  abstract = {{C}hanges in residue management may help sustain land productivity, and may have noticeable consequences in the global carbon budget when large areas are involved. {T}he effects of sugarcane residue management on topsoil carbon were assessed in a clayey {O}xisol of {B}razil, largest world's producer of sugarcane. {T}he carbon concentration of the whole soil and particle-size fractions were determined in a long-duration sugarcane plantation (50 years), with either a pre-harvest residue burning ({BUR}) or a 6-year green trash management ({MUL}, residue mulching). {S}oil carbon concentrations were greater in {MUL} than in {BUR}. {T}he difference was significant at a 0-5 cm depth (25.2 versus 21.0 g {C} kg(-1)) but not at 5-10 cm (22.3 versus 20.5 g {C} kg(-1)); nevertheless it was significant at 0-10 cm (23.7 versus 20.7 g {C} kg(-1)). {T}his difference resulted in carbon sequestration in {MUL}, which arnounted to 0.65 {M}g {C} ha(-1) year(-1) at 0-10 cm depth and corresponded to 14% of aboveground residue carbon returned to the soil. {D}ifferences in soil carbon between {MUL} and {BUR} mainly affected the fraction < 2 mu m. {I}t was hypothesized that the preferential enrichment in fine fractions resulted in a long-term carbon storage.
