Biophysical Regions of Southern South Australia (soil landscapes)
Biophysical Regions represent the largest grouping of Soil Landscape Map Units within the SA soil and land mapping hierarchy. These cover broad geographical areas, recognisable... -
Soil Salinity - Watertable induced
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... -
Land Use Potential for Irrigated High Value Perennial Ryegrass (e.g. dairies)
Land use potential for Irrigated High Value Perennial Ryegrass (e.g. dairies): based on soil and landscape attributes only. The relative potential to sustain particular crops is... -
Land Use Potential for Irrigated Summer Fodder (maize, millet and sorghum)
Land use potential for Irrigated Summer Fodder (maize, millet and sorghum): based on soil and landscape attributes only. The relative potential to sustain particular crops is... -
Land Use Potential for Mealy Saltbush (Rhagodia parabolica)
Land use potential for Mealy Saltbush (Rhagodia parabolica): based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from... -
Biophysical Land Zones of Kangaroo Island (soil landscapes)
Land Zones represent the third level grouping of Soil Landscape Map Units within a traditional hierarchy of soil and land mapping. Land zone mapping is only complete for... -
Land Use Potential for Olives
Land use potential for Olives: based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from expert assessment of plant... -
Soil Sodium Toxicity (proportion of land affected)
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... -
Land Use Potential for Durum Wheat
Land use potential for Durum Wheat: based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from expert assessment of plant... -
Soil Mass Movement (landslip)
Mass movement (landslip) occurs on sloping ground where large slabs of the ground surface slide downhill. Mapping shows the extent of, or potential for, landslip, while detailed... -
Physical Condition of Surface Soil
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... -
Surface Soil Acidity (ASRIS)
Soils are classified according to the pH of the surface layer, according to the lower pH values recorded among similar soils, i.e. it is assumed that each soil class has a... -
Soil Alkalinity
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... -
Inherent Soil Fertility
Inherent fertility is a relative indicator of the soil's capacity to retain and release nutrients for uptake by plants, and is associated with clay and organic matter content.... -
Land Use Potential for Canola
Land use potential for Canola: based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from expert assessment of plant... -
Scalding (soils)
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... -
Depth to Hard Rock (soils)
Hard rock is basement rock or bedrock that is too hard to dig with hand tools (and does not include hardpans). Mapping shows the average estimated depth to hard rock, while... -
Soil Sodium Toxicity (depth to toxic layer)
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... -
Soil Wind Erosion Potential
Wind erosion potential, based on Soil Landscape Map Units of Southern South Australia, describes the susceptibility of land to erosion by wind, which is particularly an issue on... -
Soil Surface Carbonate
Surface carbonate often occurs as finely divided particles which reduce nutrient availability to plants and retard the degradation of some herbicides. Mapping shows the...
