salinesoil
Saline soil is a soil in which soluble salts accumulate in the root zone at levels sufficient to impair plant growth. The condition is typically identified by a high electrical conductivity of soil water extract (ECe). In many soil- and crop-science classifications, saline soils have ECe above 4 dS/m (at 25°C). The pH is usually neutral to alkaline, and the exchangeable sodium percentage is low, distinguishing them from sodic soils.
Saline soils form where evaporation concentrates salts and drainage is insufficient. Natural factors include arid and
Common salts include chlorides, sulfates, and carbonates of sodium, calcium, and magnesium. Because salts draw water
Management aims to reduce salinity in the root zone by leaching salts below the root zone, improving
Saline soils are part of a broader salt-affected soil category that also includes sodic soils (high exchangeable
