Spatial patterns and modeling of reductive ferrihydrite transformation observed in artificial soil aggregates.

Abstract

Within soils, biogeochemical processes controlling elemental cycling are heterogeneously distributed owing, in large part, to the physical complexity of the media. Here we quantify how diffusive mass-transfer limitation at the soil aggregate scale controls the biogeochemical processes governing ferrihydrite reductive dissolution and secondary iron mineral… (More)
