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, we
present preliminary results on our research on interrill carbon (C)
erosion, SOM transport by rill erosion and the stationarity of C
erosion during the Holocene. None of those issues has been incorporated
comprehensively and with global coverage in the debate on the role of C
erosion in the global C cycle. Therefore, we argue that only an
eco-geomorphologic perspective on organic C movement through landscapes
can reconcile the two positions.
