The saltiness of natural water. The salin- ity of normal seawater is 35 parts salt per 1000 parts water.

A saline solution is a liquid impregnated with, or containing salt(s). Salinity of saturated soil extracts is determined by its electrical conductivity (EC) , expressed as decisimens per meter (dS/m).
Soils containing large quantities of soluble salts and exchangeable sodium that interfere with the growth of most crop plants are known as saline sodic soil. Saline soil is a soil, the saturation water extract of which has an electrical conductivity of more than 4 dS/meter and an exchangeable sodium concentration less than 15 % (or sodium adsorption ratio less than 13).
Salinity and sodicity of soils are two unfavorable conditions for plant growth. Correct identification of the problem is necessary for its correct reclamation. Saline soil is a non-sodic soil containing many soluble salts (that may not be tolerated by plants) and having an EC < 4 dS/m.
Dominant ions under saline conditions are calcium (Ca⁺⁺), magnesium (Mg⁺⁺), chloride (Cl ^-), bicarbonate (HCO;) and carbonate (CO3^2-). A high salt concentration in soils increases the water-holding capacity of the soil particles. This makes it increasingly difficult for plants to use the water. Another feature of salinity is the toxicity of one or more ions of the salt. Plants suffering from salt damage may show leaf scorching, indicating toxicity of sodium or chloride; leaves may become yellow prematurely, wither and drop. Often, such plants look dull and dark and grow stunted.
