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 …
WebElevation, subsidence (e.g., the sinking of land due to natural and human-caused factors), and drainage all influence the vulnerability of lands to saltwater intrusion and salinization. Coastal forests and farms are particularly vulnerable to salinization due to their low elevation, proximity to oceans, and high rates of soil subsidence.
