NOVELTY - Fertilizer comprises cottonseed hull, Chinese herbal medicinal residue, gelatin, clay, rice straw, sesame straw, sea shell powder, effective microbial (EM) inoculant, ammonium hydrogen carbonate, potassium chloride, ammonium dihydrogen phosphate, microelement, cross-linking agent and water. The cross-linking agent comprises acrylamide, ethylene glycol dimethacrylate, glycerol, limestone, ethanol, sodium dodecyl sulfate, industrial castor oil and water.    USE - As fertilizer.    ADVANTAGE - The fertilizer exhibits moisture-proof property, has good stability and improved permeability, and is prepared easily.    DETAILED DESCRIPTION - Fertilizer comprises 15-20 pts. wt. cottonseed hull, 30-45 pts. wt. Chinese herbal medicinal residue, 3-5 pts. wt. gelatin, 5-10 pts. wt. clay, 15-20 pts. wt. rice straw, 20-25 pts. wt. sesame straw, 1-3 pts. wt. sea shell powder, 2-3 pts. wt. effective microbial (EM) inoculant, 20-25 pts. wt. ammonium hydrogen carbonate, 14-18 pts. wt. potassium chloride, 10-14 pts. wt. ammonium dihydrogen phosphate, 5-10 pts. wt. microelement, 4-5 pts. wt. cross-linking agent and suitable amount of water. The cross-linking agent comprises 8-10 pts. wt. acrylamide, 2-3 pts. wt. ethylene glycol dimethacrylate, 2-4 pts. wt. glycerol, 10-15 pts. wt. limestone, 5-8 pts. wt. ethanol, 2-4 pts. wt. sodium dodecyl sulfate, 12-16 pts. wt. industrial castor oil and suitable amount of water. The cross-linking agent is prepared by (i) mixing the ethanol, with 5-8 times water, stirring obtained solution, and adding ethylene glycol dimethacrylate to the solution, (ii) crushing the limestone to obtain powder, sieving the powder using sieve having 200-250 mesh size, mixing the powder with glycerol, water, sodium dodecyl sulfate and industrial castor oil, and uniformly stirring obtained mixture for 20-30 minutes to obtain emulsion, and (iii) mixing product obtained in step (i) with acrylamide and emulsion obtained in step (ii), stirring obtained mixture at 70-90 degrees C for 30-40 minutes to obtain product. An INDEPENDENT CLAIM is included for method for preparing the fertilizer, which involves (a) mixing the sesame straw and rice straw, immersing mixture in 4-7 times water for 8-10 hours, milling obtained mixture for 30-40 minutes to obtain slurry, centrifuging the slurry and removing supernatant, and drying precipitate to obtain powder, (b) adding the powder obtained in step (a) to carbonization furnace, performing carbonization at 600-700 degrees C for 5-8 hours under sealed conditions, and cooling carbonized product to room temperature, (c) mixing the cottonseed hull, Chinese herbal medicinal residue with EM inoculant, adding water to the mixture, controlling water content of the mixture at 50%, fermenting the mixture at 35-40 degrees C for 15-20 days, adding gelatin powder, product obtained in step (b) and ammonium hydrogen carbonate powder, potassium chloride powder, ammonium dihydrogen phosphate powder and microelement powder, uniformly mixing and stirring the mixture for 15-25 minutes, adding water to the mixture, controlling water content of the mixture at 30-40%, and pelletizing the mixture to obtain pellets having particle diameter of 3-4 mm, and (d) mixing the clay, sea shell powder, cross-linking agent and remaining components, adding 3-5 times water to mixture, stirring the mixture for 30-40 minutes, uniformly spraying product obtained in step (c) on the mixture, preheating obtained mixture at 80-90 degrees C, and drying obtained product.
