Excess salts in the root zone of soils in the arid and semi-arid climates are a worldwide phenomenon. However, the most serious salinity and sodicity problems are being faced in the irrigated arid and semi-arid regions of the world and it is in these regions that irrigation is essential to increase agricultural production to satisfy food requirements. Soil salinity is also a serious problem in areas where groundwater of high salt content is used for irrigation (Zewdu et al., 2015).
