Australian Soil Clay Content Maps at Six Depths, 90m Resolution

Version 2 of the Australian Soil Clay Content product from the Soil and Landscape Grid of Australia. It provides 18 raster maps estimating clay mass fraction at six standard depths from 0-5cm to 100-200cm, with a spatial resolution of 3 arc seconds (~90 meters). The data is produced by the Terrestrial Ecosystem Research Network and adheres to GlobalSoilMap specifications.

Use Cases

• Modeling soil water retention and erosion risk based on clay content estimates.
• Assessing agricultural land suitability and crop yield potential across Australia.
• Integrating soil property data into broader environmental and climate models.
• Validating and updating regional soil survey maps with continuous national coverage.

Strengths

• Provides data for six standardized depth intervals consistent with GlobalSoilMap specifications.
• Offers high spatial resolution of 3 arc seconds, approximately 90 by 90 meter pixels.
• Includes upper and lower confidence limits for each of the 18 attribute maps.
• Covers a long temporal period, approximately from 1950 to 2021.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic or methodological bias inherent to the modeling approach.
