Analysis of Five Different Fodder Beet Trials Across Four Years
These trials looked at using EM in both conventional and biological systems (Daly M. J., EMNZ Fodder beet Trial 2014) (Daly M. J., EMNZ Fodder beet Trial Ashcroft 2015) (Daly M. J., EMNZ Fodder beet Trial Seaton 2015) (Daly M. J., EMNZ Fodder beet Trial 2016) and were conducted in Canterbury, New Zealand on Fodder beet. Fodder beet is a crop that has become popular due to its yields and as an important part of dairy cow winter feeding systems. The trials were analysed by Dr Tim Jenkins (Independent Scientist), a summary of the results is as follows:
The trials conducted from 2014 – 2017 showed great results with an average increase in yield of 19% across 5 different trials.
EM treatments gave a significant increase over control.
Nitrogen enhanced EM (EMN-RTU), looks promising.
Reducing N inputs by 50% and combining EM looks to be a viable option as half rate of N with EM performed as good or better than a full rate

EMNZ Kale Trial
This replicated trial was conducted in Canterbury, New Zealand on Kale and showed a significant result was gained when EM was applied over a fertilised control. The EM treatment gave a 6% increase in yield.

Maize Trial 2015
This replicated trial (Daly M. , 2015) in Canterbury, New
Zealand was designed to determine the effectiveness of EM treatments, against a control on Maize, at Ashcroft Farm at Carew. The aim of this trial was to test EM on Maize yield, and in particular compare a number of variations of EM, including some combinations with Nitrogen.
EM gave a significant and economic yield response when applied to a Maize Crop
EM Soil & Crop, our standard recommended product, was the best performing treatment
EM with a half rate of N, performed better than a full rate of N not containing EM
