Exchangeable calcium data layer used in the creation of Land Environments of New Zealand (LENZ) classification. The classification layers have been made publicly available by the Ministry for the Environment (see data.mfe.govt.nz/layers/?q=LENZ for to access these layers).
This data layer is a measure of how much exchangeable calcium is held within the soil. The amount of exchangeable calcium defined in the data layer is derived by the soil information (from the NZLRI) and the mapped parent material. Four classes of exchangeable calcium, ranging from Low (1), through to Very High (4). The class defined as "0" signifies areas where there are no soil attributes recorded (i.e. high peaks of the Southern Alps).
Additional details such as discussion about the accuracy and reliability of the LENZ soil layers and the technical definitions of the categories in this layer are defined in the attached LENZ Technical Guide.
