“…As reported by Amon et al (2001) and Yang et al (2016), NH 3 E from dairy barns varied over the course of the year, which was also observed in this study when seasonal NH 3 E changed from 0.27 to 0.92 mg sec −1 AU −1 . This finding is different from the conclusion of diurnally measured results (the variations of NH 3 E among February, July, and October were not obvious).…”

“…In the cold season, there were significant differences in both diurnal NH 3 C and NH 3 E on February 9 (p < 0.05). Yang et al (2016) observed larger diurnal variations of NH 3 E in the summer and fall at two dairy feedlots, and this pattern was confirmed in this study. In the warm season, NH 3 C was significantly lower in the EM on July 21 (p < 0.05), but showed no significant diurnal effect on July 23 (p > 0.05).…”

Diurnal and seasonal variations of odor, NH, and HS concentrations and emissions were monitored for a naturally ventilated dairy barn in a cold region. The emission factors were calculated and indoor air quality was evaluated. The overall odor and NH concentrations were higher in winter, whereas emissions were higher in the mild and warm seasons. Diurnal variation was most significant for odor emission in the mild season, when the ratio of maximum to minimum value was up to 4.6. The results can be used to estimate odor and gas emissions from other dairy barns in Canada and other cold regions.

“…Environment Protection Agency has recently petitioned to include NH 3 in the air quality standards (AAQTF, 2014). For developing countries, an increasing number of studies on NH 3 emissions have been published in the last five years, particularly in China (Qiu et al, 2014;Xu et al, 2015;Yang et al, 2016;Zhou et al, 2015).…”

Agriculture is one of the key economic sectors in Argentina and, in the last decades, the increase in prices and competitiveness of some grains has imposed important changes. In this process, crop cultivation occupied significant extensions of land areas previously dedicated to livestock farming, which in turn have experienced intensification in terms of production through an increasing share of feedlot systems. The agriculture sector is the main NH 3 emitter in Argentina, however no inventory developed locally has been thus far available. We estimated the time series 2000-2012 of NH 3 emissions, both at national and spatially disaggregated levels. National NH 3 emissions in 2012 amounted to 0.31±0.08 Tg, with the use of mineral fertilizers accounting for 43.0%, manure in pasture 32.5%, manure management 23.0% and agricultural waste burning 1.5%. Urea use was the major source of NH 3 emissions and its application on wheat and corn crops dominated the trend. Emissions from open biomass burning were estimated but not included in the national totals because of the difficulties in differentiating between agricultural (i.e., prescribed burning of savannas) and non-agricultural emission sources. Compared to this work, NH 3 emissions reported by EDGAR were 83% higher than our estimates. The time series of spatially distributed NH 3 emission estimates clearly showed the effect of the expansion of cropland, the displacement of planted areas of N-fertilizes crops by competing soybean cultivation and the relocation and intensification of beef cattle production. This new inventory constitutes a tool for policies concerning the impact of agricultural activities on air quality and contributes with more

“…Manure in animal feedlots is considered an important source of atmospheric nitrous oxide (N 2 O), methane (CH 4 ), and ammonia (NH 3 ) (Hutchinson, Mosier, and Andre 1982;Kaharabata, Schuepp, and Desjardins 2000;Lin, Liao, and Yang et al 2015;Miller and Berry 2005;Vermoesen, Cleemput, and Hofman 1997;Yang, Liao, and Wang et al 2016;Zhu, Ma, and Gao et al 2014), and the nitrogen losses in terms of N 2 O and NH 3 emissions from feedlot manure account for approximately 2.0% and 20% of the total N excretion, respectively, whereas CH 4 emissions from animal feedlots account for 1.0-2.0% of the maximum CH 4 production of manure (Intergovernmental Panel on Climate Change [IPCC] 2006).…”
