“…Approximately 90% of intensive livestock operations in the prairie region store manure in liquid form in a holding tank or lagoon [1] until it can be land-applied. Considerable amounts of methane (CH 4 ) are emitted to the atmosphere during storage [2] and, while land application of liquid swine manure provides an effective source of nutrients for crop production [3], high ammonia (NH 3 ) volatilization rates can occur following application [4][5][6]. In addition, soil-emitted nitrous oxide can also be stimulated [7].…”

ABSTRACT). On average, agronomic performance of ADSM was similar to CTSM. The APNU of N fertilizer was greater than the 3× rate but lower than the 1× rate of ADSM or CTSM. Ammonia loss from ADSM was similar to CTSM, except for much higher loss of NH 3 -N from CTSM at the 3× rate applied in the autumn (8100 g·N·ha ). The percentage of applied N lost as N 2 O gas was generally higher for treatments receiving CTSM (4.0%) compared to ADSM (1.4%). In conclusion, the findings suggest that ADSM is equal or slightly better than CTSM in terms of agronomic performance, but has lower environmental impact.

“…In Canada, the spreading of fertilizer in several Canadian provinces is a seasonal activity (the legislation authorizes slurry spreading periodically); slurry must therefore be stored for part of the year (Laguë et al 2005). For example, the legislation in the province of Quebec allows farmers to spread their manure between April 1 and October 1 of each year (Government of Quebec 2005).…”

“…During slurry storage, the anaerobic digestion of slurry in ponds produces GHG such as CH 4 and CO 2 (Laguë et al 2005). Monteny et al (2001) established that typical CH 4 production was 4.8 kg/pig/year.…”

“…[7] During manure storage, methanogenic bacteria developed under anaerobic conditions are responsible for emissions of CH 4 and other gases like hydrogen sulphide, volatile organic compounds and CO 2 . [8,9] In Quebec, manure storage is a generalized practice because provincial laws forbid land spreading during specific periods of the year. [10] Depending on storage conditions, CH 4 concentrations emitted from covered liquid manure storage vary between 0.1 to 20 g m −3 (0.015 to 3% v/v) [11] while it takes CH 4 concentrations of between 5 and 15% (v/v) to maintain a flame for CH 4 thermal oxidation.…”

An evaluation of the effect of ammonium on the performance of two up-flow inorganic packed bed biofilters treating methane was conducted. The air flow rate was set to 3.0 L min(-1) for an empty bed residence time of 6.0 min. The biofilter was fed with a methane concentration of 0.30% (v/v). The ammonium concentration in the nutrient solution was increased by small increments (from 0.01 to 0.025 gN-NH(4) (+) L(-1)) for one biofilter and by large increments of 0.05 gN-NH(4) (+) L(-1) in the other biofilter. The total concentration of nitrogen was kept constant at 0.5 gN-NH(4) (+) L(-1) throughout the experiment by balancing ammonium with nitrate. For both biofilters, the methane elimination capacity, carbon dioxide production, nitrogen bed retention and biomass content decreased with the ammonium concentration in the nutrient solution. The biofilter with smaller ammonium increments featured a higher elimination capacity and carbon dioxide production rate, which varied from 4.9 to 14.3 g m(-3) h(-1) and from 11.5 to 30 g m(-3) h(-1), respectively. Denitrification was observed as some values of the nitrate production rate were negative for ammonium concentrations below 0.2 gN-NH(4) (+) L(-1). A Michalelis-Menten-type model fitted the ammonium elimination rate and the nitrate production rate.
