Abstract

Salinity in arid and semi-arid lands is becoming an ever increasing problem with 222 750 ha of irrigated lands going out of production annually. Salt accumulation, as well as producing toxic concentrations that stress plant growth also reduces water availability to the plant by increasing the osmotic potential of the rhizosphere. In addition, high sodium ions in the soil can negatively affect the physical soil characteristics, for example, sodic soils,which have a high concentration of exchangeable sodium but a low concentration of total salts, can seriously affect soil structure and become impermeable, thereby further reducing water availability (Briggs 1996).
