The saline content of the land is called soil salinity.[1]​.

Soils affected by high levels of salinity are the product of the accumulation of salts, which are generally lower on the ground surface. Salts can be transported to the ground surface by capillary action from a salt-containing water table and then accumulate through evaporation. They can also be concentrated as a result of human activities, for example the use of potassium as fertilizer, which can form sylvite, a salt that occurs naturally in nature. As soil salinity increases, salt can cause soil and vegetation degradation.

Salinization is a process that occurs due to:.

• - high levels of salt in soils.

• - landscape features that allow salts to move. (shift of the water table).

• - climatic changes that favor the accumulation of salt.

• - human activities such as land clearing, activities related to aquaculture and throwing salt on roads in winter.[2]​.

• - Alkaline soil.

• - Atriplex (salt plant).

• - Soil acidification.

• - Control of soil salinity.

• - Water well.

• - Soil structure.

• - Soil texture.
