Soil salinity is the salt content in the soil. Salt-affected soils are caused by excess accumulation of salts from high salinity irrigation water, the use of potassium as a fertilizer which can form a naturally occurring salt in saltwater coastal areas where atmospheric deposition naturally occurs, or salts can be transported to the soil surface by capillary transport from a salt laden water table and then accumulate due to evaporation. As soil salinity increases, salt effects can result in degradation of soils and vegetation.
