Iron-driven organic carbon sequestration in arid saline-alkali soils: Mechanisms of Fe-C coupling via reactive iron oxides and microaggregate stabilization

Reactive iron oxides (particularly poorly crystalline phases) act as “rust sinks” by facilitating soil organic carbon (SOC) accumulation through mechanisms such as ligand exchange, co-precipitation, and aggregate formation, owing to their high specific surface area. However, how exogenous iron input...
