Vulnerable Soils: Salinity Hazard
Soil salinity hazard was digitally mapped as part of the DPIPWE Water for Profit Program to enhance identification of Enterprise Suitability by effectively incorporating a sustainability measure of vulnerable soils. The mapping shows areas where a salinity hazard might exist if sufficient management is not applied, which could lead to soil resource degradation. Assigned classes are; Low, Moderate and High as classified ratings of a salinity hazard index. The index was generated by combining Digital Soil Mapping (DSM) inputs of the soil properties of Electrical Conductivity (EC) and Clay % for standard depths, with ratings developed by the DPIPWE Land Degradation and Salinity Risk assessments. The mapping covers the entire state of Tasmania at 30m resolution.
