Description

DescriptionA series of spatial datasets depicting the potential of land for a range of agricultural uses. Distinct landscape features are classified with respect to a range of Soil and Land Attributes that affect agricultural and horticultural land use. By matching the values of these attributes, with expert assessed requirements of specific crops, the relative potential (CLASS1: high potential - CLASS5: low potential) to sustain particular crops is predicted. The most significant limiting attribute largely dictates this prediction of productive potential. Soil Landscape Map Units are typically heterogeneous (ie contain multiple landscape features) and are categorised for map display purposes, the overall properties of the map unit. Models are based on Soil and Land Attributes only - no account has been taken of water quality or availability, climatic factors or existing land use. Models have NOT been ground-truthed and should be considered preliminary. Land Use Potential models have been developed for the following crop types: ALMONDS; APPLES; BARLEY; BRASSICAS; CANOLA; CARROTS; CHERRIES; CHESTNUTS; CHICKPEAS; CITRUS; CULLEN; EREMOPHILIA GLABRA; FABA BEANS; FIELD PEAS; GRAPE VINES; GRAPE VINES (mechanically harvested); HAZELNUTS; LAVENDER; LENTILS; DRYLAND LUCERNE; DRYLAND LUCERNE (acid soil tolerant); IRRIGATED LUCERNE; LUPINS; OATS; OLIVES; ONIONS; DRYLAND PASTURE (best rating); IRRIGATED PASTURE (best rating); PEARS; DRYLAND PHALARIS; POTATOES; PYRETHRUM; RHAGODIA PARABOLICA; RHAGODIA PREISSII; DRYLAND PERENNIAL RYEGRASS; IRRIGATED PERENNIAL RYEGRASS; IRRIGATED PERENNIAL RYEGRASS (high value, eg dairies); SALTBUSH; DRYLAND STRAWBERRY CLOVER; DRYLAND SUBTERRANEAN CLOVER; IRRIGATED SUMMER FODDER (maize, millet, sorghum); TRITICALE; WHEAT; DURUM WHEAT; IRRIGATED WHITE CLOVER.
UsageTo determine the potential of our land and soils to support particular uses; Policy development; Industry development; Planning. Map legend categories (*CROP*_9) are for map display and are NOT to be used for calculating spatial data statistics (i.e. areas of each Land Use Potential class). This is because Soil Landscape Map Units are typically heterogeneous and contain land of different Land Use Potential classes and a significant part of the Analysis Data described for a map unit may be lost. Analysis Data classes (i.e. CLASS1, CLASS2, etc.) are to be used to generate more accurate statistics. For information regarding assessment and mapping methodology please see Land Use Potential Description Documentation. Spatial datasets can be downloaded from Data.SA. Land Use Potential data is viewable at: NatureMaps (>Soils>Land Use Potential) and AgInsight. Further information: Assessing land use potential.

Data Quality

LineageEach model is based on an interpretation of the comprehensive information contained in the State's Soil and Landscape Mapping Database which spans the agricultural areas of South Australia (southern SA). That mapping program has undergone limited field and laboratory verification. Classifications are subject to change as the data and methodology are enhanced. Maps are intended to provide a regional overview and should not be used to draw conclusions about conditions at specific locations. Land Use Potential data is based on Soil Landscape Map Units. To avoid inconsistencies and confusion, any updates to the Land use potential 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 should be acknowledged and any changes to original data should be indicated.
CompletenessComplete
Positional AccuracyThe accuracy is to the scale of mapping, and is to be used at regional level. It is not considered accurate at property level.

TableNameField AliasData TypeDescription
LANDSCAPE.LandUsePotentialLANSLU CharacterSoil Landscape Map Unit. Each map unit has recognizable topographic features formed on a particular geological material and containing a limited and defined range of soils. They therefore have similar land and soil characteristics and land use potential.
LANDSCAPE.LandUsePotential*CROP*_9 CharacterLand Use Potential legend categories for specific *CROP* (see list of crop models above). Legend categories show the percentage of moderate to high potential land and the most common potential class. LAND USE POTENTIAL 9-CLASS LEGEND CATEGORIES (eg WHEAT_9): Aa: >60% moderate to high / high; Ab: >60% moderate to high / moderately high; Ac: >60% moderate to high / moderate to high; Ad: >60% moderate to high / moderate; B: 30-60% moderate to high / low to high; C: 10-30% moderate to high / moderately low to low; D: 1-10% moderate to high / moderately low to low; Ea: <1% moderate to high / moderately low; Eb: <1% moderate to high / low; X: Not applicable (urban, lakes, reservoirs, etc).
LANDSCAPE.LandUsePotentialCLASS1 IntegerCLASS 1: Proportion of land which has high productive potential and requires no more than standard management practices to sustain productivity
LANDSCAPE.LandUsePotentialCLASS2 IntegerCLASS 2: Proportion of land which has moderately high productive potential and / or requires specific, but widely accepted and used, management practices to sustain productivity
LANDSCAPE.LandUsePotentialCLASS3 IntegerCLASS 3: Proportion of land which has moderate productive potential and / or requires specialized management practices to sustain productivity
LANDSCAPE.LandUsePotentialCLASS4 IntegerCLASS 4: Proportion of land which has moderately low (marginal) productive potential and / or requires very highly specialized management skills to sustain productivity
LANDSCAPE.LandUsePotentialCLASS5 IntegerCLASS 5: Proportion of land which has low potential and / or permanent limitations which effectively preclude its use
LANDSCAPE.LandUsePotentialCLASSX IntegerCLASS X: Proportion of land which is not applicable
