Fig. 6From: Increased microbial sequestration of soil organic carbon under nitrogen deposition over China’s terrestrial ecosystemsPercent changes in microbial necromass C under different N forms (upper) and experimental conditions (lower). a, d Total microbial necromass C, b, e fungal necromass C, and c, f bacterial necromass C. Error bars represent the 95% bootstrap confidence intervals that were calculated by weighted effect sizes. The responses of these variables to different N forms and experimental conditions are considered significant (P < 0.05) if the 95% bootstrap confidence intervals do not overlap with zero. The between-group heterogeneities (Qb) and the probabilities (P) of the effects of N addition on microbial necromass C across different N forms and experimental conditions are shown in each panelBack to article page
