  abstract = {{S}oil organic matter plays a crucial role in the global carbon cycle, yet the magnitude and direction of changes in soil carbon content following vegetation shifts in the tropics remain highly debated. {M}ost studies have focused on short-term changes, typically spanning only a few months or years. {I}n this study, we investigated the medium-term dynamics of organic matter at a site where savanna, protected from fire for 58 years, has gradually transitioned to woodland vegetation. {N}atural 13{C} abundance analysis combined with particle-size fractionation was used to characterize the changes in {SOM} over time. {W}hile carbon content remains relatively stable, delta 13{C} exhibits a distinct shift, particularly in the surface layers, reflecting the gradual replacement of savanna-derived carbon with tree-derived carbon. {A}ll fractions were influenced by the inputs and outputs of carbon from both savanna and tree sources. {I}n the coarse fractions, most of the carbon originates from trees; however, a significant proportion of savanna-derived carbon (ranging from 10% to 40%, depending on the fraction, depth, and patch) persists, likely in the form of black carbon. {I}n the fine fractions, nearly half of the carbon (40% to 50%) remains derived from the savanna, highlighting the greater stability of organic matter that is physically bound to clays and protected within microaggregates.},
