A new paper in Soil Biology and Biochemistry co-authored by Ecohydrology Research Group member Dr. Fereidoun Rezanezhad presents the mechanisms underlying how soil freeze-thaw cycles induces a pulse of nitrous oxide (N2O) emissions and how the soil aggregates and carbon and nitrogen substrates fuel this pulse. The results indicate that aggregate disruption under soil freezing and thawing does not play a significant role in providing substrates for N2O emissions and a larger N2O emission due to longer freezing durations were associated with a delayed decrease in microbial biomass.
