英文摘要Protection by metal (hydr) oxides is one of the key mechanisms for the long‐term stabilization ofsoil organic carbon (SOC). However, the source and turnover of (metal‐) bound organic carbon (OC) in soils arepoorly constrained. Here we present the first large‐scale study on the 13C and 14C characteristics of bound OC in15 wetland and upland soil profiles. We find that bound OC has similar δ13C as SOC, suggesting no preferencefor plant‐ or microbe‐derived carbon. However, bound OC Δ14C is more negative than SOC in wetland but notupland mineral soils, and decreases with increasing reactive minerals. Hence, in contrast to the conventionalassumption, bound OC is better preserved relative to SOC in wetlands with high contents of reactive metals. Ourfinding highlights the dynamic exchange of bound OC with SOC in upland soils and calls for a betterrecognition of reactive metals in stabilizing OC in wetlands.
