According to different estimates, there are 831 to 932 million hectares of salt affected soils – saline soils, saline-sodic soils and sodic soils. The measure of salinity is the electrical conductivity of the saturation extract (ECe) and the measure of sodicity is the exchangeable sodium percentage (ESP) or the sodium adsorption ratio (SAR).

Soil Enzymes as Indicators of Saline Soil Fertility Under Various Soil Amendments
Agriculture, Ecosystems and Environment, 2017 Soil salinity, caused by natural of anthropogenic factors, has been recognized as a challenge to cultivation. Coastal saline soil is widely distributed in China.

Soil salinity is a form of land degradation in which salts accumulate in the soil profile to an extent that plant growth or infrastructure are negatively affected. A range of both field and laboratory procedures exist for measuring soil salinity. In the field, soil salinity is usually inferred from apparent electrical conductivity (EC(a)) using a range

SALINE AND SODIC-SALINE SOIL RECLAMATION
Soil Science, 1992A column study was conducted involving the reclamation of saline and saline-sodic soils. The amount of water moving through the soils was measured as the pore volume of drainage. During saline soil reclamation, under saturated soil moisture flow, the electric conductivity (EC) of the effluent was ...

The Soil Moisture and Ocean Salinity mission
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004Surface soil moisture is a key variable of water and energy exchanges at the land surface/atmosphere interface. But currently there are no means to assess it on a global and timely fashion. Similarly, our current knowledge of sea surface salinity is very reduced. One way to overcome this issue would be to use an adequate space-borne instrument.

Abstract Salt accumulation in soils, affecting agricultural productivity, environmental health, and the economy of the community, is a global phenomenon since the decline of ancient Mesopotamian civilization by salinity. The global distribution of salt-affected soils is estimated to be around 830 million hectares extending over all ...

Spatial interpolation of soil salinity and sodicity for a saline soil in Southern Alberta
Canadian Journal of Soil Science, 1992Soil salinity and sodicity data are usually represented as contour maps based on spatially interpolated data. This study was conducted to assess two commonly used spatial interpolation methods (moving average and weighted moving average) and three forms of two-dimensional (2D) and three-dimensional (3D) kriging.

Salinity of Soils—Effects of Salinity on the Physics and Chemistry of Soils
1975In areas of low rainfall, salts formed during the weathering of soil minerals are not fully leached. Under humid conditions the soluble salts originally present in soil materials and those formed by the weathering of minerals are generally carried downward into the ground water and are transported ultimately to the oceans.

Salinity characterization of the Kenyan saline soils
Soil Science and Plant Nutrition, 2004Abstract Representative samples of the saline soils of Kenya were analysed for pH, electrical conductivity, and contents of various ions in their saturation paste / paste extracts. The salt ion contents and types were characterized using a chemical classification system.
