EM-1® is not a pesticide and contains no inorganic chemicals.

EM is a microbial inoculant that works as a bio-control measure in suppressing and/or controlling pests through the introduction of beneficial micro-organisms to soil and plants.

Pests and pathogens are suppressed or controlled through natural processes by enhancing the competitive and antagoniostic activities of the micro-organisms in the EM inoculents.

EM-1® can be used to innoculate plants, water and soil to achieve beneficial results in growth and plant immunolgy.

It can be spayed on the soil as a pre-planting treatment, used to inoculate seeds or transplants , and applied to growing crops as a foliar spray or through irrigation systems.


EM-1® is useful in growing nursery crops, container grown plants and hydroponics.

After crops are harvested EM-1® is used to breakdown crop residues in green manures.

Simple test results of growth increase in pot plants.

You can add a 2% ratio of bokashi to your potting soil and irrigate with EM enhanced water 1:1000 to achieve good results.

EM products that can be used in horticulture:


EM consists of many different kinds of effective, disease-suppressing micro-organisms. Each of these effective micro-organisms has a specific task. In addition, the micro-organisms enhance each other’s working. This means that synergy occurs!

The micro-organisms are collected in the open air, are not modified or manipulated in any way and are cultured according to a specific method.

EM consists of the following five families of bacteria:

    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 synthesize useful substances from 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.

Value and domination principle of EM

What makes EM unusual is the combination of aerobic and anaerobic micro-organisms. The meaning of aerobic is living with oxygen and anaerobic means living without oxygen. The scientific world has always accepted that these two groups could not possibly live side-by-side because the conditions for survival are completely opposite. Both groups, however, naturally occur in the soil.

Effectivity of EM

EM is a living substance and does not work in the same manner as antibiotics or a chemical substance. EM increases the population of beneficial micro-organisms. There is absolutely no way that the same effect can be achieved with chemical fertilizers and agricultural pesticides. Artificial fertilizers act on the salt and acid content, which can have a negative effect on the environment.

EM does not kill other living things. It is a probiotic and works by a mechanism that eliminates harmful insects and at the same time stimulates the increase and distribution of beneficial insects. The advantage of this process is that no new anomalous insect species with even higher increased resistance will develop.

The effect of EM is accumulative. Results are dependant on application and area of use. Dependending on application results may be noticeable after a few days (as in eliminating foul odour), or after several months (in the case of soil rejuvenation).

EM-5: A mixture of bacteria, vinegar and spirits (alcohol) that acts as an insect repellent. Insects will be driven away by a thorough soaking with EM-5.

EM-FHE: Fermented Herb Extract. A bacterial preparation based on plant extracts. This product strengthens plants and increases immunity. Due to the large number of micro-elements and micronutrients, this product has already proved its worth as a plant foliage nutrient.

EM Ceramics

The EM ceramics are placed in water and have an immediate effect on the water through a process of resonance. The longer that the EM ceramics remain in the water, the better the results will be. The recommended amount of EM ceramics depends on the amount of water. The EM ceramics must amount to one thousandth part of the water mass. Therefore, one cubic metre of water will require one kilogram of ceramics. Where larger and constant masses of water are concerned, such as ponds or swimming pools, the amount of ceramics can be reduced by ten to twenty percent. Irrigation water supply tanks can be treated with EM Ceramics to improve water quality and a significant growth increase and disease resistance is noticable in plant cultivation.

Hort-Plus: A plant nutrient with a homeopathic base. Agri-grow takes effect by reaching even the tiniest particles. As with the other products mentioned above, it is equally harmless for both human and plant life.

Agrisanum: This product is unique, consisting of Bentoniet clay minerals and enriched with organic Germanium that does not contain any chemical pesticides. Agrisanum strengthens plants from germination to harvest by providing natural immunity to viruses, fungi and parasites as well as the harmful effects of flies affecting carrot, leek, onion and cabbage crops.

Grow-Best: A completely organic fertilizer for your vegetables, flowers and lawn. This consists of mealworm fertilizer, castor oil shoots, clay minerals, basalt meal, seaweed and bacteria cultures. Mest-Best forms the bulk of the much desired clay-humus complex which leads to a good soil consistency. Liquid and nutrient materials are retained.

Edasil clay minerals: This product has a tremendous swelling capacity due to the specific plate-like structure and is therefore able to bind together a large amount of water and nutrients. In addition, it contains all of the essential micro-elements in a balanced dose.

Ostrea seashell lime: One advantage of sea shell lime is that its effect is long-lasting and can therefore avoid pH values that are either too high or too low. The pH value is therefore influenced over a fair period of time which results in optimal plant growth.

Bokashi: This is a bran-based fermented organic material based on brewer’s grains for animals, plants and soil. Bokashi is a source of nourishment for micro-organisms that grow in the soil. These establish themselves on a permanent basis in the soil, multiply and then dominate the harmful bacteria, viruses and fungi that are present.

Fermentation tanks with heating element and airlock: Plastic cask with electric heating element for a volume of 30 to 60 litres for fermenting EM-1 into EM-A. (Illustrated, right).

DVD Film “Life in the soil”:

This film encourages people to think about how we are living! The healthy soil is portrayed as an extremely complex living organism. The soil life is filmed in wonderful natural colours with the use of an electronic microscope. The message coming from the film is clear: recognise the importance of sustainable agriculture and learn the nature of the soil life in order to completely understand it.

The soil is a vulnerable living organism. In order to ensure a sustained productivity and stability, the soil must be continually fed. The film covers various aspects such as an introduction to soil science, soil microbiology, sustainable agriculture, agricultural ecology and environmentology. The film is suitable for all levels of agricultural colleges and universities. The film is also appealing for the general public and of course the keen gardener.
