Effective microorganism technology is a method in which mixed culture of beneficial microorganisms is applied to soil as an inoculant, which increases microbial diversity; enhance soil quality as well as growth, yield and quality of crops. The necessity for chemical fertilisers and pesticides is lowered since EM cultures expedite the decomposition of organic wastes, increase the availability of mineral nutrients and desirable organic compounds to plants, and augment the activity of beneficial microorganisms. Due to its eco-friendly nature and minimal demand on resources like inputs and money, EM has a pretty broad range of applications in many facets of human society. Therefore, effective microorganism technology can be considered as an effective method in organic fertilization.
