The Root of the Matter: Soil Carbon Mobilization in the Rhizosphere

Lead Institution
University of Massachusetts Amherst
Principal Investigator
Marco Keiluweit
Project type
Large-Scale EMSL Research
The exploratory work we propose aims to improve mechanistic understanding of links among rhizodeposition of organic compounds by plant roots, microbial growth and activity, and the strength of…

Impact of natural organic matter on U speciation and mobility in groundwater

Lead Institution
Environmental Molecular Sciences Laboratory
Principal Investigator
John Bargar
Project type
Exploratory Research
Uranium (U) contamination of aquifers is a persistent problem at DOE legacy ore processing sites and, contrary to initial predictions, many plumes are not attenuating with natural groundwater…

The Role of Anaerobic Microsites in Soil Carbon Storage

Lead Institution
Stanford University
Principal Investigator
Scott Fendorf
Project type
Large-Scale EMSL Research
The overarching goal of this project is to quantitatively place the importance of metabolic constraints in anaerobic microsites on the rate of soil organic matter (OM) oxidation, and thus advance our…
