NOVELTY - Multifunctional microbial organic fertilizer comprises multi-effect biological fertilizer (70-90%) and agricultural organic fertilizer (10-30%). Agricultural organic fertilizer is prepared by fermenting organic waste and agricultural raw materials in presence of leavening agent comprising facultative anaerobic bacteria. Agricultural organic waste raw material is selected from corn straw, soybean straw, rice straw, weeds, animal excreta, or their combinations. Leavening agent is prepared by culturing single colony Actinomycetes, yeast and Streptomyces in ratio of 3:3:4.    USE - Multifunctional microbial organic fertilizer.    ADVANTAGE - The multifunctional microbial organic fertilizer is odorless and rich in nutrients, and prevents plant diseases, insects and pests.    DETAILED DESCRIPTION - Multifunctional microbial organic fertilizer comprises multi-effect biological fertilizer (70-90%) and agricultural organic fertilizer (10-30%). Agricultural organic fertilizer is prepared by fermenting organic waste and agricultural raw materials in presence of leavening agent comprising facultative anaerobic bacteria. Agricultural organic waste raw material is selected from corn straw, soybean straw, rice straw, weeds, animal excreta, or their combinations. Leavening agent is prepared by culturing single colony Actinomycetes, yeast and Streptomyces in ratio of 3:3:4 at 25 degrees C for 1-3 days in lysogeny broth medium. Yeast extract is inoculataed in culture medium at 25-28 degrees C at 180-220 revolutions/minute, and then cultured for 2-6 days. Obtained culture product is added to sterile liquid medium in ratio of 1:150-200, and cultured at 40-50 degrees C at 180 revolutions/minute for 24 hours. Dry rice straw is added to obtained product, and then sterilized at 121 degrees C for 20 minutes. Obtained product is siluted with water in ratio of 1:400-800, and then cultured at 50 degrees C for 7-10 days to obtain leavening agent. An INDEPENDENT CLAIM is included for a method for preparing multifunctional microbial organic fertilizer, which involves:    (A) preparing leavening agent;    (B) preparing agricultural organic waste material product;    (C) fermenting both the obtained products to obtain compost;    (D) fermenting obtained compost in piles of height 1.5m in presence of leavening agent;    (E) adding water to obtained product to obtain product having moisture content of 55-65%;    (F) discontinuing fermentation after 50-90 days; and    (G) mixing obtained product with multi-effect biological fertilizer to obtain the final product.
