World Reference Base for Soil Resources (WRB)

New Zealand and the WRB

The WRB is not intended to be a substitute for national soil classification systems, but rather to serve as a common denominator for communication at the international level.

Applying the WRB to New Zealand soils is still in its infancy, and the USDA Soil Taxonomy is used in most cases for communicating New Zealand soil types internationally. A NZSC/WRB correlation table is currently being prepared and is expected to be available in the second half of 2018.

ISRIC–World Soil Information have used digital soil mapping techniques to produce a global 1km resolution map of WRB reference soil groups. The map is available from the SoilGrids web mapping portal, and is being updated regularly.
