Subsoil Acidity (ASRIS)
Department for Environment and Water
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... -
Soil Gully Erosion
Department for Environment and Water
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... -
Surface Rockiness (soils)
Department for Environment and Water
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... -
Soil Rootzone Depth Potential CA - Sensitive horticultural crops (e.g....
Department for Environment and Water
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 Recharge Potential
Department for Environment and Water
Recharge potential mapping shows the proportion of land with high to moderate potential for water to access groundwater systems via the soil. Detailed map unit proportion data... -
Subsoil Carbonate
Department for Environment and Water
Fine carbonates in soil reduce nutrient availability to plants, while hard carbonate (e.g. rubble or hard pans) can restrict root growth and soil waterholding capacity. Mapping... -
Soil Waterlogging Susceptibility
Department for Environment and Water
Waterlogging susceptibility describes the degree and duration of impact to soils, and hence plants, arising from poor drainage. Mapping indicates the most severely waterlogged... -
Soil Rootzone Depth Potential CD - Root crops (e.g. potatoes, carrots, onions)
Department for Environment and Water
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 Exposure
Department for Environment and Water
Exposure to harsh winds and sun, as determined by local topography and prevailing winds, can impede plant growth. Mapping shows the highest degree of exposure in a map unit... -
Soil Salinity - Non-watertable (magnesia patches)
Department for Environment and Water
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... -
Depth to Hardpan (soils)
Department for Environment and Water
Hardpan is material that is too hard to dig with hand tools, that has formed in-situ within or below a soil. Mapping shows the average estimated depth to hardpan, while detailed... -
Soil Wind Erosion Potential
Department for Environment and Water
Provides a numeric rating in each raster cell of the potential for wind erosion in the event that vegetation or other ground cover has been removed. The assessment is based on... -
Soil Water Erosion Potential
Department for Environment and Water
Water erosion potential, based on Soil Landscape Map Units of Southern South Australia, describes the susceptibility of land to sheet or rill erosion due to overland flow of... -
Acid Sulfate Soil Potential
Department for Environment and Water
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... -
Current and Future Potential Soil Acidity (ASRIS)
Department for Environment and Water
Combines the assessment of soils that are currently acidic (or prone to acidification in the short term) and soils that are not currently recognised as acid prone, but could... -
Subsurface Soil Acidity (ASRIS)
Department for Environment and Water
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... -
Soils (soil type)
Department for Environment and Water
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... -
Soil Available Waterholding Capacity
Department for Environment and Water
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... -
Future Acidification Potential (ASRIS)
Department for Environment and Water
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... -
Soil Salinity - Non-watertable
Department for Environment and Water
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-...
