This report presents digital soil maps over NSW for a range of key soil properties, derived using quantitative modelling techniques. The properties covered include soil organic carbon (SOC), pH, cation exchange capacity, sum-of-bases, total phosphorous, electrical conductivity (EC), exchangeable sodium percent (ESP), clay, sand and silt. The maps are at 100 metre spatial resolution and cover six soil depth intervals down to 2 metres, consistent with major Australian and international systems. Validation results for the maps indicate at least moderate performance and effectiveness.
The maps provide a useful first approximation of these important soil properties, and complement existing conventional and other digital soil maps available over NSW. They can assist in sustainable management of our soil resources and provide valuable input into other natural resource and environmental modelling systems throughout the State.
