Emission of greenhouse gases, including nitrous oxide (N2O), from open beef cattle feedlots is becoming an environmental concern; however, research measuring emission rates of N2O from open beef cattle feedlots has been limited. This study was conducted to quantify N2O emission fluxes as affected by pen surface conditions, in a commercial beef cattle feedlot in the state of Kansas, USA, from July 2010 through September 2011. The measurement period represented typical feedlot conditions, with air temperatures ranging from -24 to 39°C. Static flux chambers were used to collect gas samples from pen surfaces at 0, 15, and 30 minutes. Gas samples were analyzed with a gas chromatograph and from the measured concentrations, fluxes were calculated. Median emission flux from the moist/muddy surface condition was 2.03 mg m−2 hour−1, which was about 20 times larger than the N2O fluxes from the other pen surface conditions. In addition, N2O peaks from the moist/muddy pen surface condition were six times larger than emission peaks previously reported for agricultural soils.

Abstract Three herds (36-122 head per herd) of Angus cattle (cow-calf or yearling heifers) located at the Wye Research and Education Center, Queenstown, MD, were tagged with one of three ear tag formulations. On 17 May one of the herds was tagged with Optimizer tags (2 per head) and on 2 Jun the other 2 herds were tagged with Python tags (2 per head) or experimental YT-615 tags (1 per head). A herd of mixed-breed beef cattle located approximately 4 km from the treated cattle served as an untreated control. Fly density was determined by making biweekly counts on 15 cattle in each of the herds. Counts were made ol face flies/face, horn flies/animal, and stable flies/4 legs. Two (Optimizer herd) or 3 (other 2 herds) pretreatment and 11 or 10 posttreatment counts were made.
