What is EM™

EM™ is the abbreviation for Effective Micro-Organisms.
EM is a combination of useful regenerative micro-organisms that exist freely in nature and are not manipulated in any way.
This mixture increases the natural resistance of soil, plants, water, humans, and animals.
EM considerably improves the quality and fertility of soil as well as the growth and quality of crops.

The possibilities for using EM are numerable and include the following:

EM consists of 80 different kinds of effective, disease-suppressing micro-organisms. Each of these effective micro-organisms has a specific task. In addition, these micro-organisms enhance each other's working. This means that synergy occurs!
The micro-organisms are naturally existing and are not modified or manipulated in any way and are cultured according to a specific method. Some of which are known to produce bioactive substances such as vitamins, hormones, enzymes, antioxidants and antibiotics that can directly, or indirectly enhance plant growth and protection.
The micro-organisms in EM have been used medicinally and in food processing for many years, which gives an indication as to how safe hey are to use.


EM consists of the following five families of micro-organisms:

  1. Lactic acid bacteria: these bacteria are differentiated by their powerful sterilising properties. They suppress harmful micro-organisms and encourage quick breakdown of organic substances. In addition, they can suppress the reproduction of Fusarium, a harmful fungus.
  2. Yeasts: these manufacture anti-microbial and useful substances for plant growth. Their metabolites are food for other bacteria such as the lactic acid and actinomycete groups.
  3. Actinomycetes: these suppress harmful fungi and bacteria and can live together with photosynthetic bacteria.
  4. Photosynthetic bacteria: these bacteria play the leading role in the activity of EM. They synthesise useful substances from the secretions of roots, organic matter and/or harmful gases (e.g. hydrogen sulphide) by using sunlight and the heat of soil as sources of energy. They contribute to a better use of sunlight or, in other words, better photosynthesis. The metabolites developed by these micro-organisms are directly absorbed into plants. In addition, these bacteria increase the number of other bacteria and act as nitrogen binders.
  5. Fungi that bring about fermentation these break down the organic substances quickly. This suppresses smell and prevents damage that could be caused by harmful insects.

Effective Microorganisms, or EM is one of the most popular microbial technologies being used world-wide now and EM products have been on the market since 1983 in Japan.

EM comes in a liquid form and consists of naturally-occurring beneficial microorganisms. EM is now produced in many countries and uses the strains of the appropriate microorganisms that occur naturally to the region.

Throughout the world, EM applications are made in the farming, livestock, environmental cleanup (polluted waterways, lakes and lagoons), and health industries.

What EM is not, is harmful, pathogenic, genetically-engineered/modified (GMO), nor chemically-synthesized. Neither is EM a drug or fertiliser.
