Abstract:
Saline soils exist in arid and semi-arid climates and in regions with poor drainage. A low infiltration rate is associated with sodic soils. Whereas adsorbed Na and Ca ions affect plant growth through changes in soil physical properties, B may cause injury to plants even when present at very low concentrations in the soil solution. A successful irrigated agriculture requires permanent control of salinity, sodicity and B levels in soils and irrigation water. Reclamation of affected soils by means of improved drainage, chemical treatments and leaching of salts, can reduce natural hazards and make a stable background for intesive cropping. Such reclamation is the focus of this chapter.
