What the Winchmore Trials Teach Us About Fertiliser and Pasture
This lesson explores the Winchmore Trials, one of New Zealand’s longest-running fertiliser research programmes. Dr Will Talbot, Scientific Officer, explains how different rates of superphosphate affected pasture production, species composition and clover content over decades, and what happened when fertiliser was later withheld. A practical look at how long-term science underpins modern fertiliser recommendations.
