Abstract:Soil carbon persistence in forests plays a pivotal role in regulating terrestrial feedback to climate change. However, the relative contributions of biotic and abiotic factors in controlling geographic variation of forest soil carbon turnover time (τsoc) remains unclear. Here, we first sampled soils from 12 permanent forest plots across eastern China and detected higher radiocarbon‐derived mean turnover time of soil organic carbon in the deep (30–100 cm; 2,087 ± 246 years) than the surface (0–30 cm; 249 ± 80 y… Show more
