NOVELTY - Sustained release organic fertilizer comprises pig manure (35-45 pts. wt.), humic acid (4-6 pts. wt.), watermelon vine seedlings (6-8 pts. wt.), superphosphate (4-6 pts. wt.), monoammonium phosphate (4-6 pts. wt.), carbamide (6-10 pts. wt.), bone meal (12-16 pts. wt.), diammonium phosphate (4-5 pts. wt.), zinc sulfate (3-4 pts. wt.), borax (3-4 pts. wt.), magnesium sulfate (2-3 pts. wt.), crop stalk (25-35 pts. wt.), silkworm excrement (20-30 pts. wt.), eggshell powder (5-7 pts. wt.), soil additive (18-24 pts. wt.), and balanced amount of water.    USE - Sustained release organic fertilizer used for apricot (claimed).    ADVANTAGE - The sustained release organic fertilizer is cost-effective and suitable for industrial production.    DETAILED DESCRIPTION - Sustained release organic fertilizer comprises pig manure (35-45 pts. wt.), humic acid (4-6 pts. wt.), watermelon vine seedlings (6-8 pts. wt.), superphosphate (4-6 pts. wt.), monoammonium phosphate (4-6 pts. wt.), carbamide (6-10 pts. wt.), bone meal (12-16 pts. wt.), diammonium phosphate (4-5 pts. wt.), zinc sulfate (3-4 pts. wt.), borax (3-4 pts. wt.), magnesium sulfate (2-3 pts. wt.), crop stalk (25-35 pts. wt.), silkworm excrement (20-30 pts. wt.), eggshell powder (5-7 pts. wt.), soil additive (18-24 pts. wt.), and balanced amount of water. Soil additive comprises elm leaves( 35-45 pts. wt.), turtle shell powder (10-18 pts. wt.), amino acid chelated calcium (4-6 a2), amino acid chelated iron (4-6 pts. wt.), amino acid chelated zinc (4-6 pts. wt.), amino acid chelated copper (4-6 pts. wt.), amino acid chelated magnesium (4-6 pts. wt.), carnallite (2-3 pts. wt.), brassinosteroid lipid formulations (3-4 pts. wt.), beech bark fiber (5-7 pts. wt.), potassium epsom salts (3-4 pts. wt.), potassium phosphate dibasic (2-4 pts. wt.), nanocarbon (3-4 pts. wt.), potassium chloride (2-3 pts. wt.), and ash (20-30 pts. wt.). Soil additive is prepared by grinding elm leaves (60-80%) to obtain a powder. Amino acid chelated calcium, amino acid chelated iron, amino acid chelated zinc, amino acid chelated copper, amino acid chelated magnesium and water are mixed at 40-60 degrees C to obtain a paste. Obtained paste is dried by fluidized bed dryer to obtain fine particles. Obtained fine particles are mixed with remaining elm leaves, turtle shell powder, brassinosteroid lipid formulations, beech bark fiber, ash, nano carbon and water to obtain slurry. Obtained slurry is dried and granulated by using a disk pelletizer to obtain granules. Obtained powder and granules are mixed, and atomized for 5-10 minutes, then carnallite, potassium epsom salt, potassium phosphate, potassium chloride are added to atomized product to obtain a mixture. Obtained mixture is pulverized to obtain a powder of particle size 80-100 mesh. Obtained product is coated, and dried to obtain final product. An INDEPENDENT CLAIM is included for a method for preparing sustained release organic fertilizer, which involves:    (A) mixing silkworm excrement, pig manure, and water to obtain a mixture;    (B) watermelon vine seedlings, eggshell powder, and bone meal are mixed are mixed with water to obtain another mixture;    (C) fermenting obtained mixture for 15-20 days to obtain fermented product;    (D) grinding superphosphate, monoammonium phosphate, diammonium phosphate to obtain powder, and adding carbamide, zinc sulfate, borax, magnesium sulfate and water to it to obtain slurry, which is used for coating the particles;    (E) adding humic acid, and crop straw to fermented material to obtain third mixture, and keeping it for 10-15 days;    (F) mixing the obtained product with another mixture to obtain fourth mixture, and granulating it to obtain granules; and    (G) drying the obtained granules and coating it with obtained slurry to obtain final product.
