Nonlinear nitrous oxide (N2O) response to nitrogen fertilizer in on‐farm corn crops of the US Midwest
Abstract
Row‐crop agriculture is a major source of nitrous oxide (N 2 O) globally, and results from recent field experiments suggest that significant decreases in N 2 O emissions may be possible by decreasing nitrogen (N) fertilizer inputs without affecting economic return from grain yield. We tested this hypothesis on five commercially farmed fields in Michigan, USA planted with corn in 2007 and 2008. Six rates of N fertilizer (0–225 kg N ha−1) were broadcast and incorporated before planting, as per local practice. Across all sites and years, increases in N 2 O flux were best described by a nonlinear, exponentially increasing response to increasing N rate. N 2 O emission factors per unit of N applied ranged from 0.6% to 1.5% and increased with increasing N application across all sites and years, especially at N rates above those required for maximum crop yield. At the two N fertilizer rates above those recommended for maximum economic return (135 kg N ha−1), average N 2 O fluxes were 43% (18 g N 2 O–N ha−1 day−1) and 115% (26 g N 2 O–N ha−1 day−1) higher than were fluxes at the recommended rate, respectively. The maximum return to nitrogen rate of 154 kg N ha−1 yielded an average 8.3 Mg grain ha−1. Our study shows the potential to lower agricultural N 2 O fluxes within a range of N fertilization that does not affect economic return from grain yield.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
