A long term trial (Cheng & Yingchun, 2012) over 11 Years conducted at China Agricultural University’s Qu-Zhou experiment station found that the long-term application of EM compost gave the highest values for the measured parameters and the lowest values in the control plot. The application of EM in combination with compost significantly increased wheat straw biomass, grain yields, straw and grain nutrition compared with traditional compost and control treatment. Wheat straw biomass, grain yields, straw and grain nutrition were significantly higher in compost soils than in untreated soil. This study indicated that application of EM significantly increased the efficiency of organic nutrient sources.

This field trial was designed to determine the effectiveness of EM treatment variations against competitor products and an untreated control on Wheat in Aylesbury.
Cropmark have independently harvested the trials using a precision plot harvester. This was performed blindly, just numbers, no treatment description. They provide plot weights and grain weights.
Data was then analyzed statistically by UC student, Brennan Fayen.

Table 2: Average Plot Height and Vigor measured on 17/12/20.
In mid-December the plots were assessed for growth, by doing a vigor score (1-10) and measuring plant height. This data has not been statistically analyzed, but clearly demonstrated that EM plant stimulant was the best looking treatment with corresponding height advantage (Table 2).
Table 3: Comparing a range of foliar products on the yield of wheat (t/ha) Grain Yield
All of the foliar treatments which included five EM based foliar products and two micronutrient based foliar products, recorded significantly higher yields than the control (LSD5) (Table 3).
Table 4: Comparing a range of foliar products, on the Grain Weight by volume (kg/HL) .
All foliar products recorded high grain weights than the control (LSD5).
EM based foliar products performed very well against a control treatment.
EM based products generated significant products over the control
