Interpretive Summary:

Technical Abstract: Harvesting stover can impact soil and microclimate properties, which in turn may impact the powerful greenhouse gas, nitrous oxide. Many studies only report short-term nitrous oxide flux following fertilizer events or the growing season. In climates that experience freeze-thaw cycles, nitrous oxide emission during early spring thaw can represent a substantial portion of the annual nitrous oxide emission. Nitrous oxide data from four years (planting to planting) will be discussed in the context of harvesting stover as bioenergy feedstock.
