NOVELTY - Controlled-release fertilizer is prepared using tobacco leaf residue, camphor leaf, cattle manure, corncob, ammonium sulfate, zinc sulfate, calcium sulfate, sodium silicate, borax, sodium carboxymethyl cellulose, sodium lauroyl sarcosinate, lotus leaf residue, coffee ground, clove leaf oil, ferrous chloride, raw garlic powder, glucono- delta -lactone and additive.    USE - The controlled-release fertilizer is useful for peanut for providing resistance against diseases (claimed).    DETAILED DESCRIPTION - Controlled-release fertilizer is prepared using 1-3 pts. wt. tobacco leaf residue, 5-6 pts. wt. camphor leaf, 20-25 pts. wt. cattle manure, 12-15 pts. wt. corncob, 20-22 pts. wt. ammonium sulfate, 4-5 pts. wt. zinc sulfate, 8-10 pts. wt. calcium sulfate, 2-3 pts. wt. sodium silicate, 6-8 pts. wt. borax, 8-10 pts. wt. sodium carboxymethyl cellulose, 1-2 pts. wt. sodium lauroyl sarcosinate, 15-18 pts. wt. lotus leaf residue, 6-8 pts. wt. coffee ground, 0.2-0.3 pts. wt. clove leaf oil, 2-4 pts. wt. ferrous chloride, 1-3 pts. wt. raw garlic powder, 1-3 pts. wt. glucono- delta -lactone and 3-5 pts. wt. additive. The additive comprises 1-3 pts. wt. cinnamon oil, 1-2 pts. wt. sodium dodecylbenzenesulfonate, 2-3 pts. wt. manganese sulfate, 4-5 pts. wt. caseinophosphopeptide, 0.01-0.02 pts. wt. nano carbon, 6-8 pts. wt. sodium carboxymethyl starch, 2-3 pts. wt. sodium bicarbonate, and 1-2 pts. wt. alpha -lipoic acid and is prepared by mixing sodium dodecylbenzenesulfonate with 10 times its water to obtain mixture, heating the obtained mixture at 55-65 degrees C, stirring temperature heated mixture till the mixture dissolves completely, adding cinnamon oil, manganese sulfate, caseinophosphopeptide, and nano carbon to the stirred mixture and mixing the obtained mixture for 40-50 minutes, adding remaining raw materials to the mixed mixture and stirring resulting mixture for 1-2 hours and cooling the stirred mixture to normal temperature to obtain product. An INDEPENDENT CLAIM is included for method of preparing the controlled-release fertilizer, which involves (a) crushing lotus leaf residue and coffee grounds to obtain 80 mesh size powder, subjecting the obtained powder to carbonization treatment at 400-500 degrees C for 1-2 hours, soaking the resulting powder for 3-4 hours by adding 8-10% dilute hydrochloric acid solution, filtering the soaked powder and drying the filtrate, (b) crushing tobacco leaf residue, camphor leaves and corncob to obtain powder, diluting the obtained powder using water in weight ratio of 1:0.3, adding suitable amount of complex microbial agent to the resulting mixture, fermenting the obtained mixture at normal temperature for 25-30 days, filtering the fermentation product, mixing the resulting filtrate with the filtrate obtained in the step (a), zinc powder, sulfuric acid, borax, ferrous chloride, and additive to obtain mixture, and stirring the obtained mixture for 1-2 hours to obtain slurry, (c) heating sodium carboxymethyl cellulose, and sodium lauroyl sarcosinate at 50-60 degrees C by adding suitable amount of water, and adding clove leaf oil, and glucono- delta -lactone to the heated mixture and stirring resulting mixture for 40-50 minutes to obtain coating agent, and (d) mixing the slurry obtained in the step (b) with remaining raw materials to obtain mixture, granulating the resulting mixture at 50-60 degrees C to obtain granules, coating the granules with 5-8 wt.% coating agent obtained in the step (c) and drying product.
