Full description

This is Version 1 of the Australian Soil Inorganic Carbon products of the Soil and Landscape Grid of Australia.

The creation of this dataset (national estimates of presence and absence, depth to, concentration, and stocks of soil inorganic carbon) was performed by Ng et al. (2025) and published in Geoderma that was tiled: Mapping the distribution and magnitude of soil inorganic and organic carbon stocks across Australia. The work is available at: https://doi.org/10.1016/j.geoderma.2025.117239.

Soil Inorganic Carbon content are a set of six digital soil attribute maps, and their upper and lower confidence limits, representing the soil attribute at six depths: 0-5cm, 5-15cm, 15-30cm, 30-60cm, 60-100cm and 100-200cm.

Classification maps of presence and absence of carbonates are a set of six digital soil attribute maps, representing the soil attribute at six depths: 0-5cm, 5-15cm, 15-30cm, 30-60cm, 60-100cm and 100-200cm.

There is a single classification map showing depth to carbonates.
