Physical Condition of Surface Soil
Department for Environment and Water
Physical condition of surface soil mapping highlights areas where plant growth may be impeded due to poor surface soil structure, predominantly due to a condition known as hard... -
Surface Soil Acidity (ASRIS)
Department for Environment and Water
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... -
Soil Alkalinity
Department for Environment and Water
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... -
Inherent Soil Fertility
Department for Environment and Water
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.... -
Land Use Potential for Canola
Department for Environment and Water
Land use potential for Canola: based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from expert assessment of plant... -
Scalding (soils)
Department for Environment and Water
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... -
Depth to Hard Rock (soils)
Department for Environment and Water
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 Sodium Toxicity (depth to toxic layer)
Department for Environment and Water
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 Wind Erosion Potential
Department for Environment and Water
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 Surface Carbonate
Department for Environment and Water
Surface carbonate often occurs as finely divided particles which reduce nutrient availability to plants and retard the degradation of some herbicides. Mapping shows the... -
Surface Soil Texture
Department for Environment and Water
Surface texture (which refers to approximate clay content) influences many important soil qualities such as waterholding capacity, fertility and erodibility. Mapping shows the... -
Soil Boron Toxicity (proportion of land affected)
Department for Environment and Water
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... -
Land Use Potential for Irrigated Pasture (best rating)
Department for Environment and Water
Land use potential for Irrigated Pasture (best rating of Irrigated: Lucerne, High Value Perennial Ryegrass, Perennial Ryegrass; White Clover): based on soil and landscape... -
Soil Groups
Department for Environment and Water
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 Deep Drainage Potential
Department for Environment and Water
Deep drainage refers to the capacity of the deep subsoil and the material immediately below the soil profile to allow excess water to move downwards into deep sediments or... -
Land Use Potential for Tall Scurf-pea (Cullen australasicum)
Department for Environment and Water
Land use potential for Tall Scurf-pea (Cullen australasicum): based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from... -
Soil Acidity
Department for Environment and Water
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,... -
Land Use Potential for Irrigated Lucerne
Department for Environment and Water
Land use potential for Irrigated Lucerne: based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from expert assessment of... -
Soil Rootzone Depth Potential CB - Intermediate horticultural crops (e.g....
Department for Environment and Water
Potential rootzone depth for irrigated horticultural crops is affected by a range of soil parameters (e.g. soil physical condition, hard rock or hardpan, soluble salts, boron... -
Structure of Subsoil (degree of limitation)
Department for Environment and Water
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...
