This map shows the distribution of salt-affected soils in the region. Using the Fertility Capability Classification (FCC), these soils are defined (Sanchez et al., 1982) as having ‘> 4 dS/m of electrical conductivity of saturated extract at 25°C within 1 m of the soil surface’.
Within the FAO soil classification system these soils are identified as follows:
All soils in the Solonchak soil group
Other soils with saline phase
Salt Flats
The dataset is not up-to-date in respect of salinity which may have developed in irrigated areas since the early 70s, when most of the surveys used by the data source were completed. On the other hand, reclamation works may have reduced salinity or even sodicity in other areas.
