The study was realized to evaluate the soil fertility potential in cocoa in Côte d’Ivoire. A total of 140 farmers’ plots from 14 producing regions were randomly selected for soil sampling in the 0-20 cm horizon. Soil samples for chemical analyses were performed on the following parameters: pH-water, total organic C, total N, available P and exchangeable cations. Both organic C and total N were low. Although, available P was rated high Low. Cation exchange capacity (CEC) was an indication that the soils have low potential for plant nutrients retention. A guided fertilizer usage should be recommended to cocoa farmers to boost the productivity of the cash crop.

Abstract: (french)
L’étude a été réalisée dans le but d’évaluer le potentiel de fertilité des sols sous cacaoyers en Côte d’Ivoire. Un total de 140 parcelles d’agriculteurs de 14 régions productrices de cacao a été choisi pour l'échantillonnage du sol dans l'horizon 0-20 cm. Les analyses chimiques des échantillons de sols au laboratoire ont été réalisées sur les paramètres suivants: pH eau, C total, N total, P assimilable, le K, Ca, Mg, le B, Fe, Al, Zn, Cu, Mn et CEC. Les analyses ont montré que, dans tous les sols, le C organique et le N total étaient faibles, que 14 % des sols des cacaoyères prospectées avaient un potentiel de fertilité bas et 79 %, un potentiel de fertilité moyen pour la cacaoculture. Seulement, 7 % des sols ont un potentiel de fertilité élevé pour la cacaoculture.
