NOVELTY - Method for preparing fermented fertilizer is claimed. The fermented fertilizer comprises urea, potassium sulfate, diammonium phosphate, residue of traditional Chinese medicinal herbs, corncob, clay, Bacillus subtilis, borax, zinc sulfate, magnesium sulfate, magnesium sulfite, magnesium hydroxide, calcium hydroxide, Stellera chamaejasme, radix aconiti feri and soil conditioner.    USE - The method is useful for preparing fermented fertilizer (claimed) which is used for adsorbing heavy metals in soil.    ADVANTAGE - The prepared fermented fertilizer contains a large number of trace elements which are beneficial to humans, and increases crop yield.    DETAILED DESCRIPTION - Method for preparing fermented fertilizer is claimed. The fermented fertilizer comprises 50-60 pts. wt. urea, 50-60 pts. wt. potassium sulfate, 40-55 pts. wt. diammonium phosphate, 100-150 pts. wt. residue of traditional Chinese medicinal herbs, 200-250 pts. wt. corncob, 100-145 pts. wt. clay, 2-3 pts. wt. Bacillus subtilis, 10-15 pts. wt. borax, 10-15 pts. wt. zinc sulfate, 20-30 pts. wt. magnesium sulfate, 10-15 pts. wt. magnesium sulfite, 15-20 pts. wt. magnesium hydroxide, 30-50 pts. wt. calcium hydroxide, 30-45 pts. wt. Stellera chamaejasme, 45-60 pts. wt. radix aconiti feri and 8-10 pts. wt. soil conditioner. The soil conditioner comprises 120-130 pts. wt. weathered coal, 2-3 pts. wt. alcohol ester, 3-4 pts. wt. nano jade powder, 1-2 pts. wt. borax, 1-2 pts. wt. salicylic acid, 2-3 pts. wt. nano calcium carbonate powder, 2-3 pts. wt. neopentyl glycol, 1-2 pts. wt. soybean oil, 2-3 pts. wt. sodium selenite, 3-4 pts. wt. Eucalyptus oil, 4-5 pts. wt. Mallotus apelta root, 3-4 pts. wt. banana root and suitable amount of water. The soil conditioner is prepared by crushing the M.apelta root, and banana root into powder, grinding with weathered coal, borax and salicylic acid into paste, adding water to the paste, heating the mixture at 80-90 degrees C, grinding with nano jade powder, nano calcium carbonate powder and neopentyl glycol for 30-40 minutes, adding the remaining ingredients, concentrating the mixture, granulating the mixture and drying the granules.
