This layer shows the coverage of S-map polygons, labelled with their Soil mapunit – a unique identifier of one or more polygons with the same soil information.
The S-map primary map layer of soil classes (i.e. delineated areas that are labelled with the soil family names) is no longer freely available to commercial users. Access to this data and associated soil attribute data for commercial use is by negotiation - contact Graeme Anderson (andersong@landcareresearch.co.nz).

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.

Soil drainage is a relatively simple classification of the soil profile that describes the likelihood of seasonal wetness (Webb & Lilburne 2011). It is based on the occurrence within specific depths of redox segregation and low chroma colours indicative of waterlogging and reduction (Milne et al. 1995). This layer is a "dissolved" representation of the soil drainage attribute for S-map soils, where neighbouring S-map polygons have been combined if they have the same value of the attribute.

Soil depth is defined according to a traditional agronomic concept of soil depth (Webb &
Lilburne 2011). Note that while the layer defining soil depth may cause some restriction in root penetration, it does not necessarily define the base of the potential rooting depth. This layer is a "dissolved" representation of the soil depth attribute for S-map soils, where neighbouring S-map polygons have been combined if they have the same value of the attribute.

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 bypass flow is based on soil classification, soil structure, and soil attributes that promote ponding. It does not take into account climate or land use.

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 anaerobic conditions. It does not take into account the climate or land use but is limited to the effect of the soil characteristics.

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 was generated using a quantile regression forest which was fitted using a number of environmental datasets including soil parent material, topography and climate layers. Saunders WMH 1965.
