Exogenous organic carbon (C) inputs and their subsequent microbial mineral transformation affect the accumulation process of soil C (SOC) pool. Nevertheless, knowledge gaps exist on how different long-term forms crop straw incorporation (direct return or pyrolyzed to biochar) modifies SOC composition stabilization. This study investigated, in a 13-year field experiment, functional fractions protection by iron (Fe) oxide minerals soils amended with biochar. Under equal input, was enhanced both direct (by 43%) biochar 85%) compared non-amended conventional fertilization, but pathways. Biochar had greater efficiency increasing through stable exogenous inhibition respiration. Moreover, biochar-amended contained 5.0-fold SOCs particulate matter (POM) 1.2-fold more mineral-associated (MAOM) relative conventionally fertilized soils. Comparatively, although magnitude effect smaller, straw-derived OC preserved preferentially most MAOM. Straw increased nutrient content stimulated activity, resulting increases necromass POM MAOM 117% 43%, respectively) 72% 18%). promoted poorly crystalline (Feo) organically complexed (Fep) Fe oxides accumulation, were significantly positively correlated SOC. The results address decadal-scale effects application formation pool soil, understanding causal mechanisms can allow practices maximize content. These are great implications for better predicting accurately controlling response pools agroecosystems future changes disturbances maintaining regional balance.
