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... -
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... -
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... -
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 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... -
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... -
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 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 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... -
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... -
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... -
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 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... -
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... -
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... -
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... -
Structure of Subsoil (degree of limitation)
Structure of subsoil provides an indication of impediments to root, and hence plant, growth due to poorly structured subsoils. Mapping shows the most limiting subsoil structure... -
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.... -
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...
