NGEE Arctic and EMSL collaborate to provide molecular-scale insights into SOM degradation
Determine chemical composition during degradation of soil organic matter (SOM) in controlled incubation studies
Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) was used to assess SOM molecular composition. Amino sugars, peptides, and carbohydrate-like compounds are disproportionately more susceptible to microbial degradation than others in the Arctic soil under warming.
Biochemical composition is proposed to improve process-based models of SOM degradation and climate feedbacks
