New Zealand's Environment Reporting Series: The Ministry for the Environment and Statistics New Zealand
We report on seven soil properties from 1996 to 2018: pH (a measure of acidity), Olsen phosphorus (a measure of fertility), total carbon, total nitrogen, and anaerobically mineralisable nitrogen (measures of organic reserves), and macroporosity and bulk density (measures of physical status). These are assessed across nine land uses. We report the proportion of sites above, below, and within soil quality target ranges for each of the seven soil quality indicators by land use, as well as by soil order.
More information on this dataset and how it relates to our environmental reporting indicators and topics can be found in the attached data quality pdf. Technical report links for this dataset are https://environment.govt.nz/publications/soil-quality-data-for-land-2021 and https://environment.govt.nz/publications/soil-quality-and-trace-element-dataset-trend-analysis
