A field study conducted over five growing seasons (2013-2017) assessed the effect of long-term fertilization history and crop rotation on growing season nitrous oxide (N2O) and carbon dioxide (CO2) emissions, wheat yield, wheat N uptake, N2O emission intensity and soil properties on Gray Luvisolic soils. Long-term fertility treatments included check, manure, NPKS, NPK and PKS fertilizers in two contrasting crop rotations: a 2-year of wheat (Triticum aestivum L.)-fallow (WF), and a 5-year wheat (Triticum aestivum L.)-oat (Avena sativa)-barely (Hordeum vulgare L.) - alfalfa (Medicago sativa)/brome (Bromus tectorum) hay (WOBHH). Rotation significantly affected cumulative growing season N2O emissions and, within each rotation, long-term fertilizer or manure N additions increased N2O emissions over the check. Average, cumulative growing season N2O emissions from the 5-year rotation were 1.29 kg N2O-N ha-1, significantly higher than the 0.58 kg N2O-N ha-1 in the WF rotation, but N2O emission intensities were comparable between to the two rotations. Cumulative N2O emissions were positively correlated to total soil N (0-15 cm) and wheat N uptake, but N2O emission intensities were negatively correlated to total soil N.
