What is EM

Category

Life on Earth depends on countless invisible microorganisms.

As the foundation of the ecological pyramid, they sustain the natural cycles that support all living things. The greater their diversity and abundance, the stronger and healthier ecosystems become.

EM (Effective Microorganisms) is a carefully balanced community of naturally occurring microbes selected for their positive impact on people and the environment. The key members include.

Lactic acid bacteria
Convert sugars into lactic acid, suppress harmful microbes, and create stable, low-odor environments. They support microbial balance in both soil and living organisms.
Yeast
Drive fermentation, producing amino acids and vitamins that feed other microbes and encourage cooperation.
Phototrophic bacteria (e.g., Rhodopseudomonas)
Harness light energy to break down harmful substances like hydrogen sulfide and ammonia, while producing antioxidants and bioactive compounds that help ecosystems recover.

Working together, these microbes form a powerful, symbiotic network that strengthens natural processes. EM also activates native microorganisms in soil and water, unlocking each environment's hidden potential.

Gently harnessing the power of nature

How EM Works

1. Fermentation of Organic Matter

EM transforms organic materials such as food waste, animal manure, and fallen leaves through fermentation, preventing foul odors and harmful byproducts, while producing nutrient-rich matter that enhances soil health.

2. Activation of Beneficial Microorganisms

During fermentation EM generates amino acids, enzymes, vitamin, and organic acids, These compounds stimulate microbes already living soil and water, creating a healthier microbial balance.

3. Restoring Environmental Balance

By suppressing harmful bacteria and odor-causing organisms, EM helps restore balance to ecosystems, leading to fertile soil, cleaner water, and healthier conditions for plants, animals, and people.

The Expanding Potential of EM: From Agriculture and Aquaculture to Environment and Wellness

More than 40 years have passed since EM was first developed. What began as a solution for agricultural use has now evolved into a technology applied across a wide range of fields.

In agriculture, EM activates soil microorganisms and enhances biodiversity, creating healthy, living soil that supports strong and pest-resistant crops.
In livestock farming, it helps maintain odor-free barns, improves animal health, and contributes to higher meat quality. In aquaculture, EM enables antibiotic-free farming and supports sustainable water circulation systems. It is also used to restore river ecosystems, recycle food waste, and alleviate sick building syndrome in construction.

EM's benefits also extend to the field of wellness as well. EM based products, such as EM・X GOLD, help balance the gut environment and promote overall health and wellbeing.

Worldwide

EM Around the World

EM is now produced in more than 50 countries and used in over 130, across climates ranging from the tropics to the Arctic. For more than 40 years, its benefits have been confirmed in agriculture, environmental restoration, and daily life.

In farms, households, fields and waterways, EM Technology contributes to healthier communities and a more sustainable planet.

EM is a trademark and a brand name owned by EM Research Organization,
and is used on a variety of products.

EM Glossary

  • Activated EM • 1 (also called EM Activated Solution / EMAS)
  • Rice Rinse Water EM Fermented Solution
  • EM Bokashi
  • EM Mudballs
  • EM Compost

Activated EM • 1 (also called EM Activated Solution / EMAS)

A solution made by culturing EM microorganisms using EM • 1 as the starter, with molasses and water. It can be easily produced at home, making it a cost-effective way to use EM widely.

Rice Rinse Water EM Fermented Solution

A solution made by culturing EM microorganisms using EM • 1 as the starter, with molasses and rice rinse water.

EM Bokashi

A fermented material made by mixing rice bran with EM • 1 (or Activated EM • 1 / Rice Rinse Water EM Fermented Solution) and molasses.

EM Mudballs

Soil balls made by mixing soil with EM • 1 (or Activated EM • 1 / Rice Rinse Water EM Fermented Solution), molasses, and EM Bokashi, and fermenting the mixture.

EM Mudballs

A compost made by fermenting organic matter with Activated EM • 1. With Activated EM • 1 or EM Bokashi, almost any kind of organic matter can be composted.
