Owl Farm case study - Nitrogen management

This page from Owl Farm, a demonstration dairy farm in the Waikato, covers its strategy for managing nitrogen fertiliser and effluent to reduce modelled nitrogen loss. It uses Overseer to track nitrogen movement through the farm system and sets out the changes made over recent seasons, including lower fertiliser rates, timed applications and an enlarged effluent spreading area.

It also covers the plantain and clover pastures the farm has planted to cut nitrogen losses, and the infrastructure built to store and irrigate effluent across more of the farm.
