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 …

The influence of native soil organic matter and minerals on ferrous iron oxidation
Fe (II) oxidation by O 2 is an important process generating Fe (oxyhydr) oxides, which play
sorptive, structural and electron-transfer roles in soils. Here we explored how native …

Soil organic carbon accrual due to more efficient microbial utilization of plant inputs at greater long-term soil moisture
High long-term soil moisture may either stimulate or inhibit soil organic carbon (SOC) losses
through changes to mineral and chemical composition, and resultant organo-mineral …

The primacy of temporal dynamics in driving spatial self-organization of soil iron redox patterns
This study investigates mechanisms that generate regularly spaced iron-rich bands in
upland soils. These striking features appear in soils worldwide, but beyond a generalized …

Soil CO2 and O2 Concentrations Illuminate the Relative Importance of Weathering and Respiration to Seasonal Soil Gas Fluctuations
Soil CO2 and O2 cycles are coupled in some processes (eg, respiration) but uncoupled in
others (eg, silicate weathering). One benchmark for interpreting soil biogeochemical …
