Soil Rootzone Depth Potential CC - Hardy horticultural crops (e.g. grapes, olives)
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... -
Soil Rootzone Depth Potential CE - Above ground annual crops (e.g. brassicas)
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... -
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... -
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 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... -
Physical Condition of Surface Soil
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... -
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... -
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.... -
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... -
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 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 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 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... -
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... -
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... -
Soil Deep Drainage Potential
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... -
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,... -
Soil Rootzone Depth Potential CB - Intermediate horticultural crops (e.g....
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)
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... -
Soil Boron Toxicity (depth to toxic layer)
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...
