Short summary

We quantified the changes in stem and soil nitrous oxide (N₂O) fluxes with forest conversion to cacao agroforestry in the Congo Basin, Cameroon. All forest and cacao trees consistently emitted N₂O, contributing 8–38 % of the total (soil and stem) emissions. Forest conversion to extensively managed (>–20 years old) cacao agroforestry had no effect on stem and soil N₂O fluxes. Our results highlight the importance of including tree-mediated fluxes in the ecosystem-level N₂O budget.
