Feeding the world’s growing population

New Zealand’s reputation as a quality food producer is growing.

Optimising food production

Over the next 50 years farmers around the world will need to produce more food than has been grown over the past 10,000 years.

Best use from a limited resource

Fertiliser helps farmers produce food efficiently by replenishing the soil. But fertiliser needs to be used responsibly.

Responsible and sustainable nutrient management

The Fertiliser Association invests in research and tools to ensure farm profitability while minimising nutrient losses to the environment.

The Fertiliser Association of New Zealand promotes and encourages responsible and scientifically-based nutrient management.

Analysis of samples from the Winchmore long-term fertiliser trial for total soil cadmium contents

Col Gray, Rich McDowell, Alasdair Noble
Completed November 2017

Introduction

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.
