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.

Product Uses


Breaking down agricultural chemicals by EM

Due to agricultural modernization, we are currently faced with various problems by agricultural methods based on machinery, chemical fertilizers and agricultural chemicals that have been policy-driven after the war . After spraying, pesticides are mixed into water systems in the environment such as rivers, lakes, oceans and groundwater via various routes, causing environmental pollution.

EM Heavy Metal Suppressing Effect

In recent years, heavy metals have leached out into industrial waste from landfill sites and soil, and groundwater and the like are contaminated in many situations. Heavy metals such as Cd (cadmium) present in the soil are absorbed by crops, and if they are eaten for a long period, they accumulate in the body and adversely affect health. We look at whether EM can suppress Cd in crops.

Effect of EM on P Solubility and Uptake to the Plant

Phosphorus is the second essential macronutrient for plant growth, which plays a vital role in transfer of energy within the various parts of plant and root development for higher water and nutrient use efficiency. This post looks at the impact EM has on P in the soil, focusing on uptake and available P post harvest in addition to total yield.

Using EM for Disease Protection

EM introduced by Dr Higa initially was designed for improving soil quality and to speed up organic matter breakdown. Following widespread success in foliage applications boosting plant growth more time, effort and trial work has followed looking at controlling pests both insects and disease.
