Australian Total Soil Phosphorus Maps at 90-Meter Resolution

Version 2 of the Australian Total Soil Phosphorus product from the Soil and Landscape Grid of Australia. It provides modelled estimates of total phosphorus distribution across Australia at six standard soil depths, with a spatial resolution of 3 arc seconds (~90 meters). The data consists of 24 gridded maps and is produced by the Terrestrial Ecosystem Research Network.

Use Cases

• Modeling agricultural nutrient requirements based on spatial phosphorus distribution.
• Assessing environmental soil health and nutrient runoff risk based on depth-specific phosphorus estimates.
• Integrating soil data into broader ecological models based on GlobalSoilMap.net standard specifications.
• Evaluating model reliability for land management decisions based on provided extrapolation risk measures.

Strengths

• Provides data for six standard soil depths (0-5cm to 100-200cm), enabling vertical profile analysis.
• High spatial resolution of approximately 90 meters per pixel, offering detailed national coverage.
• Includes 24 gridded maps per attribute, providing estimates and confidence limits for each depth layer.
• Adheres to the international GlobalSoilMap specifications, facilitating cross-study comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is modelled, not direct measurement, which may introduce estimation errors.
• Row count is unknown, which may limit suitability assessment for some analytical methods.
