Description Category Soils Theme Soil Landscapes Keywords and Qualifiers SOIL Dataset Type Spatial Description Scalding refers to land where the surface soil has been eroded, exposing sub-surface material which is physically and/or chemically hostile to plant growth. As a consequence, the bare surface is susceptible to further erosion, and may shed sufficient water to cause off-site erosion. Scalding is primarily a condition affecting land in low rainfall environments. This assessment does not include bare land associated with saline groundwater. Magnesia patches, are bare areas caused by high near surface concentrations of soluble salts (not linked to a watertable) which are considered separately. Similarly, bare ground caused by near surface saline groundwater tables, is not classified as scalded. Three Scalding (including not applicable) analysis data classes have been supplied, as percentage values of Soil Landscape Map Units to be used for the calculation of spatial data statistics. Note: the sum of all percentage values for each map unit totals 100%. Each Soil Landscape Map Unit is categorised INTO five (plus not applicable) legend categories (EROS_SCALD) according to the proportion of its area affected by scalding. Dataset Use Link to Soil Attribute Descriptions. This dataset has been derived from the Soil Landscape Map Units spatial dataset to be used for map creation or the calculation of spatial data statistics. Used to supply Government, community groups, industry and the general public with up to date regional, subregional and catchment level land and soil attribute information for southern South Australia. The aim is to produce maps, statistics and reports displaying and describing: Land and soil attributes within southern South AustraliaSELECT 1 FROM DUAL; Land surface features affecting land use, land management and productivitySELECT 1 FROM DUAL; Limitations / suitability of land and soil for a range of agricultural and other uses. Independent professional advice should be sought before using this in commercial decisions. Further information: soil and land attributes. Scalding dataset can be viewed on NatureMaps (>Soils>Soil Erosion Attributes). Spatial data downloads are available from Data SA.

Data Quality Lineage The dataset is based on an interpretation of 1:40,000 stereo colour aerial photography and limited field inspection of landscapes and soils by soil scientists. Soil Landscape Map Unit boundaries were determined after an integration of field observations and recordingsSELECT 1 FROM DUAL; laboratory analysesSELECT 1 FROM DUAL; stereoscopic examination of aerial photographsSELECT 1 FROM DUAL; understanding of regional landscape processes and stratigraphySELECT 1 FROM DUAL; existing soil and geological mapping data. To avoid inconsistencies and confusion, any updates to the Soil and Land Attribute mapping are to be managed by DEWNR Soil and Land Program. This data has been released under a Creative Commons licence. Where products are derived from this data, DEWNR are to be acknowledged, and any changes to the original data should be indicated. Completeness Complete. The spatial data is subject to amendment as and when more data become available. Positional Accuracy The accuracy is to the scale of mapping (50 metres at 1:50,000 and 300 metres at 1:100,000 mapping scale). The spatial data is to be used at the regional, subregional and catchment level, and can be used to provide property overviewsSELECT 1 FROM DUAL; however, cannot be used at the paddock level. South East, Kangaroo Island, Mount Lofty Ranges and the 'bottom' of Yorke Peninsula have been mapped at 1:50,000. Eyre Peninsula, the main part of Yorke Peninsula, Murray Mallee and Northern Agricultural Districts have been mapped at 1:100,000. Map unit boundaries should be treated as transition zones.
