Abstract A partial balance of mineral N is given for the basins of two coastal rivers in a forest zone in the Ivory Coast. The dry and wet depositions on the basin surfaces is given for particulate matter (NO3 −, NH4 +). The quantity of mineral N washed away in the rivers is evaluated. The losses from leaching of the soils by rainwater are about 0.33 to 1.0% of the atmospheric depositions for NH4 +−N and 2.2 to 5.8% for NO3 −−N. The yearly atmospheric input of N compounds to the ecosystem, about 1.4 g N m−2 y−1, is at least 14% of mineral N formed in the soils and is therefore quite significant.
