NOVELTY - Preparing fertilizer involves utilizing 65-85 pts. wt. urea, 45-65 pts. wt. monoammonium phosphate, 30-50 pts. wt. potassium sulfate, 300-350 pts. wt. rice straw, 300-600 pts. wt. animal feces and 9-12 pts. wt. soil activating agent. The soil activating agent is made of 120-125 pts. wt. zeolite powder, 4-6 pts. wt. nano jade powder, 2-3 pts. wt. sodium dodecylbenzenesulfonate, 3-4 pts. wt. magnesium stearate, 4-5 pts. wt. talcum powder, 3-4 pts. wt. white granulated sugar, 2-3 pts. wt. sodium lignin sulfonate and 6-7 pts. wt. morpholine.    USE - Method for preparing fertilizer (claimed).    ADVANTAGE - The method enables to prepare fertilizer that reduces absorption of heavy metal element and increases absorption of trace element by crops, and increase crop yield.    DETAILED DESCRIPTION - Preparing fertilizer involves utilizing 65-85 pts. wt. urea, 45-65 pts. wt. monoammonium phosphate, 30-50 pts. wt. potassium sulfate, 300-350 pts. wt. rice straw, 300-600 pts. wt. animal feces and 9-12 pts. wt. soil activating agent. The soil activating agent is made of 120-125 pts. wt. zeolite powder, 4-6 pts. wt. nano jade powder, 2-3 pts. wt. sodium dodecylbenzenesulfonate, 3-4 pts. wt. magnesium stearate, 4-5 pts. wt. talcum powder, 3-4 pts. wt. white granulated sugar, 2-3 pts. wt. sodium lignin sulfonate, 6-7 pts. wt. morpholine, 2-3 pts. wt. maifanite stone, 10-12 pts. wt. borax, 3-4 pts. wt. zinc sulfate, 4-5 pts. wt. ferrous sulfate, 5-6 pts. wt. sodium metasilicate and 3-4 pts. wt. water. The soil activating agent is prepared by mixing ground zeolite powder, maifanite stone, borax and talcum powder in balanced amount of water to obtain slurry. The slurry is heated to 70-80 degrees C, and rest components are ground to obtain powder, where the powder is mixed with the slurry and stirred uniform to obtain a mixture. The mixture is dried for 40-60 minutes, and then granulated to obtain the soil activating agent. An INDEPENDENT CLAIM is included for a method for preparing fertilizer, which involves:    (A) mixing and stirring uniformly straw and animal feces to carry out fermentation process for 7-8 days in a covered fermentation pool, and then exposing in sunshine to obtain a fermentation product;    (B) drying and crushing the fermentation product, mixing uniformly urea, monoammonium phosphate and potassium sulfate to obtain a mixture, and then crushing and granulating to obtain granules; and    (C) adding the granules in the soil activating agent, and then mixing uniformly to obtain a final product.
