Dept of Environment, Water and Natural Resources - Soil Salinity - Non-watertable
Non-watertable salinity (or dry saline land) is where soil contains elevated levels of soluble salts that are not associated with a watertable. Mapping shows the degree of non-watertable salinity, based on the most saline part of the map unit (provided it occupies at least 30%), while detailed proportion data are supplied for calculating respective areas of each non-watertable salinity class (spatial data statistics).

Dept of Environment, Water and Natural Resources - Soil Salinity - Non-watertable (magnesia patches)
공공데이터포털
Non-watertable salinity (or dry saline land) is where soil contains elevated levels of soluble salts that are not associated with a watertable. Magnesia patches occur where high concentrations of this salt extend to the surface and visibly affect plant growth. Mapping shows the proportion of land affected by magnesia patches, while detailed proportion data are supplied for calculating total areas of affected land (spatial data statistics).
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 - Soil Water Repellence
공공데이터포털
Water repellence, or non-wetting, due to coating of soil particles by waxy materials from the breakdown of plant debris can result in water beading on the surface, uneven wetting and large masses of soil remaining dry. Mapping shows the proportion of land affected and degree of water repellence, while detailed proportion data are supplied for calculating respective areas of each water repellence class (spatial data statistics).
Dept of Environment, Water and Natural Resources - Physical Condition of the Soil
공공데이터포털
Physical condition of soil provides an integrated view of various physical impediments to plant growth associated with surface soils, subsoils and other limitations (e.g. waterlogging, salinity, rockiness or steepness). Mapping shows the most limiting soil physical condition (provided it occupies at least 30% of a map unit), while detailed proportion data are supplied for calculating respective areas of each physical condition of soil 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 - Physical Condition of Surface Soil
공공데이터포털
Physical condition of surface soil mapping highlights areas where plant growth may be impeded due to poor surface soil structure, predominantly due to a condition known as hard setting. Mapping shows the proportion of land with surface soils susceptible to hard setting or sealing, while detailed proportion data are supplied for calculating respective areas of each physical condition of surface soil class (spatial data statistics).
Dept of Environment, Water and Natural Resources - Soil Waterlogging Susceptibility
공공데이터포털
Waterlogging susceptibility describes the degree and duration of impact to soils, and hence plants, arising from poor drainage. Mapping indicates the most severely waterlogged areas (provided they occupy at least 30% of a map unit), while detailed proportion data are supplied for calculating respective areas of each waterlogging susceptibility 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.
