I would appreciate if there is any one who can share with me a recent soil salinity map of Africa or information on regional distribution of salt affected soils in the continent.
Chapter 8 Management of Salt-Affected Soils Contents ... South Africa, Turkey, India, Pakistan, and Argentina. 8.2 Development of Soil Salinity and Sodicity 273
Taking into consideration the document suggested by Anoop entitled "Salt-affected soils: South Africa", a recent version by J.P. Nell, M.C. de Villiers and M. van der Walt from "ARC- Institute for Soil, Climate and Water" is enclosed.
In addition to the included map of "Salt-affected soil in South Africa" in figure 2, you can find further maps for "Upper quartile, median and lower quartile soil salinity values for the different water management areas" in figure 3, "Upper quartile, median and lower quartile soil pH water values for the different water management areas" in figure 4, as well as "Upper quartile, median and lower quartile soil sodicity values for the different water management areas" in figure 5.
