  • Historically it has been maintained that soil organic carbon (SOC) is stabilized through interactions with mineral interfaces. Here the authors use cryo-electron microscopy and spectroscopy to show that SOC interactions can also occur between organic forms in patchy, disordered structure.

  • Soil respiration rates have almost doubled between 2015-2020 with increased heterotrophic microbial carbon mineralization and microbial biomass, suggesting an increase in the bioavailability of organic carbon, according to an analysis of long-term data from the Hubbard Brook Experimental Forest, U.S.
