“…This is similar to the findings of Gordon et al (2000), who reported no difference in NH 3 volatilization when using the Aerway equipment for incorporation vs. surface application. However, in the study by Gordon et al (2000), the Aerway was used either before slurry application or after, whereas in the present study the manure was applied immediately before the tines of the Aerway system. Contrary to the present findings, Bittman et al (2005) reported a 48% reduction in NH 3 emissions with Aerway incorporation vs. surface application of liquid dairy manure.…”

“…Phillips et al (1990) reported large losses of NH 3 (and production of odour) when slurry was sprayed into air, which was significantly reduced by soil injection or using hanging/trailing hoses. Gordon et al (2000) reported only a small benefit of soil aeration (in pasture) on reducing NH 3 loss, but found aeration also reduced grass yield. In their study, an aerator was used that created slots 1.5 cm wide, 15 cm long and 15 to 20 cm deep.…”

McGinn, S. M. and Sommer, S. G. 2007. Ammonia emissions from land-applied beef cattle manure. Can. J. Soil Sci. 87: [345][346][347][348][349][350][351][352] ) is emitted in vast quantities from exposed livestock manure. The volatilisation of NH 3 from livestock manure is a loss in valuable nitrogen in land-applied manure that could otherwise be used for crop production. Ammonia loss to air is also affiliated with environmental problems when it is deposited to the surrounding landscape. The goal of this study was to quantify the effect of managing beef cattle manure on NH 3 emissions of land-applied manure. Three trials were conducted where beef feedlot manure was applied. The NH 3 losses were measured from field plots (90 or 160 m 2 ) using acid traps (passive flux samplers). Immediately after applying manure, irrigating with 6 mm of water reduced NH 3 loss by 21-52% while tillage (to 15 cm depth) reduced the loss by 76-85% compared with leaving the manure spread on the soil surface. Piled manure that was applied to the land lost 27% less NH 3 than did manure taken directly from the pen. There was little NH 3 lost from compost that was applied to land since the applied available-N was very low relative to the pen and piled manure. Our study shows that management of livestock manure has a direct impact on NH 3 loss to air. It follows that significant reduction in NH 3 volatilisation can benefit agriculture and reduce agriculture's impact on the environment. . La sublimation du NH 3 présent dans le fumier épandu sur les terres entraîne la perte d'un azote précieux pour les productions végétales. Le passage de l'ammoniac dans l'air suscite aussi des problèmes environnementaux quand le gaz se dépose sur le relief environnant. L'étude devait quantifier l'incidence des pratiques de gestion sur les émissions de NH 3 après épandage du fumier. Pour cela, les auteurs ont effectué trois expériences durant lesquelles ils ont épandu du fumier de bovins. Ils ont mesuré les pertes de NH 3 sur des parcelles de 90 ou 160 m 2 au moyen de capteurs d'acide (échantillonneurs passifs de flux). L'irrigation de 6 mm d'eau immédiate-ment après l'épandage réduit les pertes de NH 3 de 21 à 52 % alors que le travail du sol (15 cm de profondeur) les diminue de 76 à 85 %, comparativement à ce qu'on observe quand on laisse le fumier à la surface du sol. Le fumier gardé en tas perd 27 % moins de NH 3 que celui prélevé directement des enclos au moment de l'épandage. Le compost répandu sur le sol perd peu de NH 3 car il contient très peu de N disponible comparativement au fumier venant des enclos ou d'un tas. L'étude indique que la méthode de gestion a une incidence directe sur les pertes de NH 3 dans l'air. Il s'ensuit qu'une diminution sensible de la sublimation du NH 3 présenterait un avantage certain pour l'agriculture tout en atténuant l'impact des pratiques agricoles sur l'environnement.

“…Some nutrients, particularly N, however, may be lost to the atmosphere after land application; thereby reducing the value of the manure and contributing to environmental degradation (Gordon et al 2000). Up to 90% of applied ammoniumnitrogen (NH 4 ' -N) in manure can be lost through ammonia (NH 3 ) volatilization (Wulf et al 2002).…”

. 2008. Management strategies to simultaneously reduce ammonia, nitrous oxide and odour emissions from surface-applied swine manure. Can. J. Soil Sci. 88: 571Á584. Surface-applied swine manure has the potential to generate ammonia (NH 3 ), nitrous oxide (N 2 O) and odour. Field research was conducted in Prince Edward Island to measure the simultaneous emissions of NH 3 , N 2 O and odour following the surface-application of swine manure. Manure was applied to a grain stubble field consisting of a sandy loam soil low in pH (5.6Á5.9). The effect of manure type (liquid and solid), application rate [conventional/typical rate (1)): 30 000Á36 000 L ha(1 , double (2)): 60 000Á72 000 L ha(1 and five times (5)): 180 000 L ha(1 ] and rainfall (8Á200 mm) before and after liquid manure application were examined. There was no relationship between odour emissions and manure type, application rate and rainfall before and after spreading, due to high variability. Liquid manure (dry matter (DM 045 g kg(1 ) reduced NH 3 emissions by 32% compared with solid (DM 0350 g kg (1 ). Increasing application rates enhanced NH 3 emissions; increasing the rate by 2 )and 5)the typical rate increased losses by 62 and 78%, respectively. Applying manure prior to rainfall reduced NH 3 emissions by 37%, compared with application after a rainfall. Ammonia and odour emissions were similarly correlated to atmospheric conditions with increased emissions at higher air and soil temperature, net radiation, vapour pressure deficit and windspeed. Nitrous oxide emissions were low in magnitude and showed no correlation to climatic conditions, suggesting that management strategies to reduce both odour and NH 3 did not enhance N 2 O emissions when applied to a moderately acidic soil with low levels of soil nitrate (B5 mg N kg (1 ). Our results indicate that for conditions similar to those in this study, there is no trade-off between NH 3 and N 2 O production and more attention should be placed on controlling and reducing odour and NH 3 emissions.
