Stochastic Approaches for Space–Time Modeling and Interpolation of Soil Salinity

The concentration of soluble salts in the soil is one of the most important factors of land degradation that affects land utilization and reclamation. The effective control of soil salinity and waterlogging requires, among others, knowledge of the magnitude, extent and distribution of root zone salinity (inventory), knowledge of the changes and trends in soil salinity over time (monitoring), and the ability to determine the impact of management changes upon saline conditions (Rhoades et al., 1999).
