- •
Digital soil mapping was used to map salinity hazard across state borders.
- •
EM induction and elevation data were combined to predict clay and salt content.
- •
Deep drainage was modelled using EM38 data by SaLF model.
- •
Expert knowledge was used to determine the threshold for salinity hazard factors.
- •
Indicator kriging was used to map the salinity hazard and account for uncertainty.
