DescriptionMany plants are sensitive to aluminium at even small concentrations. Aluminium occurs in most soils, but its availability to plants is highly pH dependent. Although there is some evidence to suggest that aluminium availability increases in strongly alkaline soils, most aluminium toxicity is reported in strongly acidic soils. As a general rule, correction of soil acidity will alleviate aluminium toxicity symptoms. This assessment has been based on critical levels for aluminium sensitive plants such as lucerne. Four Aluminium Toxicity analysis data classes (including not applicable) have been supplied as percentage values for each Soil Landscape Map Unit to be used for the calculation of spatial data statistics. Note: the sum of all percentage values for each map unit totals 100%. Toxicity potential can vary significantly within a Soil Landscape Map Unit which is categorised INTO eight (plus not applicable) legend categories (TOX_AL) according to the proportion of high and moderate toxicity. Because aluminium toxicity is so highly pH dependent, and pH in turn is highly management dependent, the legend categories are generalised.
UsageLink 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. Aluminium Toxicity dataset can be viewed at NatureMaps (>Soils>Soil Chemistry Attributes). Spatial data downloads are available from Data SA.

Data Quality

LineageThe 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.

CompletenessComplete. The spatial data is subject to amendment as and when more data become available.
Positional AccuracyThe 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.
