Flooding Susceptibility (soils)
Susceptibility to flooding imposes a serious limitation on land especially where infrastructure is required. Mapping shows the proportion of land susceptible to flooding, while... -
Soil Water Repellence
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... -
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... -
Future Acidification Potential (ASRIS)
Future acidification potential is a term which applies to soils which are not currently acidic (or prone to acidification in the short term), but could conceivably become acidic... -
Subsoil Acidity (ASRIS)
Soils are classified according to the pH of the subsoil layer. Subsoil is defined as the depth range 30-80 cm. Rankings are made according to pH measurements and extrapolation... -
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... -
Land Use Potential for Wheat
Land use potential for Wheat: based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from expert assessment of plant... -
Land Use Potential for Triticale
Land use potential for Triticale: based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from expert assessment of plant... -
Acid Sulfate Soil Potential
Acid sulfate soil potential mapping shows the proportion of land susceptible to the development of acid sulfate soils, while detailed proportion data are supplied for... -
Surface Soil Texture
Surface texture (which refers to approximate clay content) influences many important soil qualities such as waterholding capacity, fertility and erodibility. Mapping shows the... -
Soil Acidity
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,... -
Subsurface Soil Acidity (ASRIS)
Soils are classified according to the pH of the subsurface layer. Subsurface soil refers to the layer immediately below the surface, and typically has a depth range of 10-20... -
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... -
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... -
Physical Condition of the Soil
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.... -
Soil Groups
Fifteen soil groups have been identified across southern South Australia, which are groupings of 61 soils (soil types). Mapping shows the most common soil group, while more... -
Soils (soil type)
Sixty one soils (soil types) represent the range of soils found across South Australia’s agricultural lands. Mapping shows the most common soil within each map unit, while more... -
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 Rootzone Depth Potential CE - Above ground annual crops (e.g. brassicas)
Potential rootzone depth for irrigated horticultural crops is affected by a range of soil parameters (e.g. soil physical condition, hard rock or hardpan, soluble salts, boron... -
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...
