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... -
Depth to Watertable (soils)
Depth to watertable mapping highlights land where watertables may be sufficiently shallow on a seasonal basis to affect plant growth. It is intended to describe soil conditions... -
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 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 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... -
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... -
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... -
Soil Boron Toxicity (proportion of land affected)
Boron is an essential trace element occurring naturally in soil, but is toxic to many agricultural plants at high concentrations. High boron levels are often associated with... -
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... -
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 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... -
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... -
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... -
Subsoil Acidity (ASRIS)
Soils are classified according to the pH of the subsoil layer. Subsoil is defined as the depth range 30-80 cm. Rankings are made according to pH measurements and extrapolation... -
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... -
Land Use Potential for Wheat
Land use potential for Wheat: 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 Triticale
Land use potential for Triticale: based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from expert assessment of plant... -
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...
