Victorian Digital Soil Map: Soil Properties at Six Depth Intervals

Victoria, Australia, is covered by a soil property map at six prescribed depths from 0 to 200 cm. The dataset includes pH, electrical conductivity, clay percentage, and soil organic carbon, derived from over 6,000 sites in the Victorian Soil Information System. It was created by the Understanding Soil and Farming Systems project and is Version 1.0 of the Victorian Digital Soil Map.

Use Cases

• Modeling soil salinity impacts on crop yield based on electrical conductivity (EC) measurements.
• Assessing soil acidity for agricultural planning based on pH mapping at multiple depths.
• Estimating soil carbon sequestration potential based on soil organic carbon (SOC %) percentages.
• Analyzing soil texture and water retention characteristics based on clay percentage data.
• Creating reliability assessments for soil property predictions based on assignment qualifier attributes.

Strengths

• Maps four key soil properties (pH, EC, % clay, SOC %) across the entire state of Victoria.
• Integrates data from over 6,000 soil sites standardized to six consistent depth intervals.
• Provides both polygon (land unit) and 100m resolution grid formats for each property and depth.
• Includes reliability maps derived from assignment qualifiers for quality evaluation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is Version 1.0, and a revised version was due in 2014, suggesting potential obsolescence.
• Row count is unknown, which may limit suitability assessment for large-scale statistical modeling.
