NOVELTY - Organic fertilizer comprises 20-24 pts. wt. rice straw, 15-18 pts. wt. wheat straw, 10-14 pts. wt. corrosion leaves, 8-10 pts. wt. loess, 5-7 pts. wt. plant ash, 0.05-0.1 pts. wt. biological microbial inoculum, 0.3-0.5 pts. wt. magnesium sulfate, 0.4-0.7 pts. wt. zinc sulfate, 0.1-0.3 pts. wt. sodium sulfate, 0.05-0.08 pts. wt. fulvic acid, 2-5 pts. wt. urea, 0.01-0.02 pts. wt. acetic acid, 0.02-0.05 pts. wt. sodium bisulfite, 0.2- 0.4 pts. wt. auxiliary agent, and remaining amount of water.    USE - The organic fertilizer is useful for fermentation of crop straw (claimed), and for promoting growth of plants.    ADVANTAGE - The organic fertilizer can be prepared with reduced energy consumption and with less amount of chemicals in an eco friendly manner.    DETAILED DESCRIPTION - Organic fertilizer comprises 20-24 pts. wt. rice straw, 15-18 pts. wt. wheat straw, 10-14 pts. wt. corrosion leaves, 8-10 pts. wt. loess, 5-7 pts. wt. plant ash, 0.05-0.1 pts. wt. biological microbial inoculum, 0.3-0.5 pts. wt. magnesium sulfate, 0.4-0.7 pts. wt. zinc sulfate, 0.1-0.3 pts. wt. sodium sulfate, 0.05-0.08 pts. wt. fulvic acid, 2-5 pts. wt. urea, 0.01-0.02 pts. wt. acetic acid, 0.02-0.05 pts. wt. sodium bisulfite, 0.2- 0.4 pts. wt. auxiliary agent, and remaining amount of water. The inoculum is prepared by decomposition of Bacillus megaterium. The auxiliary agent comprises 2 pts. wt. dimethyl propane ester, 0.2-0.5 pts. wt. sodium carboxymethyl cellulose, 0.3-0.8 pts. wt. epichlorohydrin, 2-3 pts. wt. dimethicone, 10-12 pts. wt. nanocarbon, 0.8-1.2 pts. wt. diethylamino ethanol, 13-16 pts. wt. coal ash, 1.5-2 pts. wt. ammonium chloride, and remaining amount of water. The auxiliary agent is prepared by dissolving diethylamino ethanol in water, adding dimethyl propane ester, sodium carboxymethyl cellulose, epichlorohydrin, dimethicone and ammonium chloride, heating the mixture to 60-80 degrees C, stirring the mixture for 10-15 minutes, adding nano-carbon and the coal ash, drying, and crushing the obtained product. AN INDEPENDENT CLAIM is also included for preparing ammonium chloride comprising mixing rice straw and wheat straw with water, grinding the mixture to 200 meshes, adding enough water for 5-10 minutes to make the material soften, filtering the redundant water, mixing corrosion leaves, loess and plant ash, adding biological microbial inoculum and water, uniformly stirring the mixture, rolling, fermenting the mixture for 4 days, adding magnesium sulfate, zinc sulfate, sodium sulfate, fulvic acid, urea, edible acetic acid, sodium bisulfite, auxiliary agent and other components, adding water, ultrasonically dispersing the mixture at a sound wave intensity of 0.4- 0.8 w/cm2, drying the mixture, granulating, and then packaging.
