TRAITS MORPHOPEDOLOGIQUES DUNE PENEPLAINE DE SAVANE ARBOREE A BROBO AU CENTRE DE LA COTE DIVOIRE

A morphopedological study was conducted on a 10 hectares plot of land near the village of Bopri in the sub-prefecture of Brobo. The objective was to identify the soils of this site in order to have a general overview of the soils of this region, which is poorly known from a pedological point of view and where the rare information relating to the soils goes back decades. Its implementation required the opening of 7 soil pits distributed homogeneously over the entire site in order to guarantee the representativeness of the information collected during these investigations. In total, this study revealed that this site contains a large proportion of typically ferralitic soils with deep indurations Haplic Ferralsols (Endopetric). However, in addition to this dominant category, anthropogenic Leptosols are found, which are characterised by a continuous mass of duricrust starting less than 25 cm deep and whose formation is consecutive of human activities.
