SOC dynamics and soil redistribution modelling in Mediterranean agroecosystems

 The main factor for soil redistribution is runoff through the gully system triggering the selective removal of finer soil particles mobilized the rich carbon fine fraction affects the depletion of soil particles and, therefore, SOC.  Settling velocity measurements provide direct information on soil aggregate distribution with implications on soil and SOC transportability that can be used in soil erosion modelling.  The combination of the spatially distributed SPEROS-C model combined with 137Cs measurements is a potential tool to evaluate erosion induced carbon fluxes.
