Access to reliable data on soil cadmium (Cd) concentrations for soils that have received long-term inputs of phosphorus (P) fertiliser is important to help manage Cd in New Zealand agricultural systems. Two studies that analysed soil Cd concentrations in samples from the Winchmore long-term phosphate fertiliser trial suggested different trends in rates of Cd accumulation.
The aim of this study was to re-analyse soil samples previously analysed for Cd at the Winchmore trial, and also analyse new samples to help clarify the trend in soil Cd concentrations.
