Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. [1] Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean.
The Dau Tieng – Phuoc Hoa irrigation system, under the management of the Southern Irrigation Exploitation One Member Limited Liability Company, serves to provide water, control floods, repel salinity, and improve the environment for the downstream areas of the Saigon and Vam Co Dong river basins.

Soil salinity control refers to controlling the process and progress of soil salinity to prevent soil degradation by salination and reclamation of already salty (saline) soils. Soil reclamation is also known as soil improvement, rehabilitation, remediation , recuperation, or amelioration.
The salt level is often taken as the soil salinity or the salinity of the irrigation water. Salt tolerance is of importance in irrigated lands in (semi)arid regions where the soil salinity problem can be extensive as a result of the salinization occurring here. It concerns hundreds of millions of hectares. [2]
Annual mean sea surface salinity for the World Ocean. Data from the World Ocean Atlas 2009. [1] International Association for the Physical Sciences of the Oceans (IAPSO) standard seawater. Salinity (/ s ə ˈ l ɪ n ɪ t i /) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is ...
Freshwater salinization-- increases in water salinity due to water pollution Topics referred to by the same term This disambiguation page lists articles associated with the title Salinization .
The soil salinity on the x-axis is represented by electric conductivity (ECe). In this example the crop has a salt tolerance (threshold) of ECe = Pb = 7 dS/m beyond which the yield diminishes. The Maas–Hoffman model is a mathematical tool to characterize the relation between crop production and soil salinity.
This is a list of bodies of water by salinity that is limited to natural bodies of water that have a stable salinity above 0.05%, at or below which water is considered fresh. Water salinity often varies by location and season, particularly with hypersaline lakes in arid areas, so the salinity figures in the table below should be interpreted as ...
