“…Our finding suggests that increasing the species richness is effective to reduce NH 3 volatilization from CWs. The current NH 3 abatement methods, which are physical or chemical (Ndegwa et al, 2008;Wagner et al, 2011;VanderZaag et al, 2015), are more expensive and have a higher carbon footprint than the ecological method provided by this study. We confirm that assembling plant communities with high species richness is an alternative approach for NH 3 volatilization reduction.…”

“…While there are some abatement methods for reducing NH 3 from wastewater, such as acidification and rapid nitrification by artificial means, these methods are expensive and energy consuming, and therefore are not feasible (Lin et al, 2005;VanderZaag et al, 2015). There is still a lack of appropriate abatement methods, while alternative ecological approach like plants receives less attention.…”

Ammonia volatilization from wastewaters with a high concentration of ammonium is a serious environmental and health problem. Constructed wetlands (CWs) are widely used for treating wastewater, and plant diversity clearly improves some functions of ecosystem such as nitrogen removal. However, whether plant diversity can affect ammonia volatilization from wastewater is still unknown. In this study, we conducted a microcosm experiment with different plant diversity treatments using four plant species. Results showed that, (1) ammonia volatilization decreased with increasing plant species richness; (2) ammonia volatilization from systems containing Rumex japonicus was lower than other systems; and (3) ammonia volatilization was affected more by species composition than species richness. This paper is the first to report that ammonia volatilization is reduced by plant diversity, and that some plant species combinations are important to reduce ammonia volatilization from CWs when treating wastewater.

“…Emissions from liquid manure stores in Canada are lower than in many countries, because of low emission in winter and extensive natural crusts (Sheppard et al ., ; VanderZaag et al ., ). Emissions during tank agitation prior to spreading could be abated with synthetic covers, but the benefit is unknown and probably not large.…”

Most ammonia (NH 3 ) emissions (85%) in Canada come from agricultural sources (400 kt/yr). There are international conventions that require countries to mitigate NH 3 emissions but there are no federal or provincial guidelines in Canada stipulating emission targets or best practices for agriculture. This study examines the potential for mitigating atmospheric NH 3 using a range of approaches. Taking current farm practices into account, employing proven low-cost measures (low-emission slurry application and slurry storage covers) would reduce annual emissions from livestock operations by 16 kt NH 3 -N, while using all available low-cost measures would reduce emissions by 79 kt NH 3 -N or 26% of livestock emissions. Another 36 kt/yr could be avoided by improving fertilizer practices, so that the total potential reduction would be about 29% of all agricultural emissions. Emissions from beef cattle and pig production could be reduced by 18% if consumption was cut by 50%, with greater mitigation if production for export was reduced, although the economic and social consequences need to be considered. Mitigation practices must be viewed in the context of possible pollution swapping especially in surplus nitrogen situations. Emissions must also be considered in terms of atmospheric NH 3 transport to and from the USA, therefore bi-national agreements to jointly reduce emissions might be needed. It may be more cost-effective in Canada to strategically reduce emissions to minimize risks to health (from particulate matter) and the environment rather than to reduce annual national emission targets.

“…Emission data from such semifloating systems are currently not available. It seems likely that this cover type, which leaves a certain proportion of the store surface uncovered, differs in emission mitigation efficiency from common floating covers placed directly onto the slurry (VanderZaag et al., 2015). Especially at a low FL, the air exchange could be substantial with the semifloating system (Figure 1b).…”

A novel approach to estimate the abatement of ammonia emissions from mitigation techniques at farm‐scale slurry stores exemplified by a semifloating cover

Ammonia (NH3) losses from livestock slurry stores substantially contribute to agricultural emissions to the atmosphere. Gas release from slurry storage facilities is driven by interactions between store operations and meteorological conditions. This study quantifies the abating effect of an impermeable semifloating cover as an emission mitigation technique at a farm‐scale slurry storage tank. Emissions were measured over 1 yr and compared with the preceding 2 yr of measurements with the uncovered tank. In this novel approach, emission data were aggregated to categories within 1 h measuring intervals according to five key factors influencing emissions (time span after agitation and tank‐filling level as surrogates for natural crust occurrence; the meteorological parameters precipitation, air temperature, and wind speed) for the two consecutive measurement campaigns with and without the cover. The emission abatement effect of the cover was determined by emission modeling of the entire measuring campaign based on measuring intervals of the uncovered and the covered tank where the aggregated categories of influencing factors were equal. The resulting average emission abatement was 48%. An average abatement of 37 and 54% was achieved during periods with and without a surface crust, respectively. The emission reduction was less with low tank filling level due to higher air exchange through openings of the cover. The presented approach is applicable to evaluate emission mitigation techniques for single farm‐scale stores. With adequate measurement duration, it is appropriate to produce reliable emission data reflecting the complex interactions between emissions and influencing factors occurring at real‐world storage facilities.
