Salinization

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. It can also come about through artificial processes . In the early stages, salinity affects the metabolism of soil organisms and reduces soil productivity, but in advanced stages it destroys all vegetation and other . How can it be measured or.

When soils are salty, the soil has greater concentrations of . Crops vary in their reaction to soil salinity. Salinization is an accumulation of salts in the soil and on the surface of the soil. Due to reduced water up-take in . Any process that affects . A soil may be rich in salts because the parent rock from which it was formed contains salts.

Sea water is another source of salts in low-lying areas along the coast. A very common source of salts in irrigated soils is the irrigation water itself.

Most irrigation waters contain some salts. After irrigation, the water . Once salinization occurs it has serious consequences such as the occurrence of . Salt-affected soils occur in more than 1countries of the world with a variety of extents, nature, and properties. Additional salts may be introduced through the application of fertilizers.

Through irrigation, some of these salts are carried away in agricultural wastewater, but over time salts build up in the soil, if not removed. Too high a concentration of salts in soil .

SOIL SALINIZATION AND LAND DESERTIFICATION.

Facultad dc Agronornia Univcrsidad Central de Venezuela Maracay, Venezuela. The sahinizatioii, or development of salt affected soils (saline and sodic),is a degra- dation process usually leading to desertification of lands.

Secondary salinization of intensively irrigated lands is an increasingly alarming redesertification process experienced in many irrigated regions of the developed countries. A study of soil salinization was conducted by Yulia Golovleva, Junior Researcher at the Eurasian Center for Food Security (ECFS). The study was carried out on the basis of the literature review under the framework of cooperation between ECFS, the Food and Agricultural Organization of the United Nations .
