EM Balance is designed to enhance the activity and longevity of microbial activity in the soil. EM Balance is a product which combines beneficial soil microorganisms (EM), Amino Acids, Plant Growth Stimulants, and complex food sources in the form of Fish hydrolysate and Humic and Fulvic acid. This combination is designed to stimulate bacteria and fungi, unlock soil bound nutrients and enhance the uptake of fertiliser inputs.

Why Activate Soil Biology

Scientific trials and soil surveys show that active soil microbes are a key component to healthy soils and important to ensure your soil performs. These beneficial fungi and bacteria improve nutrient availability and protect the crop from disease. We also know that as beneficial microbial populations decline, disease increases. The components in EM Balance contain both EM which is a proven soil activator – stimulating and adding to the resident microbial population, and microbial food sources designed to activate soil microbes by feeding them to make a difference to your soil and crop. The main decomposition pathways in soil are either bacterial-based or fungal-based. Fungi and bacteria are the principle agents for the cycling of nutrients. 

The key benefits of using EM Balance are

  • Increasing soil microorganisms
  • Feeding the soil microbiome
  • Increasing the organic matter content of the soil
  • Enhancing nutrient uptake
  • Boosting plant hormone responses
  • Convert nutrients efficiently into plant available compounds
  • Improving soil structure
  • Boosting Earthworms
  • Providing readily available Amino acids
  • Stimulating plant root growth
  • Suppressing disease

    Customer Testimonials

    • “The results have been amazing. We have seen exceptional clover growth, the worm population has increased a lot and they are very healthy.“

      Tim Hawke Sheep and Beef Farmer, Canterbury
    • "EM is something I swear by in the garden. I saw the difference it made in my mum’s vege garden and I wanted the same. You can use it as is, or mix it with seaweed, Neem, bactur, copper, or whatever you use to feed and manage your garden. I use EM Foundation product to prep my soil for planting, and EM Foliar Enhance for quick pick me up feeds through the season. Organic and natural."

    What is EM?

    Effective microorganisms or EM are mixed cultures of beneficial microorganisms that can be applied as inoculants to increase the microbial diversity of soils and plants which, in turn, can improve soil health, and the growth, yield, and quality of crops.

    How does EM actually work?

    There is documented scientific evidence to indicate that EM cultures can

    (a) suppress soil-borne pathogens,

    (b) accelerate the decomposition of organic wastes and residues,

    (c) increase the availability of mineral nutrients and useful organic compounds to plants,

    (d) enhance the activities of beneficial, indigenous microorganisms, e.g., mycorrhizae, 

    (e) fix atmospheric nitrogen, and

    (f) reduce the need for chemical fertilisers and pesticides. 


    Actually, EM tends to simulate the "rotation effect," a term used by agronomists to describe the regeneration of beneficial soil microorganisms and suppression of harmful ones which results from crop rotation.

    Is EM an organic product?

    Yes, EM is certified organic by BioGrow NZ and can be used in all types of organic systems. 

    What can EM be used for?

    EM has a huge range of uses around the home, garden, farm, business, or industrial zone. Today EM is used in many systems pertaining to agriculture and environmental management. These range from crop and animal production systems, to livestock and aquaculture units. EM is used widely in environmental management for decomposition and more importantly for recycling of wastes, both solids and liquids.

    The application and use of EM technology in NZ is wide and varied:

    • From crops like peas, wheat, linseed to onions, potatoes, carrots and beans.
    • From sheep, cows and deer, to pigs and chickens
    • From wine grapes and olives to saffron and lavender
    • From recycling food waste in restaurants and schools back to gardens
    • From household food waste to larger office blocks and Universities collecting lunchtime food waste.
    • From small composting toilets in holiday homes to large composting toilets in mountain chalets for trampers and mountaineers.
    • From controlling odours at commercial and large municipal composting sites to controlling odours and improving water quality at vineyards treating their own wastewater.

    Whilst initially the use of EM was confined to Agriculture, in recent times the growth sector has been vineyards and waste management. Visit the industries section of this website to find out more about EM's uses.
