Besides the extensive use of saline soils reclaimed for rainfed crops, a number of saline plains, in particular those of the Mejerda Valley, have intensively been exploited using drainage and irrigation techniques. In these drained plains, the hydrological characteristics of the groundwater table and the physicochemical properties of the soil material, originally saline and sodic, have been modified. A few cases of saline soil reclamation are presented in this paper.
