EM-1® is the original and authentic Effective Micro-organisms (EM) discovered and formulated by Dr. Teruo Higa.

EM-1® is an all-natural probiotic for plants and soils. It is a natural, safe technology with many applications around the garden, agriculture, animal husbandry, environmental and water treatment, and health care.

A certified organic input, EM-1® can be expanded by the user to increase the product volume 20 fold, making it a low-cost microbial input.

The combination of microbes in EM has a reviving action on an ecosystem and is completely safe to use. In the soil, EM will function by increasing the beneficial microbes which will improve soil health and function. EM will also improve fertiliser effectiveness by reducing leaching and improving plant availability leading to increased performance in your farming system. In a waste management system, EM will control odours and breaks down organic matter in the form of sludge and inorganic deposits to revive the function of a waste system.

EM-1® Concentrate can also be combined with other products such as liquid fertiliser, and other microbial food sources to enhance the EM effect.

EM-1® is completely free of GMO-altered microbes and contains only carefully selected soil microbes. The preparation is produced in a laboratory environment with high purification requirements. Activated EM-1® is sold under the product name Actiferm and is available in everything from 2L Bag in Box to 1000 L IBC on pallets.


  • Improves the chemical, physical and biological properties of the earth.
  • Purifies water.
  • Increases crop production and reduces dependence on pesticides and fertilizers.
  • Activates germination, flowering, fruiting, maturation, and root development.
  • Reduces the appearance of diseases by an increase in the general hardiness of plants.
  • Increased uptake of organic nutrients available in the soil.
  • Provides shorter rotation time when composting etc.

How to use

  • EM1 Concentrate should be enhanced and expanded by a secondary process using equal parts of molasses (LINK) and water. This process will expand EM-1 20 times making it very cost-effective.
  • If you feel you are not ready for making your own we have a cost-effective, less time-consuming way of using Actiferm 

When to apply

  • Apply at important plant growth stages
  • Apply with fertiliser to enhance effectiveness
  • Apply when incorporating crop residues and composting waste
  • Apply to effluent and wastewater for odour control and effective treatment
  • Apply to Septic Tank Maintenance, keeping content liquid and odour free.
EM1 Concentrate can be used as supplied or can be expanded before use (see Preparation)
  • Soil and Plant Treatment: Apply from 5-20 Litres per ha diluted with water
  • Garden Treatment: Use at 1% with water as a foliar or soil application
  • Compost Treatment: Apply 2-3 Litres per cubic metre
  • Water Treatment: Add EM at between 1/1000 and 1/10000 of water volume
See more information during use and dosage for Actiferm.
  • A solution EM-1® can be given with 1-10 liters/hectare. An even spread is recommended.
  • In growing crops, 1% solution can be given.
Mix of 80 micro-organisms Contains EM (Effective Microorganisms)
  • Store dark and cool.
  • EM-1® lasts one year in unbroken packaging.
  • Preferably should be used within six months of opening.
  • Activated EM® should be used within one month.
  • At warmer temperatures gas formation can take place in the package, corrected by screwing the lid on and off.

EM® technology

The EM® technology is based on a group of natural soil microbes that interact and together effectively degrade and mineralise organic matter. The group consists of photosynthesis bacteria, lactic acid bacteria, and yeast fungi. In specialised languages, the technique is called microbial consortium technology, i.e. a group of different organisms that through collaboration become more stable and efficient. In the soil, EM® stimulates other benign microbes that release nutrition and interact with the plant.

Prof. Teruo Higa

The European Championship® was developed by Prof. Teruo Higa of the University of Ryukyu in Okinawa, Japan. EM® technology has gained worldwide distribution and is used in agriculture, cultivation, animal husbandry, water treatment, waste management, recycling, and health.

EM® product range

Many secondary products have been developed with EM® in many countries and in many areas. Each product is for different purposes, some for large-scale agriculture and others for gardening. EM® can be applied in many ways and integrated into many types of products to suit your needs.
