NOVELTY - A soil desertification controlling nutritional formulation comprises decomposed domestic garbage, bacterial liquid C, potassium, urea, phosphorus pentoxide, potassium sulfate, amino acid, ammonium molybdate or sodium molybdate, manganese sulfate, ferrous sulfate, zinc sulfate, magnesium sulfate, boron sand, fulvic acid, EDTA, azone and caustic soda. The decomposed domestic garbage having moisture content of 35-45% is prepared by uniformly stirring straw and/or sawdust, urea, bacterial liquid A and bacterial liquid B, fermenting at 45-60 degrees C for 48-55 hours and sterilizing.    USE - Soil desertification controlling nutritional formulation.    ADVANTAGE - The formulation has rich nutrition, low cost, no toxicity, pollution and residue, and prevents bacterial diseases.    DETAILED DESCRIPTION - A soil desertification controlling nutritional formulation comprises 79.5-90.7 pts. wt. decomposed domestic garbage, 0.3-0.5 pt. wt. bacterial liquid C, 1-3 pts. wt. potassium, 1-1.5 pts. wt. urea, 1-2 pts. wt. phosphorus pentoxide, 0.5-1 pt. wt. potassium sulfate, 1-1.5 pts. wt. amino acid, 0.2-0.5 pt. wt. ammonium molybdate or sodium molybdate, 0.3-1 pt. wt. manganese sulfate, 1-2 pts. wt. ferrous sulfate, 0.3-1 pt. wt. zinc sulfate, 1-2 pts. wt. magnesium sulfate, 0.5-1 pt. wt. boron sand, 0.5-1.5 pts. wt. fulvic acid, 0.2-1 pt. wt. EDTA, 0.3-0.5 pt. wt. azone and 0.2-0.5 pt. wt. caustic soda. The decomposed domestic garbage having moisture content of 35-45% is prepared by uniformly stirring straw and/or sawdust, urea, bacterial liquid A and bacterial liquid B, fermenting at 45-60 degrees C for 48-55 hours and sterilizing. An INDEPENDENT CLAIM is included for preparation of soil desertification controlling nutritional formulation comprising mixing Bacillus thuringiensis, Lactobacillus subsp. bulgaricus and Lactobacillus casei at ratio of 1:1:1 to obtain bacterial liquid A; mixing Leucobacter, Thiobacillus thioparus, Aspergillus awamori, Sporotrichum, Bacillus megaterium, Bacillus subtilis, Trichoderma koningii and Phanerochetee at ratio of 1:1:1:1:1:1:1:1 to obtain bacterial liquid B; mixing Streptomyces, Bacillus megaterium and Bacillus mucilaginosus at ratio of 1:1:1 to obtain bacterial liquid C; mixing raw materials except caustic soda; and regulating pH with caustic soda.
