Mitigation of nitrous oxide emissions in the context of nitrogen loss reduction from agroecosystems: Managing hot spots and hot moments

Wagner-Riddle, CBaggs, EMClough, TimothyFuchs, KPetersen, SO2022-05-032020-08-272020-122020-08-041877-3435PI3HL (isidoc)https://hdl.handle.net/10182/14920Across landscape and field scales, nitrogen (N) transformation rates are enhanced in hot spots (HS) and transient hot moments (HM), leading to losses of environmentally reactive N. Nitrous oxide (N₂O) emission trends follow these spatial and temporal patterns. Consequently, landscape features can accelerate N₂O emissions, and significant fractions of total annual emissions occur in these N₂O emissions HS and HM. In agroecosystems, naturally occurring and management-induced HS and HM can be exacerbated or ameliorated through mitigation management practices. Although mitigation practices have been recommended for reduction of N₂O emissions, these have not explicitly targeted HS and HM. Here we review, and synthesize, N₂O mitigation practices with an emphasis on how they can be aligned to reduce the occurrence of HS and HM of N₂O emission.pp.46-53en© 2020 Elsevier B.V.
