  • Agricultural production is mainly depends on the health of soil, which is a measure of a complex set of biological, chemical and physical interactions driven by microorganisms. Effective microorganism increases the beneficial microbial population in the soil for sustainable crop production. Effective Microorganisms are mixed cultures of beneficial naturally-occurring organisms that can be applied as inoculants to increase the microbial diversity of soil ecosystem. They consist mainly of the photosynthesizing bacteria, lactic acid bacteria, yeasts, actinomycetes and fermenting fungi.
