Agroforestry, a farming system combining trees with crops and sometimes livestock, is considered a sustainable approach to mitigating climate change. An experiment was conducted at the National Agricultural Research Centre in Divo, combining cocoa trees with Ricinodendron heudelotii (Akpi). The aim was to evaluate interactions within this system by analyzing soil physical and chemical properties. Four years after planting, soils under shaded cocoa (with R. heudelotii) and cocoa grown in full sun were compared. Parameters analyzed included texture, pH, cation exchange capacity (CEC), organic carbon, total nitrogen, available phosphorus, and trace elements. Results showed that soils in both systems were clayey siltysandy. However, pH improved in the agroforestry system. The C/N ratio was normal in full sun (8.5) but higher under agroforestry (18). Organic matter content remained below recommended levels in both systems. CEC values were within acceptable ranges for cocoa, with slightly higher values in the agroforestry system. Total phosphorus was also higher under R. heudelotii. However, the Mg/K ratio was below recommended levels in both systems. Overall, the presence of R. heudelotii positively influenced several soil fertility parameters compared to full sun cultivation.
