NOVELTY - Fertilizer comprises 35-55 pts. wt. earthworm, 6-7 pts. wt. ammonium polyphosphate, 8-12 pts. wt. wood vinegar, 4-5 pts. wt. sodium sulfate, 40-60 pts. wt. soybean curd residue, 10-12 pts. wt. medical stone, 4-6 pts. wt. ammonium sulfate, 100-110 pts. wt. fresh Enteromorpha, 5-7 pts. wt. composite microbial inoculum, 240-260 pts. wt. wheat straw, 23-27 pts. wt. fresh urine and balanced amount of water. The microbial inoculum comprises Rhizopus oryzae, Bacillus subtilis and Bacillus cereus in weight ratio of 1:2:2.    USE - Fertilizer.    ADVANTAGE - The fertilizer prevents nutrient loss, and ensures increased nutrient release rate, soil fertility, fertilizer utilization efficiency, good nutrient absorption and slow release effect.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing fertilizer, which involves:    (A) crushing Enteromorpha, soybean curd residue, earthworm and medical stone mixture;    (B) mixing crushed material with water and microbial inoculum uniformly;    (C) fermenting obtained mixture at 70 degrees C for 18-23 days;    (D) filtering fermented material to obtain fermentation liquid and residue;    (E) crushing wheat straw;    (F) heating crushed straw in kiln apparatus at 450-550 degrees C for 2-3 hours;    (G) heating obtained material at 750-850 degrees C for 1-2 hours to obtain wheat straw coal powder that is cooled to room temperature;    (H) heating fermentation liquid, vinegar and sodium sulfate at 55-65 degrees C for 50-70 minutes;    (I) mixing obtained mixture with ammonium sulfate and ammonium polyphosphate evenly;    (J) cooling obtained mixture to room temperature to obtain nutrient liquid;    (K) stirring fresh urine and nutrient liquid uniformly;    (L) adjusting pH of obtained solution to 3.8-4.2 using citric acid solution;    (M) concentrating obtained liquid mixture;    (N) mixing concentrated mixture with wheat straw coal powder;    (O) drying obtained mixture;    (P) mixing dry mixture with fermentation residue and remaining material; and    (Q) pelletizing obtained mixture to obtain granule as product that is weighed, packaged and stored.
