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... -
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... -
Land Use Potential for Lupins
Land use potential for Lupins: based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from expert assessment of plant... -
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... -
Depth to Hardpan (soils)
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... -
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 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... -
Soil Recharge Potential
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... -
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... -
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... -
Land Use Potential for Potatoes
Land use potential for Potatoes: 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 Grape Vines
Land use potential for Grape Vines: 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 Dryland Lucerne
Land use potential for Dryland Lucerne: based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from expert assessment of... -
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 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... -
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... -
Surface Rockiness (soils)
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 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 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,...
