Description

DescriptionThis analysis is based on Soil Landscape Mapping of SA's agricultural districts using soil class information in the nationally-consistent ASRIS data format. Future acidification potential is a term which applies to soils which are not currently acidic (or prone to acidification in the short term), but could conceivably become acidic in future, in the absence of ameliorative management practices. 'Future' implies a time frame of 10-50 years from 2015. Soils already classified as acidic (i.e. surface pHCaCl2 < 5.5) are excluded from the calculation. Soils which have calcareous surfaces (or have pHCaCl2 > 7.5) are considered to have no future acidification potential. Remaining soils are assessed according to current surface pH, surface clay content and rainfall zone. Four Future Acidification Potential attribute (or 'analysis data') classes have been supplied (see 'H_POT_1', 'H_POT_2', etc. in the table below) as percentage (areal extent) values of each Soil Landscape Map Unit. Note: the sum of all percentage values for each map unit totals 100%. This analysis data is to be used for the creation of spatial data statistics. For map display purposes, each Soil Landscape Map Unit is assigned to one of seven (including 'not applicable') legend categories (ACID_POT).
UsageThis dataset has been derived from the Soil Landscape Map Units spatial dataset (here combined with ASRIS soil data tables) 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 data for commercial decisions. Further information: National-format soil and land attributes. The Future Acidification Potential (ASRIS) dataset can be viewed at NatureMaps (>Soils>Soil Chemistry Attributes). Spatial data downloads are available from Data.SA. A sample map can be downloaded from Enviro Data SA. Related datasets: Surface Soil Acidity, Subsurface Soil Acidity, and Subsoil Acidity.

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.
