NOVELTY - Preparing microbial organic fertilizer involves obtaining bio-fermentation agent by fermenting mixture of 8-10 pts. wt. adsorbent, 3-5 pts. wt. calcium dihydrogen phosphate, 6-8 pts. wt. fermented soybean meal, 10-15 pts. wt. rice, 10-15 pts. wt. maize flour, 3-5 pts. wt. rapeseed cake, 10-15 pts. wt. wheat bran, 2-3 pts. wt. effective microbial agent, 1-2 pts. wt. yeast, 1-2 pts. wt. Bacillus subtilis, 1-2 pts. wt. Bacillus megaterium, 1-2 pts. wt. Lactobacillus with aqueous solution containing 2% moisture molasses at 25-30 degrees C anaerobically for 7-10 days.    USE - Method for preparing microbial organic fertilizer used for improving soil salinity (claimed).    ADVANTAGE - The method enables to prepare microbial organic fertilizer that adjusts soil microbial balance, accelerates plant growth, decomposes soil organic and inorganic substance, increases crop stress resistance and yield, and improves soil aggregate, permeability and fertility.    DETAILED DESCRIPTION - Preparing microbial organic fertilizer involves obtaining bio-fermentation agent by fermenting mixture of 8-10 pts. wt. adsorbent, 3-5 pts. wt. calcium dihydrogen phosphate, 6-8 pts. wt. fermented soybean meal, 10-15 pts. wt. rice, 10-15 pts. wt. maize flour, 3-5 pts. wt. rapeseed cake, 10-15 pts. wt. wheat bran, 2-3 pts. wt. effective microbial agent, 1-2 pts. wt. yeast, 1-2 pts. wt. Bacillus subtilis, 1-2 pts. wt. Bacillus megaterium, 1-2 pts. wt. Lactobacillus with aqueous solution containing 2% moisture molasses at 25-30 degrees C anaerobically for 7-10 days. The bio-fermentation agent (3-5 pts. wt.), seaweed (10-20 pts. wt.), crushed straw (20-30 pts. wt.), feces (45-55 pts. wt.) and non-starch polysaccharidase (1-2 pts. wt.) are mixed uniformly. The obtained mixture is fermented at 28-32 degrees C for 10-12 days. The obtained mixture is mixed with brown coal containing fulvic acid (20-30 pts. wt.), lees (5-10 pts. wt.), nitrifying bacteria (1-2 pts. wt.) and bio-fermentation agent (1-2 pts. wt.). The obtained mixture is fermented at 28-35 degrees C for 3-5 days. The fermented material is crushed using pulverizer. The crushed material is granulated and dried to obtain product.
