About EM

EM is a sustainable microbial inoculant that achieves synergistic effects by combining beneficial microorganisms which exist in nature. EM activates local and native microorganisms that live in soil and water to boost performance. One of the strengths of EM is that it is a diverse combination of microbes, and this gives it versatility in terms of a wide scope of applications that it can be used on. EM was initially developed to improve soils and enhance crops but has evolved to benefit a wide range of areas and is used in numerous fields including agriculture, animal husbandry and environmental purification in more than 100 countries around the world.
