NOVELTY - Organic fertilizer comprises modified cinder (30-45 pts. wt.), sheep manure (10-20 pts. wt.), walnut powder (4-8 pts. wt.), leaves and branches of peach tree (2-6 pts. wt.), garlic waste (3-5 pts. wt.), rape straw powder (10-12 pts. wt.), chicken bone powder (2-3 pts. wt.), fulvic acid (3-4 pts. wt.), Rheum officinale powder (1-2 pts. wt.), Heracleum hemsleyanum residue powder (1-2 pts. wt.), biogas residue (12-15 pts. wt.), castor (5-10 pts. wt.), canal mud (5-8 pts. wt.), chitosan (1.5-1.8 pts. wt.), and polyethylene glycol (1-1.2 pts. wt.).    USE - Organic fertilizer used for walnuts (claimed).    ADVANTAGE - The organic fertilizer provides nutrients, and ensures growth and development of walnuts. The organic fertilizer improves soil structure and chemical properties of soil, and increases yield.    DETAILED DESCRIPTION - Organic fertilizer comprises modified cinder (30-45 pts. wt.), sheep manure (10-20 pts. wt.), walnut powder (4-8 pts. wt.), leaves and branches of peach tree (2-6 pts. wt.), garlic waste (3-5 pts. wt.), rape straw powder (10-12 pts. wt.), chicken bone powder (2-3 pts. wt.), fulvic acid (3-4 pts. wt.), Rheum officinale powder (1-2 pts. wt.), Heracleum hemsleyanum residue powder (1-2 pts. wt.), biogas residue (12-15 pts. wt.), castor (5-10 pts. wt.), canal mud (5-8 pts. wt.), chitosan (1.5-1.8 pts. wt.), polyethylene glycol (1-1.2 pts. wt.), Effective Microorganisms (RTM: Common species of anaerobic organisms found in all environments) microbial inoculum (2-3 pts. wt.), urea (1.4-2.2 pts. wt.), potassium dihydrogen phosphate (1.2-1.6 pts. wt.), ammonium molybdate (0.01-0.02 pts. wt.), zinc sulfate (0.2-0.5 pts. wt.), and borax (0.01-0.02 pts. wt.). An INDEPENDENT CLAIM is included for a method for preparing organic fertilizer, which involves:    (A) pulverizing modified cinder by 20-40 mesh sieve;    (B) soaking pulverized product in 2 mole/L sulfuric acid solution for 24-48 hours;    (C) discarding supernatant;    (D) cleaning residue with water to obtain pH of 6-7;    (E) drying cleaned residue;    (F) pulverizing residue by 200-500 mesh sieve to obtain fine powder;    (G) mixing chitosan, polyethylene glycol and deionized water in ratio of 3:2:80;    (H) mixing obtained product and fine powder in ratio of 1.5-2:1;    (I) drying obtained mixture;    (J) pulverizing obtained mixture by 100-200 mesh sieve;    (K) fermenting sheep manure, walnut core powder, chicken bone powder, radix angelicae pubescentis residue powder and canal mud with microbial inoculum at 45-65 degrees C for 15-20 days, where microbial inoculum comprises Bacillus licheniformis and Bacillus subtilis in ratio of 2-3:1;    (L) fermenting leaves and branches of peach tree, garlic waste, rape straw powder, biogas residue and castor with Effective Microorganisms in stack of height 1m for 2-3 days to obtain aerobic fermented material;    (M) mixing fermented products, cinder fine powder, and remaining raw materials;    (N) drying obtained mixture; and    (O) granulating dried product.
