Nitrogen and carbon addition changed nitrous oxide emissions from soil aggregates in straw-incorporated soil

Purpose The effects of straw incorporation on soil nitrous oxide (N 2 O) emission at the soil aggregate scale have yet to be elucidated, especially with supplemental nitrogen (N) and/or organic carbon (OC). The objective of this study was to evaluate N 2 O emission across different size soil aggrega...

Zusammenfassung:	Purpose The effects of straw incorporation on soil nitrous oxide (N 2 O) emission at the soil aggregate scale have yet to be elucidated, especially with supplemental nitrogen (N) and/or organic carbon (OC). The objective of this study was to evaluate N 2 O emission across different size soil aggregates of 6-year straw-incorporated soil as affected by exogenous N and OC treatments. Materials and methods In the present study, the N 2 O emission from different particle size soil aggregates (> 2, 1–2, 0.25–1, and 1 mm aggregates and
