DETAILED DESCRIPTION - Fertilizer comprises 23-27 pts. wt. malt powder, 3-5 pts. wt. potassium, 4-6 pts. wt. weathered coal, 2-3 pts. wt. Lactobacillus acidophilus, 1-2 pts. wt. sodium nitrophenolate, 3-4 pts. wt. ferrous sulfate, 28-32 pts. wt. cassava residue, 6-8 pts. wt bentonite, 5-7 pts. wt. furfural residue, 34-36 pts. wt. corn cob, 70-90 pts. wt. herba patriniae, 5-7 pts. wt. silicate, 4-7 pts. wt. silicon hydroxyapatite and 5-7 pts. wt. auxiliary agent, where the auxiliary agent comprises 4-6 pts. wt. iron ore powder, 3-6 pts. wt. ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid) (EDDHA) chelated iron, 8-10 pts. wt. fresh konjac, 3-4 pts. wt. magnesium amino acid chelate, 3-4 pts. wt. copper amino acid chelate, 3-4 pts. wt. manganese amino acid chelate, 1-3 pts. wt. methyl methacrylate, 0.1-0.2 pts. wt. N-butyl thiophosphoric triamide, 12-16 pts. wt. fresh grass and 8-12 pts. wt. coral rock ash. The auxiliary agent is prepared by cleaning the fresh grass and konjac using water, crushing the materials and extracting the mixture, filtering the liquid, adding the remaining raw materials, stirring uniformly, wet granulating the mixture, coating the granules and drying the coated granules. An INDEPENDENT CLAIM is included for method of preparing the fertilizer, which involves adding proper amount of water to the fermentation material, inoculating the effective microorganisms, performing anaerobic fermentation for 8-12 days, adding the other raw materials, performing aerobic fermentation for 60-72 hours, drying the fermented material, adding auxiliary agent, stirring uniformly, formulating the mixture into particles of 8-12 mm and drying the particles under low temperature.
