Upper Waikato nutrient efficiency study

TR 2014/18

Report: TR 2014/18

About this report

In 2006, Waikato Regional Council identified that agricultural practices were contributing to rising nutrient levels within the region's waterways. In response, they launched a three-year intensive policy implementation process, the Integrated Catchment Management (ICM) pilot project. The objective of the pilot project was to gain an understanding of nutrient management in the farm setting and investigate the potential effectiveness of ICM approaches in achieving sustainable improvements in water quality.

This report assesses the current nutrient use efficiency of a selection of farms in the Upper Waikato Catchment, and identifies options for further efficiency gains and their associated costs to the farm business.
