Comparative Study of the Cambisols of Aboisso-Comoe (Agropastoral Zone B29 Mamlanso) and Zuenoula (Agricultural Unit of the Sugar Complex)

Abstract: A comparative study was carried out on soil characterization at Aboisso-Como? and Zu?noula, located respectively in the south-east and in the center-west of C?te d'Ivoire, specifically in the agropastoral zone B29 of Mamlasso and in the sugar complex of Zu?noula. A high frequency has been set up in each of the sites. This study deals with the characterization of certain morphopedological, chemical and physicochemical parameters. Five (5) soil pits were established at Aboisso-Como? according to the topographic positions at the top, on the slope, mid-slope, slope and bottom, then three (3) pits in Zu?noula at the top of the slope, half slope and slope. All the pits were described and soil samples were taken from each horizon and analyzed in the laboratory. It is clear from this description and analysis that all soils in these study areas are Cambisols. The results indicate a good representation of Cambisols, of which two types stand out: Cambisols (Paraplinthic) at the top, at the top of slope and at mid-slope, and Cambisols (Gleyic) at the bottom of slope and at the bottom. These soils have common characteristics, in particular: organic matter contents, cation exchange capacity and exchangeable base sum values, relatively high at the surface, associated with a coarse sand-silty texture; but richer in clay with depth. These characteristics confer to them, incontestably a rather good fertility. Such soils have as their main constraint the heavy load in coarse elements.
