The use of Cesium-137 (137Cs) as a potential environmental
marker was examined for estimating soil erosion
induced carbon losses on slopping agricultural
land. Depth-wise incremental soil samples were taken
from uneroded reference sites and four levels of cultivated
slopping lands representing different erosion
phase in Doon valley region of India. Comparing the
137Cs inventories for eroded sites with the reference
inventory, the erosion rates were computed. The estimated
erosion rates were then compared with the
actual measured values of erosion at each erosion
phase. Since soil erosion preferentially removes the
finer soil particles, these results were used to assess
erosion induced loss of OC. The result indicated that
erosion in different phases relocate 137 kg C ha–1 in
slightly eroded plots to 384 kg C ha–1 in severely
eroded plots which in turn contributes to 27 to
77 kg C ha–1 the atmosphere as net source of C respectively
