NOVELTY - Fertilizer comprises (in pts.wt.): soybean straw (40-50), charcoal (20-25), peanut (20-25), urea (10-14), lignite (11-13), basalt powder (12-14), medical stone (11-14), peat (9-13), humus (10-12), Amorpha fruticosa (5-7), liao spicy herb (4-5), calcium superphosphate (10-12), potassium sulfate (11-13) and soil modifier (9-11). The soil modifier comprises (in pts.wt.): bamboo charcoal powder (100-120), lime (1-2), shell powder (3-4), flour (1-2), carbon powder (1-2), sand (2-3), manganese sulfate (1-2), ferrous sulfate (3-4), jade powder (2-3) and ascorbic acid (1-2).    USE - Fertilizer used for increasing yield and improving quality of plant.    ADVANTAGE - The fertilizer improves soil fertility in eco-friendly manner.    DETAILED DESCRIPTION - Fertilizer comprises (in pts.wt.): soybean straw (40-50), charcoal (20-25), peanut (20-25), urea (10-14), lignite (11-13), basalt powder (12-14), medical stone (11-14), peat (9-13), humus (10-12), Amorpha fruticosa (5-7), liao spicy herb (4-5), calcium superphosphate (10-12), potassium sulfate (11-13) and soil modifier (9-11). The soil modifier comprises (in pts.wt.): bamboo charcoal powder (100-120), lime (1-2), shell powder (3-4), flour (1-2), carbon powder (1-2), sand (2-3), manganese sulfate (1-2), ferrous sulfate (3-4), jade powder (2-3), ascorbic acid (1-2), Paulownia tree powder (4-5), paraffin (2-3) and Angelica (2-3). The soil modifier is prepared by mixing bamboo charcoal powder, manganese sulfate, borax, ferrous sulfate and jade powder and grinding to obtain 200-400-mesh powder. Carbon powder, lime and other components are added to obtained powder. The obtained mixture is ground and stirred at 1200-1500 revolution per minute to obtain soil modifier. An INDEPENDENT CLAIM is included for a method for preparing fertilizer, which involves:    (A) crushing soybean straw and peanut into powder of 120 meshes;    (B) grinding medical stone into 180 meshes of powder;    (C) adding lignite, basalt powder, peat, humus and soil modifier;    (D) keeping the mixture for 3 months to compost;    (E) soak Amorpha fruticosa and grass in proper amount of water for 24 hours;    (F) grinding bamboo charcoal with obtained mixture;    (G) adding urea, calcium superphosphate and other component; and    (H) stirring, drying and granulating the obtained mixture to obtain product.
