Abstract Mitigating ammonia (NH 3 ) volatilization from intensive pasture systems is critical for environmental sustainability. However, field-scale evaluation on the potential of enhanced efficiency fertilizers (e.g. urease inhibitors and controlled-release fertilizers) in mitigating NH 3 volatilization is limited. Using a micrometeorological technique, we conducted two field trials to investigate the effects of Green UreaNV ® (urea coated with the urease inhibitor N -( n -butyl)thiophosphoric ...

Abstract Urease and nitrification inhibitors are designed to mitigate ammonia (NH3) volatilization and nitrous oxide (N2O) emission, but uncertainties on the agronomic and economic benefits of these inhibitors prevent their widespread adoption in pasture systems, particularly in subtropical regions where no such information is available. Here we report a field experiment that was conducted in a subtropical pasture in Queensland, Australia to examine whether the use of the urease inhibitor N-(n-b...

Abstract Cattle feedlots are significant ammonia (NH3) emission sources, and cause high NH3 deposition. This study was conducted to investigate the responses of soil mineral nitrogen (N), percent cover of plant species, leaf N content, and leaf δ15N to NH3 deposition around a 17,500-head cattle feedlot in Victoria, Australia. Soil samples were collected in May 2015 at 100-m intervals along eight downwind transects, and plant samples were collected in June 2015 from five sites at 50- to 300-m int...

Abstract Nitrification inhibitors are effective in decreasing direct nitrous oxide (N2O) emission from agricultural soils but may stimulate ammonia (NH3) volatilization. Part of the NH3 deposited to land is converted to N2O and emitted to the atmosphere, termed indirect N2O emission. While vegetable production systems entail a considerable risk of NH3 and N2O loss from high nitrogen (N) input to the soil, the simultaneous effects of nitrification inhibitors on these N loss pathways have rarely b...

Nitrification inhibitors show promise in decreasing nitrous oxide (N2O) emission from agricultural systems worldwide, but they may be much less effective than previously thought when both direct and indirect emissions are taken into account. Whilst nitrification inhibitors are effective at decreasing direct N2O emission and nitrate (NO3–) leaching, limited studies suggest that they may increase ammonia (NH3) volatilization and, subsequently, indirect N2O emission. These dual effects are typicall...

Ammonia (NH3) volatilization is a major pathway of nitrogen (N) loss in agricultural systems worldwide, and is conducive to low fertilizer N use efficiency, environmental and health issues, and indirect nitrous oxide emission. While mitigating NH3 volatilization is urgently needed, a quantitative synthesis is lacking to evaluate the effectiveness of mitigation strategies for NH3 volatilization from synthetic fertilizers applied in agricultural systems. To fill this knowledge gap, we conducted a ...

Abstract Beef cattle feedlots are a major source of ammonia (NH 3 ) emissions from livestock industries. We investigated the effects of lignite surface applications on NH 3 and nitrous oxide (N 2 O) emissions from beef cattle feedlot pens. Two rates of lignite, 3 and 6 kg m − 2 , were tested in the treatment pen. No lignite was applied in the control pen. Twenty-four Black Angus steers were fed identical commercial rations in each pen. We measured NH 3 and N 2 O concentrations continuously from ...

Concerns about increasing concentrations of greenhouse gases in the atmosphere, primarily carbon dioxide (CO2), have raised worldwide interest in the potential of agricultural soils to be carbon (C) sinks. In Australia, studies that have quantified the effects of improved management practices in croplands on soil C have generally been inconclusive and contradictory for different soil depths and durations of the management changes. We therefore quantitatively synthesised the results of Australian...
