Soil salination is the accumulation of free salts to such an extent that it leads to
degradation of soils and vegetation.Salination is a natural process that results from:high levels of salt in the soils.landscape features that allow salts to become mobile (movement of water table)climatic trends that favor accumulation
Salt is a natural element of soils and water. The ions responsible for salination are: Na+, K+, Ca2+, Mg2+ and Cl-. As the Na+ (sodium) predominates, a salinised soil is also a sodic soil.
