Soil Salinization: How To Prevent And Manage Its Effects
WebFeb 21, 2021 · Soil salinization occurs when soluble salts are retained in the earth. It happens either naturally or because of improper anthropogenic activities, particularly farming practices. Besides, some earths are initially saline due to low salt dissolution and removal. Soil salinization causes include:
Soil salinity - Wikipedia
WebSoil salinity is the salt content in the soil; the process of increasing the salt content is known as 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.

WebThis article presents an overview of soil salinization dealing with different aspects such as processes and assessment of salinization, distribution and extent of salt-affected soils, soil behavior in relation to the composition of salts, direct and indirect constraints to crop production in salinized soils, plant factors in adapting to ...
Causes of Soil Salinization, Sodification, and Alkalinization
WebSoil 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 ...
Salinization - an overview | ScienceDirect Topics
WebSalinization is the precipitation of salts in soils (Fig. 3) and is found mostly in desert soils (Aridisols). The most common salts are halite and gypsum, which can form either as clear crystals within soil cracks or as sand crystals that engulf the pre-existing soil matrix.

Soil Salinization - Environmental Science - Oxford Bibliographies
WebNov 25, 2014 · Soil salinization is the accumulation of water-soluble salts within soil layers above a certain level that adversely affects crop production, environmental health, and economic welfare. Soil salinity is described and characterized in terms of the concentration and composition of the soluble salts.
