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... -
Land Use Potential for Potatoes
Land use potential for Potatoes: 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 Grape Vines
Land use potential for Grape Vines: 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 Dryland Lucerne
Land use potential for Dryland Lucerne: based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from expert assessment of... -
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... -
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... -
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 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... -
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... -
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...
