Abstract

The AA. investigate the quantitative and qualitative aspects of soil organic matter (SOM) losses caused by water erosion within a small catchment in Northern Laos, under steep slopes and slash and burn agriculture. The aim was to quantify the erosion of black carbon and to identify the processes involved. The preferential erosion of black carbon compared to other SOM types can be explained by its light nature, absence of mineral interactions right after its formation and its resistance to biodegradation during transport. These results further suggest that erosion of black carbon could be a crucial process determining its fate in terrestrial ecosystems
