The present study aims to determine the spatial gradient of organic matter in soil-litter mixtures as a function of the distance to iroko associated with cocoa trees. The demonstration of the preservation of iroko is carried out thanks to a floristic inventory and a survey ethnobotany from 323 farmers. The fertility of cocoa-growing soils was estimated using spatial organic matter measurement in 12 cocoa plantations of 1,5 to 2 ha associated with iroko. A total of 48 composite litter samples were collected at 20 cm along the spatial gradient of the iroko at distances of 1-2 m, 2-4 m and 4-6,5 m and then in the control (without iroko). With 73% of citation, populations are favorable to its preservation in cocoa agroforests. Prized for its artisanal and medicinal uses, it improves soil fertility outside the shade provided to cocoa trees. Its average organic matter content in cocoa-growing soils is very significant. The spatial gradient of M. excelsa has had a significant impact on the amount of organic matter less than 6% in the iroko rhizosphere while it reaches 6 to 8% in cocoa trees. Its preservation in cocoa trees contributes to improving the properties of poor soils. However, differential processes ultimately affect the decomposition rates of organic matter, hence the separation of cocoa trees by at least 10 m to benefit from the supply of carbon, nitrogen and phosphorus ions.
