Land Types of Southern South Australia (soil landscapes)
Land Types define the broad soil grouping and dominant geologic and topographic setting of Soil Landscape Map Units. There are 29 Land Types within 14 geomorphic groups which... -
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... -
Biophysical Subregions of Southern South Australia (soil landscapes)
Biophysical Subregions correspond to the second largest grouping of Soil Landscape Map Units within the SA soil and land mapping hierarchy. Biophysical Subregions are delineated... -
Land Systems of Southern South Australia (soil landscapes)
Land Systems (based upon groupings of Soil Landscape Map Units) are broad and readily recognisable landscape areas defined by particular and distinctive patterns of land use,... -
Soil Landscape Map Units of Southern SA
Soil Landscape Map Units have recognizable topographic features formed on a particular geological material and containing a limited and defined range of soils. They therefore... -
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... -
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... -
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... -
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... -
Soil Exposure
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 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,... -
Soil Water Erosion Potential
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... -
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... -
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... -
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 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... -
Soil Waterlogging Susceptibility
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 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... -
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....
