Happy to announce the publication of:
Williams EK, ML Fogel, AA Berhe and AF Plante. (2018) Distinct bioenergetic signatures in particulate versus mineral-associated soil organic matter. Geoderma. 330:107-116. doi:10.1016/j.geoderma.2018.05.024. This paper was part of Elizabeth Williams’s research program while at the University of Calfornia, Merced, which we expanded on using thermal analysis of the density fractionation samples. We found that light-fraction particulate SOM and heavy-fraction mineral-associated SOM had distinct thermal analysis, and thus bioenergetic, and chemical signatures. These signatures provided further insight into their composition and mechanisms of stabilization in soils from a climosequence from the Sierra Nevada Mountains in California.
