Estimates of soil phosphate retention (P-retention; units: %) for the depth interval between 0 to 7.5 cm, covering all of New Zealand. Estimates are made on a grid where each grid cell has dimensions 1,000 m x 1,000 m (100 ha). The value at each grid cell is our best estimate of the mean P-retention across the area occupied by each grid cell. The layer...

Spatial estimates of gravimetric soil carbon (%) for the 0–7.5 topsoil layer, over the land surface of New Zealand. It was derived using gradient boosting regression from a range of environmental classification, national soil classification, and climate layers as explanatory variables. The model was calibrated on a large number of samples (approx. 17,000...

Rabbit numbers counted by pest destruction boards to measure the affect of control operations are used to assess the relationship between recorded elements of land resources (parent material, soils, vegetation, slope, erosion) and rabbit populations. The results of the study clearly confirm the often observed concentration of high rabbit populations on the...

Soil texture is the dominant texture class in the control zone (usually the upper 60 cm) of the soil profile as defined in Webb & Lilburne (2011). This layer is a "dissolved" representation of the soil texture attribute for S-map, where neighbouring S-map polygons have been combined if they have the same value of the attribute. Refer to document Smap...

Relative bypass flow is the potential susceptibility of water infiltrating at the soil surface to bypass the soil matrix as it drains through the soil. This is where the infiltrating water rapidly ‘short circuits’ the soil by percolating along preferential pathways (i.e., macropores, cracks, fissures, decayed-root channels). The vulnerability of land to...

The susceptibility of the soil to nitrogen leaching - the process whereby excess nutrients not held by the clay and organic matter complex of the soil leach beyond the root zone and contaminate groundwater. The susceptibility rating is based on the capacity of the soil to store water and the attenuation of nitrogen through denitrification associated with...
