the accumulation of salts in the soil to a level that causes degradation of the soil.
The accumulation of soluble salts in soil or water so that they become unfit for their normal uses, such as growing plants or providing drinking water. The main salt is sodium chloride (common table salt) but potassium chloride and magnesium sulfate can also accumulate.
the process by which land becomes salt affected
The process whereby soluble salts accumulate within the soil.
A net increase of the salt content of the soil leading to a productivity decline. Salinity problems are due either to intrusion of seawater or to inland salinisation, mainly caused by improper irrigation methods.
