Table 1 Results of a three-way repeated-measures ANOVA (F and P values) testing for the effects of forest type, stand age, decomposition time and their interactions on mass loss and leaf litter C and N loss from litterbags decomposed in soils in the Chinese fir and naturally occurring secondary forest stands.
