DETAILED DESCRIPTION - Fertilizer comprises 35-45 pts. wt. starch, 25-35 pts. wt. urea, 10-16 pts. wt. soil modifying agent, 8-12 pts. wt. egg white, 6-8 pts. wt. calcium powder, 6-8 pts. wt. chitosan, 5-7 pts. wt. shell powder, 5-6 pts. wt. potassium dihydrogen phosphate, 4-6 pts. wt. carboxymethyl cellulose, 4-5 pts. wt. zinc sulfate, 5-6 pts. wt. boric acid, 4-5 pts. wt. cobalt chloride, 3-5 pts. wt. nickel sulfate, 4-5 pts. wt. fly ash, 4-5 pts. wt. effective microorganism, and remained water. The soil modifying agent comprises 18-24 pts. wt. albic soil, 14-18 pts. wt. Kanuma soil, 10-15 pts. wt. birch sawdust, 9-16 pts. wt. maple leaves, 6-8 pts. wt. Crotalaria leaves, 6-7 pts. wt. fulvic acid, 5-8 pts. wt. nano carbon powder, 4-7 pts. wt. white radish peel, 5-6 pts. wt. zinc gluconate, 4-6 pts. wt. water hyacinth, 4-6 pts. wt. Ampelopsis root, 3-5 pts. wt. calcium hydrogen phosphate and 4-5 pts. wt. calcium cyanamide. The modifying agent is prepared by mixing Kanuma soil and albic soil, mixing, calcinating mixture for 40-60 minutes to obtain fine powder, mixing water hyacinth, Ampelopsis root, and Crotalaria leaves, extracting, collecting residue, drying residue, grinding dried residue to obtain fine powder, adding calcium hydrogen phosphate, zinc gluconate and calcium cyanamide, mixing uniformly to obtain paste, and adding remaining raw materials except nano carbon powder, mixing uniformly, leaving mixture for 15-20 days, stirring uniformly for every 2-4 days, adding nano carbon powder, stirring uniformly and granulating mixture to obtain the product. An INDEPENDENT CLAIM is included for method for preparing fertilizer, which involves (a) mixing starch, egg white and shell powder, crushing, placing in a water bath at 60-80 degrees C for 40-60 minutes, and stirring uniformly to obtain paste, (b) mixing obtained paste with chitosan, carboxymethyl cellulose, fly ash and effective microorganism, performing aerobic fermentation for 20-30 days, turning mixture once in every 3-5 days, and drying fermented material, (c) mixing boric acid, cobalt chloride, nickel sulfate, potassium dihydrogen phosphate, calcium powder, and zinc sulfate, heating at low temperature for 10-30 minutes, stirring uniformly at 1000-1400 revolutions per minute for 30-50 minutes, and granulating mixture, and (d) mixing processed material obtained in steps (a)-(b), and remaining raw materials to obtain the product.
