Australian Soil pH Maps at Six Depths, 90m Resolution

Australia-wide modelled estimates of soil pH (1:5 soil water solution) across six standard depths from 0-5 cm to 100-200 cm. The Soil and Landscape Grid of Australia produced 18 raster maps at a 3 arc-second resolution (~90m pixels), with data coverage from approximately 1950 to 2021. This version 1 product follows GlobalSoilMap specifications and is provided by the Terrestrial Ecosystem Research Network.

Use Cases

• Model agricultural suitability and crop yield based on soil pH levels.
• Analyze soil acidity trends across different depths and regions of Australia.
• Integrate soil property data with other environmental layers for ecosystem modeling.
• Assess the impact of historical land use on soil chemistry over time.

Strengths

• Provides data for six standardized soil depths consistent with GlobalSoilMap specifications.
• High spatial resolution of approximately 90 meters per pixel.
• Includes upper and lower confidence limits for each modelled pH estimate.
• Covers a long temporal period from approximately 1950 to 2021.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
