Nitrous Oxide Production throughout the Year from Fertilized and Manured Maize Fields¹

ABSTRACT

Two field sites on a loam soil were established to monitor N₂O concentration in the soil atmosphere and rate of emission from the soil surface. The sites were cropped to maize (Zea mays L.) and managed at two high-N levels (181 or 237 kg N ha^–1). Both sites received 168 kg N ha^–1 as feedlot cattle (Bos taurus) manure (preplant-incorporated) and 13 kg N ha^–1 as NH₄NO₃ fertilizer in the row at planting. One site (Site B) received additional soil-incorporated N (56 kg N ha^–1) as urea. Fluctuations in N₂O emissions from the two sites were temporally similar, and differed only in magnitude with Site A (no additional fertilizer), emitting about 3.6 kg N₂O-N ha^–1 yr^–1 and Site B about 5.2 kg N₂O-N ha^–1 yr^–1, or about 2% of the N applied. Most of the N₂O was emitted between mid-June and the end of July when the soil was warm and NH⁺₄-N was present, and at spring thaw (late March the following year) when soils were cold and near water-saturated. High N₂O emissions during the growing season occurred following precipitation events, and hence were associated with high soil water and probably with the initiation of soil drying. Nitrous oxide production was continuous during winter months, presumably a result of denitrification. The N₂O concentration in the profile of the frozen soil increased to high levels (nearly 2000 µL L^–1 N₂O at Site B) before spring thaw. At thaw, nearly 330 d after application of the N amendments, an apparent physical release period occurred and N₂O flux was far higher (about 50 g N₂O-N ha^–1 d^–1) than at most times during the growing season.
