Figure 2

Modeled mean residence times (MRT) of density fractions from high-severity burn and unburned control soils at two depths: a) 0 cm to 5 cm, and b) 5 cm to 15 cm. c) Δ14C (‰) of coarse charcoal removed from the 0 cm to 5 cm and 5 cm to 15 cm depths of high-severity burn and unburned soils. Error bars are the standard error of either 5 or 6 experimental replicates. Asterisks (*) indicate significant differences between control and burnt soils at α = 0.05.
