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).

Use of an electromagnetic technique to determine sodicity in saline‐sodic soils
Soil Use and Management, 2007Abstract Soil sodicity is an increasing problem in arid‐land irrigated soils that decreases soil permeability and crop production and increases soil erosion. The first step towards the control of sodic soils is the accurate diagnosis of the severity and spatial extent of the problem.
