Table 3 Soil analysis results for SOC and labile organic carbon at 0–30 cm soil depth for different stand density levels. Values are the mean ± standard deviation (SD). Different lowercase letters (a, b, c) indicate significant differences between stand density levels (P < 0.05). SOC, soil organic carbon; DOC, soil dissolved organic carbon; MBC, microbial biomass carbon; LFOC, light fraction organic carbon; ROC, readily oxidized carbon. 27a, 27-year-old stand; 36a, 36-year-old stand; 48a, 48-year-old stand
