  abstract = {{T}hee effects of land-use change ({LUC}) on soil carbon ({C}) balance has to be taken into account in calculating the {CO}2 savings attributed to bioenergy crops(1-3). {T}here have been few direct fieldmeasurements that quantify thee effects of {LUC} on soil {C} for the most common land-use transitions into sugar cane in {B}razil, the world's largest producer(1-3). {W}e quantified the {C} balance for {LUC} as a net loss (carbon debt) or net gain (carbon credit) in soil {C} for sugar-cane expansion in {B}razil. {W}e sampled 135 field sites to 1 m depth, representing three major {LUC} scenarios. {O}ur results demonstrate that soil {C} stocks decrease following {LUC} from native vegetation and pastures, and increase where cropland is converted to sugar cane. {T}he payback time for the soil {C} debt was eight years for native vegetation and two to three years for pastures. {W}ith an increasing need for biofuels and the potential for {B}razil to help meet global demand(4), our results will be invaluable for guiding expansion policies of sugar-cane production towards greater sustainability.},
