Nitrogen and Phosphorous Filter Trials

Research & Monitoring – With Descriptor

About the project

Living Water has contributed to a DairyNZ project involving the installation of two nutrient mitigation filters. NIWA (National Institute of Water and Atmospheric Research) has installed the filters – one for Nitrogen and one for Phosphorous – to assess their ability to remove nutrients from water flowing through farm land dominated by tile drainage. The goal is to assess filter performance at the paddock scale and provide certainty about the efficiency and cost-effectiveness of these solutions.

We invested in this project because of its potential to provide a practical solution for farmers to reduce their impact on the environment and improve the quality of the water flowing into Waituna Lagoon.
