EM™ Research

We have conducted trials in New Zealand regularly over the past 17 years with great results. In addition, EMs prolific use around the world also gives us access to trial data from a variety of countries and crops which gives us a picture of the overall efficacy of EM.  This ensures that we always receive the latest and the best expertise and thus we can remain the market leaders in terms of development and research in the field of Effective Microorganisms and biological inoculants.
