  abstract = {{I}n the buffer zone of the {L}amto {R}eserve, a protected area located in the forest-savannah transitional zone in central {I}vory {C}oast, the exotic shrub {C}hromolaena odorata has invaded abandoned fields and degraded forests. {A}s a result, they have turned into thickets that are used by local farmers as natural fallows to enhance soil fertility for food production. {H}owever, information about their impact on soil is scanty and investigations focusing exclusively on baseline data on {C} odorata fallows in humid savannahs are still lacking. {T}his study was designed to assess changes in soil physical, chemical and biological properties after the establishment of {C}. odorata fallows in humid savannahs of {I}vory {C}oast. {S}ampling sites were selected such that a portion of {C} odorata fallow was located next to the shrub savannah, the most common natural ecosystem in the area. {R}esults revealed a rise of soil organic carbon (+27.9%), total nitrogen (+36.7%), total phosphorus (+56.8%), extractable calcium (+68.3) and magnesium (+1403%) in the first 10 cm of soil beneath the {C} odorata fallow relative to the savannah. {F}urthermore, the fallow was associated with high {N}-mineral pool as {N}-{NO}3- and {N}-{NH}4+ content increased at +72.5% and +71.5%, respectively. {T}he infiltration capacity of water under {C} odorata-based fallow was markedly high and soil macroinvertebrates, mainly earthworms, showed significant increases in density and biomass. {T}he large quantity of good quality standing biomass produced by {C} odorata is likely the main factor controlling the improvement of soil quality. {T}he results suggest that there are merits for the integration of {C} odorata fallow in a cropping system for sustainable food production in the buffer zone of {L}amto {R}eserve. {T}his can also help to reduce pressure on forest islands.},
