|a Organic carbon persistence in soils is predominantly controlled by physical accessibility rather than by its biochemical recalcitrance. Understanding the regulation of soil iron (Fe) and aluminum (Al) (hydr)oxides, playing a dominant role in mineral protection, on soil organic carbon (SOC) would increase the reliable projections of the feedback of terrestrial ecosystems to global warming. Here, we conducted a continental-scale survey in China (341 sites) and a global synthesis (6786 observations) to reveal the global distributions of Fe/Al (hydr)oxides and their effects on SOC storage in terrestrial ecosystems. We generated the first global maps of soil Fe/Al (hydr)oxides with high accuracy (with R2 more than 0.74). The variance decomposition analysis showed that Fe/Al (hydr)oxides explained the most proportion of variance for topsoil (0-30 cm) and subsoil (30-100 cm) SOC. Therefore, soil Fe/Al (hydr)oxides play a stronger role in explaining the spatial variation of SOC than well-studied climate, edaphic, vegetated, and soil depth factors in both topsoil and subsoil. Collectively, the planetary-scale significance of soil Fe/Al (hydr)oxides for SOC highlights that soil Fe/Al (hydr)oxides should be incorporated into Earth System Models to reduce the uncertainty in predicting SOC dynamics
