James Amonette

Project type

Large-Scale EMSL Research

Soils contain large amounts of organic carbon (OC) and serve as both sources and sinks for atmospheric C. However, little is known about the structural chemistry of stabilized soil OC or the…

Connecting Meta-omics with Nutrient Cycle Modeling Using FTICR Mass Spectrometry
