Putting regional digital soil mapping into practice in Tropical Northern Australia

Tropical Northern Australia is a vast region dominated by extensive cattle grazing. Australia is seeking opportunities to intensify land use in this region through irrigation. We describe a digital soil mapping (DSM) approach for the Flinders and Gilbert catchments (combined area, 155,000km2) in north Queensland to supply soil property (i.e. target variable) maps for an eventual crop-specific irrigation suitability assessment.
