                                    Citation: McCarty, G., Ritchie, J. 2006. Impacts of soil redistribution on carbon distribution and biogechemistry with agricultural landscapes: Implications for carbon sequestration [abstract]. International Conference On Soil Protection Strategy-Needs and Approaches for Policy Support. p. 34-36.Interpretive Summary:
                                Technical Abstract: The impact of soil redistribution associated with agricultural activites on carbon dynamics with the terrestrial ecosystem is not well understood.  Recent modeling studies indicate that soil erosion and terrestrial sedimentation may establish ecosystem disequilibria that promote carbon sequestration within the terrestrial biosphere.  Improved measurements of soil redistribution and biochemical modeling of resulting soil carbon distribution are needed to fully understand overall impacts on carbon sequestration at watershed and regional scales.  The use of natural and anthropogenic radionuclides as tracers of soil movement in landscapes will be discussed as well as efforts to measure and biogeochemical model of carbon redistribution and stability within agricultural landscapes.  The magnitude of the impact of soil redistribution on terrestrial carbon dynamics needs better evaluation before scientifically sound policies on terrestrial carbon sequestration can be established.
