Dept of Environment, Water and Natural Resources - Soil Salinity - Watertable induced

공공데이터포털

This assessment refers to salinity which is linked to watertables. Soluble salts in soils affect plant growth by restricting water uptake. Salinity has varying degrees of severity and distribution. Mapping shows the degree of salinity and the proportion of land affected by discrete highly saline seepage, while detailed proportion data are supplied for calculating respective areas of each watertable induced salinity class (spatial data statistics).

Dept of Environment, Water and Natural Resources - Scalding (soils)

공공데이터포털

Scalding refers to land, primarily in low rainfall environments, where the surface soil has been eroded to expose sub-surface material that is unsuited to plant growth. Mapping shows the proportion of land affected by scalding, while detailed proportion data are supplied for calculating total areas of affected land (spatial data statistics).

Dept of Environment, Water and Natural Resources - Flooding Susceptibility (soils)

공공데이터포털

Susceptibility to flooding imposes a serious limitation on land especially where infrastructure is required. Mapping shows the proportion of land susceptible to flooding, while detailed proportion data are supplied for calculating total areas of susceptible land (spatial data statistics).

Dept of Environment, Water and Natural Resources - Soil Alkalinity

공공데이터포털

Alkalinity is usually an inherent characteristic of soils, and alkaline soils are largely confined to areas with less than 400 mm annual rainfall. Mapping shows surface and subsoil alkailinty, while detailed proportion data are supplied for calculating respective areas of each alkalinity class (spatial data statistics).

Dept of Environment, Water and Natural Resources - Depth to Watertable (soils)

공공데이터포털

Depth to watertable mapping highlights land where watertables may be sufficiently shallow on a seasonal basis to affect plant growth. It is intended to describe soil conditions for plant suitability and is not intended to be a literal map of watertable levels, which will change over time. Mapping shows the shallowest depth to watertable observed (provided it accounts for at least 30% of the map unit), while detailed proportion data are supplied for calculating respective areas of each depth to watertable class (spatial data statistics).

Dept of Environment, Water and Natural Resources - Surface Soil Texture

공공데이터포털

Surface texture (which refers to approximate clay content) influences many important soil qualities such as waterholding capacity, fertility and erodibility. Mapping shows the most common surface texture within each map unit, while more detailed proportion data are supplied for calculating respective areas of each surface soil texture class (spatial data statistics).

Dept of Environment, Water and Natural Resources - Soil Gully Erosion

공공데이터포털

Gully erosion refers to areas affected by erosion channels (more than 30 cm deep) originating from natural watercourses or artificial drainage features. Mapping shows the proportion of land affected by gully erosion, while detailed proportion data are supplied for calculating total areas affected (spatial data statistics).

Dept of Environment, Water and Natural Resources - Surface Rockiness (soils)

공공데이터포털

Surface rockiness mapping describes the overall amount of surface stones and outcropping rock, in the context of management implications for farming. Mapping shows the estimated average degree of rockiness, while detailed proportion data are supplied for calculating respective areas of each surface rockiness class (spatial data statistics).

Dept of Environment, Water and Natural Resources - Soil Acidity

공공데이터포털

Soil acidity mapping highlights land where acidification due to normal farming practices is, or could become, a significant problem. Mapping shows surface and subsoil acidity, and surface buffering capacity (ability to withstand pH changes), while detailed proportion data are supplied for calculating respective areas of each soil acidity class (spatial data statistics). Also available for download in the Australian Soil Resource Information System format: Surface Soil Acidity; Subsurface Soil Acidity and Subsoil Acidity.

Dept of Environment, Water and Natural Resources - Soil Available Waterholding Capacity

공공데이터포털

Available waterholding capacity refers to the potential volume (on a per unit area basis, expressed in mm) within the rootzone of a soil that can be filled by rainfall or irrigation, and is available to plants (i.e. not including moisture help by soil matrix suction). Assessments are based on the rootzone of wheat plants. Mapping shows the estimated average available waterholding capacity, while detailed proportion data are supplied for calculating respective areas of each available waterholding class (spatial data statistics).
