Soil doesn't show much geochemical variation. δ13C(SOM) varies from –14.2‰ to –22.6‰ with an overall variability of 8.5‰. What does this indicate?

Major and trace element analysis are performed and different proxies are used on a 2m long soil profile. This does not show depth vise geochemical variation. However, δ13C(SOM) varies from –14.2‰...
