Soil salinity is the salt content in the soil. Salt affected soils are caused by excess accumulation of salts, typically most pronounced at the soil surface. Salts can be transported to the soil surf...

What is salinization? Salinization is the process by which water-soluble salts accumulate in the soil. Salinization is a resource concern because excess salts hinder the growth of crops by limiting their ability to take up water.

Salinization occurs in warm and dry locations where soluble salts precipitate from water and accumulate in the soil. Saline soils are common in desert and steppe climate. Salt may also accumulate in soils from sea spray.

Salinization occurs frequently from overirrigated soil when evaporation of water at the surface draws salts from underground rocks and soils, causing salts to crystallize and interfere with root growth.

Salinization refers to a build up of salts in soil, eventually to toxic levels for plants. (3,000 - 6,000 ppm salt results in trouble for most cultivated plants.) Salt in soils decreases the osmotic potential of the soil so that plants can't take up water from it.

Salt-affected irrigated land represents about 10% of salinization due to human actions (corresponding to 20% of salt-affected land). ... Today, 10% to 15% of irrigated areas (45 Mha) suffer, to various degrees, from salinization problems. From 0.5% to 1% of irrigated areas are lost each year. Nearly half of all irrigated...

Salinization of Soil and Wate ... The main impacts of irrigated agriculture in the Southwest are due to the building of dams and the diversion of water, the waterlogging of soils, the overdraft of groundwater resources, and the salinization of soil and water.

Desertification is the process which turns productive into non- productive desert as a result of poor land-management. Desertification occurs mainly in semi-arid areas (average ... * Incorrect irrigation practices in arid areas can cause salinization, (the build up of salts in the soil) which can prevent plant growth.

Soil Damage and Erosio ... Return to Rural Land Degradation ... 1. removal of the vegetation cover. This means that no further humus is added to nourish the soil and there are no roots to bind the soil together. If the surface is exposed to wind and rain, the soil will be carried away leaving deep gullies or bare rock e.g.
