The use of remote sensing in soil and terrain mapping — A review

V.L. Mulder, S. de Bruin, M.E. Schaepman, T.R. Mayr
2011 Geoderma  
Surface soil moisture is derived from the backscatter data and then used to compute the SWI, which gives relative values of soil water content over the rooting depth.  ...  Soil salinity In arid and semi-arid climates, precipitation is insufficient to maintain a regular percolation of rainwater through the soil, so soluble salts accumulate, with consequences for soil properties  ...
