Comparison of CO₂ fluxes, soil temperatures, and snow depth with other studies.

<p>Soil carbon and nitrogen, snow depth and ranges, average CO₂ fluxes, and contribution of winter CO₂ emissions to total emissions among studies that reported CO₂ emissions in the cold season in agricultural ecosystems. Abbreviations: C total soil carbon; N total soil nitrogen; NE not estimated; MWST mean winter soil temperature; RSD range of snow depth.</p><p>Comparison of CO₂ fluxes, soil temperatures, and snow depth with other studies.
