Global climate changes is transforming our soils. In our long-term soil warming experiment in the Barre Woods tract at Harvard Forest, a 5C elevation in soil temperature has increased respiration rates and resulted in a net loss of soil carbon and increase nitrogen mineralization. In order to link microbial metabolism with soil biogeochemistry, we measured cellular metabolism and soil organic matter chemistry using both next generation sequencing and high-resolution mass spectrometry (MS).
