NOVELTY - Preparing probiotic organic fertilizer involves performing anaerobic fermentation, aerobic fermentation and then producing organic fertilizer. The anaerobic fermentation is performed by mixing 320-350 pts. wt. soybean meal, 20-30 pts. wt. rice bran, 380-400 pts. wt. fish meal, 20-30 pts. wt. bacteria, 20-30 pts. wt. brown sugar, 1-2 pts. wt. yeast and 200-210 pts. wt. water and placing in closed container for anaerobic fermentation for 2-3 days to obtain product. The water content of soybean meal, rice bran and fish meal is 10-15%. and of brown sugar is 3-5%.    USE - Method for preparing organic fertilizer (claimed).    ADVANTAGE - The method enables to prepare high yield of probiotic organic fertilizer in simple and eco-friendly manner.    DETAILED DESCRIPTION - Preparing probiotic organic fertilizer involves performing anaerobic fermentation, aerobic fermentation and then producing organic fertilizer. The anaerobic fermentation is performed by mixing 320-350 pts. wt. soybean meal, 20-30 pts. wt. rice bran, 380-400 pts. wt. fish meal, 20-30 pts. wt. bacteria, 20-30 pts. wt. brown sugar, 1-2 pts. wt. yeast and 200-210 pts. wt. water and placing in closed container for anaerobic fermentation for 2-3 days to obtain product. The water content of soybean meal, rice bran and fish meal is 10-15%. and of brown sugar is 3-5%. The bacteria includes lactic acid bacteria, yeasts, anaerobic actinomycetes or photosynthetic bacteria. The aerobic fermentation is performed by heating wheat and corn at 80-90 degrees C for 5-10 minutes. The mixture is cooled and then aerobic fermentation is performed for 48 hours. The microorganisms includes fungus that degrades cellulose include high fever actinomycetes,and Basidiomycetes fungi, white rot fungi, decaying vegetation mold, phleomycin bacilli for decomposing lignin. The products of anaerobic and aerobic fermentation are mixed in ratio 3:1. The water content is adjusted to 30-35%. The mixture is transferred to fermentation equipment at 25-30 degrees C, stirring for every 4-5 hours, and then stirring for every 15-20 minutes with oxygen to obtain a moisture content of 12-16%. The product is packaged to obtain final product.
