McEwan Ag-Nutrients Ltd
Based in: Waikato

I has been involved with farm nutrient management for 20 years and have experience with all dairy farming systems and the associated effluent systems that are applicable to that particular farm. Effluent system design is not just about a big storage solution, there are a variety of options that should be assessed to ensure a fit for purpose outcome. I operate independent of any product supplier. 

My qualifications are 

  • Intermediate & Advanced Sustainable Nutrient Management qualifications from Massey
  • Effluent System Design & Management also from Massey
  • Effluent Pumping & Hydraulics from Massey

This experience & these qualifications are all applied to consenting processes for regional councils and as an independent operator of the Overseer Nutrient Budget programme.
