pts. wt. calcium chloride, 3-5 pts. wt. sodium bisulfite, 3-5 pts. wt. film coating agent, and water (suitable quantity). The film coating agent comprises 2.5-3 pts. wt. dodecyldimethylamine oxide, 10-12 pts. wt. alkyd resin, 4-6 pts. wt. turpentine oil, 2-3.5 pts. wt. gypsum powder, 8-10 pts. wt. ethanol, 3-5 pts. wt. calcium stearate, 4-6 pts. wt. potassium oxide, 4.5-6 pts. wt. ferric chloride, 1-2 pts. wt. iron ore powder, and water (suitable quantity). Preparation method of the film coating agent, involves mixing ethanol and turpentine oil, diluting obtained mixed solution with water, where water is added in an amount which is 3 times with respect to total amount of the mixed solution, adding dodecyldimethylamine oxide, alkyd resin, calcium stearate, potassium oxide, ferric chloride and iron ore powder (half amount) to diluted solution, heating and stirring the solution for 40-50 minutes, adding crushed gypsum powder and iron ore powder (remaining half amount) of more than 180 mesh size to obtained hot solution, and stirring mixture to obtain emulsion. An INDEPENDENT CLAIM is included for preparation method of the above-mentioned straw fermented organic fertilizer, which involves (a) mixing rice straw, wheat straw, corncob and camphor leaves, crushing obtained mixture, adding sweet potato residues and EM containing liquid diluted up to 10 times with water to obtained crushed product, adjusting water content of obtained mixture to 40%, and fermenting the mixture at 38-42 degrees C for 18-20 days, where fermenting mixture is stirred once every 2 days, (b) mixing potash fertilizer, ammonium dihydrogen phosphate, calcium chloride and sodium bisulfite, adding water to obtained mixture in an amount which is 4 times with respect to total weight of the mixture, heating and stirring the mixture for 20-30 minutes, mixing quartz sand with stirred mixture, adding obtained mixture to fermented product obtained in the step (a), and homogenizing mixture, (c) subjecting homogenized product to dry granulation process, adding dried fertilizer granules to coating machine, spraying film coating agent onto surface of dried fertilizer granules at 70-80 degrees C under constant moving condition, and drying film coated fertilizer granules under hot air for 10-15 minutes, and (d) mixing humus, attapulgite, carrageenan and other remaining material, adding water to obtained mixture, further coating surface of dried film coated granules uniformly with obtained paste, and drying coated fertilizer granules.
