  • 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...
  • 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...
  • 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,...
  • Subsoil Carbonate

    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...
  • 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...
  • 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...
  • Soil Gully Erosion

    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...
  • 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 Surface Carbonate

    Surface carbonate often occurs as finely divided particles which reduce nutrient availability to plants and retard the degradation of some herbicides. Mapping shows the...
