Abstract:
Several kinds of sodium-affected soils, mainly Solonetzic Grumusols are extensive in the Jordan valley. For most, the salinity and high levels of exchangeable sodium are due to high water tables. However, some older soils are believed to have been subject to prolonged deposition of airborne salts. Four related kinds of sodium-affected soils are common in the northern part of the valley: (a) soils with a high groundwater table in which the highest concentrations of salts and exchangeable sodium are in the upper layers; (b) soils with a somewhat deeper water table where the high salinity and alkalinity are in deeper layers; (c) soils which had high groundwater tables in the past but which have been leached to some extent; and (d) soils which never suffered from a high water table, but nevertheless are alkaline and also somewhat saline in the deeper layers. The above-mentioned soils, except those listed under (a) have been subject to some leaching. In the southern part of the valley most of the soils are highly saline and the low rainfall precludes natural leaching. Major characteristics of the soils are related to high salinity and high levels of exchangeable sodium. Typical Solonetz profiles are restricted to soils with moderately low clay content. At higher clay contents soil turbation processes may preclude formation of a textural B-horizon. © 1972.

Sodium-affected soils in the Jordan valley
Several kinds of sodium-affected soils, mainly Solonetzic Grumusols are extensive in the Jordan valley. For most, the salinity and high levels of exchangeable sodium are due to high water tables. However, some older soils are believed to have been subject to prolonged deposition of airborne salts. Four related kinds of sodium-affected soils are common in the northern part of the valley: (a) soils with a high groundwater table in which the highest concentrations of salts and exchangeable sodium are in the upper layers; (b) soils with a somewhat deeper water table where the high salinity and alkalinity are in deeper layers; (c) soils which had high groundwater tables in the past but which have been leached to some extent; and (d) soils which never suffered from a high water table, but nevertheless are alkaline and also somewhat saline in the deeper layers. The above-mentioned soils, except those listed under (a) have been subject to some leaching. In the southern part of the valley most of the soils are highly saline and the low rainfall precludes natural leaching. Major characteristics of the soils are related to high salinity and high levels of exchangeable sodium. Typical Solonetz profiles are restricted to soils with moderately low clay content. At higher clay contents soil turbation processes may preclude formation of a textural B-horizon. © 1972.
