Figure 1
Amount of C extracted with (a) K2SO4 and (b) water from five forest surface (0–3 cm) soils before (non-fumigated) and after (fumigated) chloroform fumigation.
Error bars indicate the standard deviation of the mean (N = 3). The water extraction for the FR-4 and FR-5 soils was not replicated (N = 1).
