The results of this study suggested that C. odorata-based fallows
have the potential to improve soil quality status in humid savannah
zones of Ivory Coast. Significant inputs in nitrogen, phosphorus and
potassium through leaf litter, enhanced SOC and total N storage, improved
water infiltration capacity and increased N-mineral pool and
soil macrofauna conservation are the main beneficial consequences
of C. odorata invasion. As a result, C. odorata fallows or mulch
cropping systems could be one of the options to sustainably improve
and maintain soil fertility in the buffer zone of the Lamto Reserve. In
order to achieve this ultimate goal, the implementation of further
multi-location and chronosequence trials should be undertaken
to confirm current findings and also assess the impact of C. odorata
fallows on crop yield (maize and yam), as well as the economic viability
of such cropping system.
