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-... -
Soil Water Repellence
Department for Environment and Water
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... -
Flooding Susceptibility (soils)
Department for Environment and Water
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 Erosion Max Potential - Wind or Water
Department for Environment and Water
Provides a numeric rating in each raster cell of the potential for erosion by wind or water in the event that vegetation or other ground cover has been removed (e.g. by fire,... -
Soil Aluminium Toxicity
Department for Environment and Water
Aluminium toxicity in plants can occur even at low concentrations. While present in most soils, the availability of aluminium to plants is highly pH dependent. Mapping shows the... -
Soil Rootzone Depth Potential CC - Hardy horticultural crops (e.g. grapes, olives)
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 Rootzone Depth Potential CE - Above ground annual crops (e.g. brassicas)
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 Salinity - Watertable induced
Department for Environment and Water
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... -
Soil Sodium Toxicity (proportion of land affected)
Department for Environment and Water
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 Mass Movement (landslip)
Department for Environment and Water
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
Department for Environment and Water
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)
Department for Environment and Water
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
Department for Environment and Water
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
Department for Environment and Water
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.... -
Scalding (soils)
Department for Environment and Water
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...
