dc.description.abstractGreenhouse gas (GHG) emissions from crop residue management have been studied extensively, yet the effects of harvesting more than one crop residue in a rotation have not been reported. Here, we measured the short-term changes in methane (CH<sub>4</sub>), nitrous oxide (N<sub>2</sub>O), and carbon dioxide (CO<sub>2</sub>) emissions in response to residue removal from continuous corn (<i>Zea mays</i> L.) (CC) and corn&ndash;wheat (<i>Triticum aestivum</i> L.)&ndash;soybean (<i>Glycine max</i> L. Merr.) (CWS) rotations in the Mid-Atlantic USA. A first experiment retained five corn stover rates (0, 3.33, 6.66, 10, and 20 Mg ha<sup>&minus;1</sup>) in a continuous corn (CC) in Blacksburg, VA, in 2016 and 2017. Two other experiments, initiated during the wheat and corn phases of the CWS rotation in New Kent, VA, utilized a factorial combination of retained corn (0, 3.33, 6.66, and 10.0 Mg ha<sup>&minus;1</sup>) and wheat residue (0, 1, 2, and 3 Mg ha<sup>&minus;1</sup>). Soybean residue was not varied. Different crop retention rates did not affect CO<sub>2</sub> fluxes in any of the field studies. In Blacksburg, retaining 5 Mg ha<sup>&minus;1</sup> stover or more increased CH<sub>4</sub> and N<sub>2</sub>O emissions by ~25%. Maximum CH4 and N<sub>2</sub>O fluxes (4.16 and 5.94 mg m<sup>&minus;2</sup> day<sup>&minus;1</sup>) occurred with 200% (20 Mg ha<sup>&minus;1</sup>) retention. Two cycles of stover management in Blacksburg, and one cycle of corn or wheat residue management in New Kent did not affect GHG fluxes. This study is the first to investigate the effects of crop residue on GHG emissions in a multi-crop system in humid temperate zones. Longer-term studies are warranted to understand crop residue management effects on GHG emissions in these systems.en
