DETAILED DESCRIPTION - Controlled release fertilizer comprises 50-60 pts. wt. luffa vine, 20-30 pts. wt. quicklime, 80-90 pts. wt. soybean cake, 45-60 pts. wt. soybean, 70-80 pts. wt. dairy manure, 30-40 pts. wt. pond sludge, 10-12 pts. wt. quartz sand, 2-3 pts. wt. biological microbial inoculum, 3-4 pts. wt. ammonium citrate, 8-9 pts. wt. potassium sulfate, 1-12 pts. wt. sodium dihydrogen phosphate, 2-3 pts. wt. sodium selenite, 8-10 pts. wt. ammonium sulfate, 7-9 pts. wt. potassium chloride, 8-12 pts. wt. alkyd resin, 2-3 pts. wt. glycol, 3-4 pts. wt. sodium dodecyl benzene sulfonate, 4-5 pts. wt. cross-linking agent and balanced amount of water. Cross-linking agent comprises 2-3 pts. wt. butyl acrylate, 3-5 pts. wt. tributyl citrate, 2-3 pts. wt. colophony powder, 5-7 pts. wt. green cucumber wood powder, 1-2 pts. wt. N,N'-methylenebisacrylamide, 4-5 pts. wt. ethyl alcohol, 1-2 pts. wt. shellac powder and balanced amount of water, and is prepared by dissolving rosin powder, butyl acrylate, N,N'-methylenebisacrylamide and tributyl citrate in hydro-ethanolic solution at 70-90 degrees C to obtain a solution that is mixed shellac powder, remaining ingredients and water to obtain mixture. The obtained mixture is heated for 20-30 minutes to obtain cross-linking agent. An INDEPENDENT CLAIM is included for a method for preparing controlled release fertilizer, which involves:    (A) drying and crushing luffa vine, quicklime, soybean cake, soybean, dairy manure and pond sludge to obtain powder;    (B) adding biological microbial inoculum with water in obtained powder to obtain a mixture;    (C) fermenting mixture at 40-44 degrees C for 20-26 days;    (D) stirring ammonium sulfate, potassium sulfate, sodium dihydrogen phosphate, sodium selenite, potassium chloride and water to obtain a solution;    (E) adding alkyd resin, sodium dodecyl benzene sulfonate, glycol, cross-linking agent and remaining component to obtain another mixture;    (F) heating mixture for 10-15 minutes;    (G) cooling obtained mixture to obtain solid material;    (H) crushing solid material to obtain resin granule; and    (I) mixing fermented material and resin granule to obtain product.
