Also, the relationship between soil erosion and deposition rates,
using 137Cs inventory-conversion models and storage and loss of soil organic carbon stocks was examined. To
do this, 137Cs activity and SOCS were measured in thirty-two sample sites from different hillslope components
in cultivated and forested areas. The simplified mass-balance model and diffusion and migration model estimated
very high erosion rates of 6.43 and 40.3 t ha−1 yr−1 in the shoulder component of forest and cultivated areas,
respectively. In both disturbed (cultivated) and undisturbed (forested) soils, positive and statistically significant
relationships were found between the SOCS and 137Cs inventory. Consequently, 137Cs could be used directly for
quantifying dynamics of SOC in soil redistribution relationship as affected by soil erosion. Statistical analyses
also indicated that the 137Cs activity and inventory, SOCS and erosion/deposition were significantly affected by
landform components and land use types.
