Abstract or Summary

Cadmium (Cd) is a toxic element mainly originating from phosphate fertiliser application in New Zealand (NZ) agricultural land. Recent research showed a high concentration of Cd in NZ soils due to the application of Nauru-derived phosphate fertilisers which are high in Cd content. Since 1997, the industry changed the main source of phosphate fertilisers from Nauru phosphate rocks to a mix of new sources with lower amount of Cd. In this research, we applied the isotope technique to trace the contributions of old and new fertilisers in increasing the amount of Cd in NZ soil, plant, surface, and groundwater.
