EM is the abbreviation of Effective Microorganisms, originated by Dr. Teruo Higa. It is a mixed microbial culture of selected species of microorganisms such as lactic acid bacteria, yeasts, photosynthetic bacteria and actinomycetes. All of these are mutually compatible with one another and coexist in liquid culture. When applied to soil as an inoculant, these microorganisms function cooperatively to exert beneficial effects on soil quality. Some of the microorganisms in EM are known to produce bioactive substances such as vitamins, hormones, enzymes, antioxidants and antibiotics that can directly, or indirectly enhance plant growth and protection. It has also many uses for environmental applications.
