EM Products

EM activates local and native microorganisms that live in soil and water and maximizes their natural power. Healthy soil and clean water are maintained by the diversity and balance of the community of microorganisms within them. EM solves many problems in agriculture, in the environment and more by restoring a healthy balance of microorganisms in ecosystems, thereby increasing their capacity for self-purification.

The beneficial effects of EM are realized when the groups of microorganisms, including lactic acid bacteria, yeast and phototrophic bacteria, activate native microorganisms in the environment and harness their intrinsic power.

Nowadays, in more than 100 countries around the world, EM is used in numerous fields including agriculture, animal husbandry, environmental purification and health care.

Here are some of our products, through which EM demonstrates its effects. In polluted rivers, species that cannot survive in a degraded environment die out and the ecosystem becomes degraded. Conversely, if the diversity of microorganisms is rich, nature’ s self-purifying ability is enhanced and clean water will return. The reason that EM can solve the problems it does is that EM restores a healthy balance of microorganisms in the ecosystem, thereby increasing its self-purification ability.


EM・1 is the fundamental product of EM. It comes in a liquid form and contains different groups of microorganisms, including lactic acid bacteria, yeast and phototrophic bacteria. Because of the co-existence of these microorganisms, EM・1 and the metabolites it contains are able to activate native microorganisms in various environments and conditions and in many different fields such as agriculture, animal husbandry, environmental purification and health care. EM・1 is also used to make EM Bokashi and EM Mudballs.

EM・1 is the original, authentic, Effective Microorganisms solution formulated by Dr. Higa. It was developed in the 1980s, long before microbiome science caught the world’s attention, and its effectiveness has been repeatedly demonstrated across the globe ever since. Currently, EM・1 is manufactured in more than 50 countries under the direct supervision of EMRO.

Secondary Products

In recent years, many researchers have been focusing less on the activity of single-strains of microorganisms and more on aggregates of microorganisms called microbiomes. In agriculture, it has become apparent that when soil microbiomes are healthy, they will enrich the soil. Healthy aquatic microbiomes will help maintain the environmental purification capabilities of rivers and other bodies of water.

Numerous secondary products have been developed using EM in many countries and in many fields, in accordance with demand. Each product is for a different purpose, some for large-scale agriculture and other for home gardening. EM can be applied in many ways and be incorporated into many types of products to suit your needs.
