This research summarises cadmium concentrations from soil samples collected by the fertiliser industry between 2006 and 2015, and from soil samples collected by regional councils. Using these data, a statistical model was used to estimate soil cadmium concentrations on agricultural land within each territorial authority.
Elevated soil cadmium concentrations were primarily found in the Waikato and Taranaki regions, which have previously been identified as regions with higher soil cadmium concentrations.
The full report has been published in the New Zealand Journal of Agricultural Research.
