Erosion process increases the variability in the total SOC stock
both vertically through the soil profile and spatially across the
landscape; it also affects vertical and spatial variability of soil
temperature and soil moisture (Chan et al., 2007). A lot of
laboratory research has been done to study the relationship
between C flux and soil temperature and soil moisture (Borken
et al., 2003; Lee et al., 2004; Liu et al., 2002). Polyakov and Lal
(2008) studied the effect of erosion on SOC migration and
