Towards a better understanding of the role of Fe cycling in soil for carbon stabilization and degradation
Iron (Fe) minerals play an important role in stabilizing soil organic carbon (SOC). Fe-
mediated SOC protection is mainly achieved through adsorption, co-precipitation, or …

[HTML][HTML] Interactions between organic matter and Fe oxides at soil micro-interfaces: Quantification, associations, and influencing factors
Q Li, W Hu, L Li, Y Li - Science of the Total Environment, 2023 - Elsevier
Iron (Fe) oxides are widely recognized to prevent the degradation of organic matter (OM) in
environments, thereby promoting the persistence of organic carbon (OC) in soils. Thus …

Iron-mediated organic matter decomposition in humid soils can counteract protection
Soil organic matter (SOM) is correlated with reactive iron (Fe) in humid soils, but Fe also
promotes SOM decomposition when oxygen (O2) becomes limited. Here we quantify Fe …

Where and why do particulate organic matter (POM) and mineral-associated organic matter (MAOM) differ among diverse soils?
Soil organic matter (SOM) has often been separated into operational physical fractions, such
as particulate organic matter (POM) and mineral-associated organic matter (MAOM), to …

Sphagnum increases soil's sequestration capacity of mineral-associated organic carbon via activating metal oxides
Y Zhao, C Liu, X Li, L Ma, G Zhai, X Feng - Nature Communications, 2023 - nature.com
Sphagnum wetlands are global hotspots for carbon storage, conventionally attributed to the
accumulation of decay-resistant litter. However, the buildup of mineral-associated organic …

Iron mineral dissolution releases iron and associated organic carbon during permafrost thaw
It has been shown that reactive soil minerals, specifically iron (III)(oxyhydr) oxides, can trap
organic carbon in soils overlying intact permafrost, and may limit carbon mobilization and …
