Abstract:The physical protection of soil organic matter through its occlusion in aggregates is a mechanism which reduces their accessibility by microorganisms. When the physically protected carbon (C) becomes accessible to the microbiota, it generates a flow of CO 2 . The objective of this study was to evaluate the C mineralization rate in macro and microaggregates of macerated and non-macerated soils under different leguminous tree, pasture, and secondary forest (capoeira). The CO 2 mineralization curves showed that m… Show more
