- •
Comparison of ANOCOVA and remote sensing (RS) approaches for mapping soil salinity.
- •
Cross validation confirmed robustness of ANOCOVA and RS salinity assessment.
- •
RS salinity assessment approach was most cost effective for landscape to regional scales.
- •
ANOCOVA approach proved more appropriate for multiple-field to landscape scales.
- •
The study provides guidelines, strengths, and weaknesses for ANOCOVA and RS approaches.
