Proportion of N and P pool in vegetation and organic soil.
Capital letters indicate significant differences in the proportion of N or P in total vegetation at different sites; lowercase letters indicate significant differences in the proportion of N or P in organic soil at different sites (P < 0.05).

The N:P ratio in vegetation and organic soil.
Capital letters indicate significant differences in the N:P ratio of vegetation at different sites. Lowercase letters indicate significant differences in the N:P ratio of organic soil at different sites (P < 0.05).
