Australian Soil Available Phosphorus Maps at 90-Meter Resolution

Version 1 of the Soil and Landscape Grid of Australia's Available Phosphorus product provides modelled estimates of soil phosphorus across Australia. The dataset includes 18 raster maps at six depth intervals from 0-200 cm, with a spatial resolution of 3 arc seconds (~90 meters). Data was produced by the Terrestrial Ecosystem Research Network and aligns with GlobalSoilMap specifications.

Use Cases

• Modeling agricultural fertilizer requirements based on soil phosphorus availability.
• Assessing environmental nutrient runoff risks based on soil phosphorus concentration maps.
• Conducting spatial analysis of soil health across different Australian regions and depths.
• Integrating soil attribute data with other geospatial layers for land-use planning.

Strengths

• High spatial resolution of approximately 90 meters per pixel.
• Includes data for six standard soil depths from 0-5 cm to 100-200 cm.
• Provides 18 gridded maps per attribute, including confidence limits.
• Temporal coverage spans approximately 50 years from 1970 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.
