NOVELTY - Fertilizer synergist comprises kaolin (34-40 pts. wt.), fulvic acid (7-10 pts. wt.), soybean meal (11-13 pts. wt.), cinder (9-11 pts. wt.), modified rock phosphate (60-80 pts. wt.), palygorskite powder (5-6 pts. wt.), cobalt chloride (2-3 pts. wt.), attapulgite clay (3-4 pts. wt.), and water. Modified phosphate rock comprises rock phosphate powder (90-110 pts. wt.), gamma-polyglutamate powder (1-2 pts. wt.), ferrous sulfate (4-8 pts. wt.), calcium bicarbonate (6-9 pts. wt.), Bacillus subtilis (2-3 pts. wt.), silicate bacteria (3-4 pts. wt.), and EDTA-chelated copper (18-22 pts. wt.).    USE - Fertilizer synergist used for increasing uptake of nitrogen and phosphorus in peanuts (claimed).    ADVANTAGE - The fertilizer synergist promotes growth and development of peanuts, facilitates subsequent planting of crops, and increases output of fruit and content of phosphorus potassium in soil.    DETAILED DESCRIPTION - Fertilizer synergist comprises kaolin (34-40 pts. wt.), fulvic acid (7-10 pts. wt.), soybean meal (11-13 pts. wt.), cinder (9-11 pts. wt.), modified rock phosphate (60-80 pts. wt.), palygorskite powder (5-6 pts. wt.), cobalt chloride (2-3 pts. wt.), attapulgite clay (3-4 pts. wt.), and water. Modified phosphate rock comprises rock phosphate powder (90-110 pts. wt.), gamma-polyglutamate powder (1-2 pts. wt.), ferrous sulfate (4-8 pts. wt.), calcium bicarbonate (6-9 pts. wt.), Bacillus subtilis (2-3 pts. wt.), silicate bacteria (3-4 pts. wt.), EDTA-chelated copper (18-22 pts. wt.), manganese humate (24-26 pts. wt.), black liquor (13-17 pts. wt.), and corn starch (35-45 pts. wt.). Modified rock phosphate is prepared by heating black liquor to facilitate its concentration, and then adding phosphate rock. Obtained mixture is calcined at 400-500 degrees C, and then mixed with gamma-polyglutamate powder, EDTA-chelated copper, manganese humate, and corn starch. Obtained mixture is sieved by 150 mesh sieve, and then mixed with water and ferrous sulfate at 40-60 degrees C. Calcium bicarbonate is added to obtained mixture, and then heated at 60-70 degrees C under stirring condition for 30 minutes. Obtained mixture is cooled. Bacillus subtilis and silicate bacteria are dded to cooled product, and kept at 20-30 degrees C for 7-8 days. Obtained mixture is air-dried and pulverized by 100-120 mesh sieve to obtain fine powder. An INDEPENDENT CLAIM is included for a method for preparing fertilizer synergist, which involves:    (A) calcining kaolin at 750-850 degrees C for 2-4 hours;    (B) pulverizing calcined kaolin by 100 mesh sieve;    (C) fermenting fulvic acid, soybean powder, cinder and water in fermentation tank at 35-45 degrees C for 2-3 weeks;    (D) pulverizing fermented product to obtain fine powder;    (E) mixing fine powder, attapulgite clay and kaolin powder;    (F) adding remaining ingredients to obtained mixture; and    (G) pulverizing obtained mixture by 80-100 mesh sieve to obtain the final product.
