This study was carried out in the Kokumbo sub-prefecture in central Côte d'Ivoire to assess the impact of cocoa-based agrosystems on the physical and chemical characteristics of cocoa soils. This region was chosen for the study because it still houses traditional agroforestry plantations based on cocoa trees and still in production. Soil pits were opened following the toposequence in each type of agroforest for the determination of the physical characteristics of the study site. For the determination of soil chemical parameters, the basic sampling was carried out at the auger at two levels of horizon: 0-20 cm and 20 - 40 cm in zigzag, following the longest diagonal for laboratory analysis. The results obtained showed that regardless of the full sun, mixed or complex forest agrosystem, the values of the fertility parameters obtained indicate overall a very satisfactory soil fertility level. Moreover, the mixed cocoa-based agro-forestry system appears to be more interesting in improving the soil structure and enrichment of available mineral elements and could be recommended to cocoa producers in the area of study.
