Dept of Environment, Water and Natural Resources - Soil Salinity - Non-watertable (magnesia patches)
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 - Non-watertable
공공데이터포털
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 - 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 - 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 - 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 Sodium Toxicity (depth to toxic layer)
공공데이터포털
High natural levels of sodium, that are toxic to some plants, are typically associated with deep subsoil sodicity, high pH, high boron and moderate salinity, and occur mostly in drier parts of the state. Mapping shows the depth to sodium toxicity of the most severely affected portion of the map unit (provided they occupy at least 30%), while detailed proportion data are supplied for calculating respective areas of each depth to sodium toxicity class (spatial data statistics).
Dept of Environment, Water and Natural Resources - Soil Surface Carbonate
공공데이터포털
Surface carbonate often occurs as finely divided particles which reduce nutrient availability to plants and retard the degradation of some herbicides. Mapping shows the proportion of land with calcareous surface soils, while detailed proportion data are supplied for calculating respective areas of each surface carbonate class (spatial data statistics).
