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... -
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... -
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 Salinity - Non-watertable (magnesia patches)
Non-watertable salinity (or dry saline land) is where soil contains elevated levels of soluble salts that are not associated with a watertable. Magnesia patches occur where high... -
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... -
Physical Condition of the Soil
Physical condition of soil provides an integrated view of various physical impediments to plant growth associated with surface soils, subsoils and other limitations (e.g.... -
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... -
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 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 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 Rootzone Depth Potential CC - Hardy horticultural crops (e.g. grapes, ol...
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 CD - Root crops (e.g. potatoes, carrots, onions)
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 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... -
Soil Rootzone Depth Potential CB - Intermediate horticultural crops (e.g. sto...
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...
