Morpho-Pedology Variations in a Pre-Saharan Region Case Ziban Soils

Abstract

During this study, we tried to highlight the main lines of the spatial evolution of the morpho-pedological characters of certain soils, on a sequence established from the geomorphological map in the region. Biskra is an Oasis located in the North-Eastern Sahara of Algeria. After a long prospection, we have established two sequences of soils which have different morphological characteristics. These variations are mainly due to the geomorphological position of the terrain and the favorable hydrological aspect in the first sequence to the formation of gypsum soils compared to the second.
