  abstract = {{I}n {S}udano-{S}ahelian regions, wetting-drying cycles may affect soil carbon mineralization in soil already poor in carbon. {C}onservation agriculture systems by improving crop residues return to soil is given to increase soil organic carbon and soil fertility. {W}e studied the effect of biomass management regimes and wetting-drying cycles on soil carbon stocks and mineralization. {A} 50-day experiment was set up to compare carbon mineralization under two biomass management regimes, with and without mulch, using three soil wetting treatments. {W}etting the soil and mulching increased soil carbon mineralization. {H}owever, wetting-drying cycles did not increase the soil carbon mineralization as compared with soils kept moist. {D}uring the experiment, the total carbon mineralization from the dry soils was low, 0.63 t{C} ha(-1) and 0.53 t{C} ha-{I} respectively for soils with and without mulch. {T}otal carbon mineralization from soil without mulch was 1.40 t{C} ha(-1) with wetting-drying cycles and 1.51 t{C} ha(-1) for soils that were kept moist. {T}otal carbon mineralization from soils with mulch was 1.70 t{C} ha(-1), regardless of whether the soils had wetting-drying cycles or were kept moist. {I}n our context, characterized by very little crop residues and rapid mineralization of this biomass, the conservation agriculture systems do not seem sufficient to increase soil organic carbon stocks.},
