WebSep 26, 2024 · Introduction. Soil salinization refers to the process of salt accumulation in terrestrial landscapes. It occurs naturally where evaporation is high relative to precipitation (there is a seasonal water deficit) and leaching is insufficient to move salts out of the soil profile (Duchaufour, 1982; Schofield & Kirkby, 2003), often in landscapes that do not drain … WebAs salty water from areas affected by dryland, irrigation and urban salinity flows into creeks and rivers, the concentration (electrical conductivity or EC) and volume (load) of salt increases.
