Abstract

Recent research on the contribution of soil erosion on agricultural land to atmospheric carbon dioxide (CO2) emphasizes either the contribution of soil organic matter (SOM) mineralization during transport as source for atmospheric CO2, or the deep burial of SOM-rich sediment in agricultural landscapes as a sink. The contribution of either process is subject to a controversial debate. In this letter, the AA. present preliminary results on their research on interrill carbon (C) erosion, SOM transport by rill erosion and the stationarity of C erosion during the Holocene. In conclusion, they argue that only an eco-geomorphologic perspective on organic C movement through landscapes can reconcile the two positions
