EMNZ Replicated Field Trials

  •  

    Kale Field Trial

    The results showed a statistically signi cant increase in yield was achieved by using Plant-Stim, EM Soil & Crop and EM Amino

    Trial Report
  •  

    Multi-Cut Lucerne Field Trial

    Plant-Stim® significantly increased early-season growth, improved regrowth between cuts, and delivered a substantial increase in total seasonal production.

    Trial Report
  •  

    Carrot Field Trial

    Both Plant-Stim and EM Balance increased carrot yields substantially compared to the untreated control.

    Trial Report
  •  

    Potato Field Trial

    Both Plant-Stim and EM Balance improved yield compared to the control

    Trial Report
  •  

    Onion Field Trial

    All EMNZ treatments gave a significant and economic yield response when applied to an Onion Crop.

    Trial Report
  •  

    Oats Field Trial

    This field trial demonstrates that EMNZ biostimulants can have a significant effect on oat yield, suggesting their potential as valuable tools for improving crop performance.

    Soil Biology

    International EM research has shown improvements in microbial activity, humification, enzyme activity and soil health indicators.

    Trial Reports
  • Nutrient Cycling

    Research supports the role of EM systems in nutrient transformation, microbial activity and fertiliser efficiency.
