About EM

EM is a sustainable microbial inoculant that achieves synergistic effects by combining beneficial microorganisms which exist in nature. EM activates local and native microorganisms that live in soil and water to boost performance. One of the strengths of EM is that it is a diverse combination of microbes, and this gives it versatility in terms of a wide scope of applications that it can be used on. EM was initially developed to improve soils and enhance crops but has evolved to benefit a wide range of areas and is used in numerous fields including agriculture, animal husbandry and environmental purification in more than 100 countries around the world.

Product Uses


How To Renew Your Old Garden Soil

Soil conditioners like EM are full of helpful microbes that are beneficial to plants. In order to grow healthy vegetables and beautiful flowers, it may be necessary to improve your garden bed. Soil conditioners are added to the soil to improve physical properties, such as water retention, permeability, water infiltration, drainage, aeration, and aggregation.

Farmer and Soil Consultant Conduct a Soil Assessment and Worm Count

Mark Nichols, Northland Farmer, and Avoca Soil Consultant , Tony Johnston do a soil assessment and worm count to look at the effect of EM on his soil.

Compacted Soils and the Effect on Soil Biology

Coming out of winter and into spring here in NZ, there is a real threat of pugged and compacted soils. High stock densities, especially over winter on feed crops combined with prolonged rainfall leave soils vulnerable to pugging and compaction. Pugging and compaction reduce the soils volume; this reduction lowers soil productivity and environmental quality not to mention the effect on microbes

Improved Soil and Pastures in Northland - Comparison Pictures

Recently I was lucky enough to visit a great farm in Northland. The past season was the first season where EM has been included into his program and they have started to see some great benefits. Currently it is very wet but they are starting to reap the benefits of this soil program as the drainage is impressive and the soil structure has improved a lot.
