From data.gov.au 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... -
From data.gov.au Soil Available Waterholding Capacity
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... -
From data.gov.au 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... -
From data.gov.au Soil Salinity - Non-watertable
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-... -
From data.gov.au 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... -
From data.gov.au 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... -
From data.gov.au Soil Erosion Max Potential - Wind or 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,... -
From data.gov.au Soil Aluminium Toxicity
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... -
From data.gov.au Soil Rootzone Depth Potential CC - Hardy horticultural crops (e.g. grapes, olives)
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... -
From data.gov.au 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... -
From data.gov.au 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... -
From data.gov.au 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... -
From data.gov.au 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... -
From data.gov.au 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... -
From data.gov.au 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... -
From data.gov.au 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... -
From data.gov.au 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.... -
From data.gov.au 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... -
From data.gov.au 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... -
From data.gov.au 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...
