“…When increasing temperature by 58C for each trial, NH 3 losses increased by less than 1%. Results are contrary to studies by Brunke et al (1988), Sommer and Olesen (1991) and Moal et al (1995) who found losses were significantly enhanced when air temperatures increased. Hoff et al (1981) similarly found that increases in temperature resulted in greater losses from hog manure.…”

“…Laboratory and field experiments, however, can be time consuming and expensive. Empirical models (Moal et al 1995;Menzi et al 1998;Søggard et al 2002;Misselbrook et al 2005) and various mechanistic models (Rachhpal-Singh and Nye 1986;van der Molen et al 1990;Ge´nermont and Cellier 1997;Ni 1999;Wu et al 2003), such as Volt'Air, have been developed to simulate NH 3 losses from fertilizers. Few models, however, have been validated with independent data sets from regions outside the area where they were developed.…”

M. 2009. Simulating ammonia loss from surface-applied manure. Can. J. Soil Sci. 89: 357Á367. The land spreading of manure can result in significant nitrogen (N) losses to the atmosphere through ammonia (NH 3 ) volatilization. It is estimated that agricultural activities, including manure spreading contribute approximately 50% of the total global NH 3 emissions. Computer simulation models have been developed in an attempt to predict NH 3 losses resulting from manure spreading. Few models have been validated with success and no validation has been completed for conditions found in eastern Canada. The mechanistic model Volt'Air was implemented and tested to estimate NH 3 emissions using field-based wind tunnel data from three field locations in eastern Canada. The model was validated using data from 27 wind tunnel trials, which measured NH 3 loss over 5Á19 d. Sensitivity analysis revealed that Volt'Air was most sensitive to pH. Good overall agreement was observed between measured results and model simulations over 5Á19 d (R 2 00.91, RMSE 02.9 kg ha(1 ). Short-term flux simulations (kg ha(1 h(1 ) within the first 24 h after spreading were underestimated by 29.5% and fluxes on subsequent days were slightly underestimated by 3.7%. Error with Volt'Air appears to be largely confined to the first day following manure application. Volt'Air offers potential for predicting NH 3 losses (i.e., 5Á19 d) from manure application within eastern Canada. Improving the simulation of short-term pH changes, however, may result in enhanced overall model performance.

. 2001. Ammonia volatilization and soil nitrogen dynamics following fall application of pig slurry on canola crop residue. Can. J. Soil Sci. 81: 515-523. Land application of liquid manures is a major source of atmospheric ammonia. The presence of crop residues on the soil surface usually increases emissions by retarding slurry infiltration, whereas incorporation of slurry into soil reduces emissions. Our objective was to quantify the relative reduction in NH 3 volatilization resulting from the soil incorporation of pig slurry (PS) applied on canola (Brassica napus) residues under fall conditions in Quebec, Canada. Pig slurry was applied at 7.4 L m -2 on six plots covered by canola crop residues. Slurry and residues were incorporated in the top 5 cm of soil (INCORP) in half of the plots, while the other half were left untouched (SURF). Ammonia volatilization was measured following application for 10 d using wind tunnels. Soil NH 4 + and NO 3 -contents, pH, moisture and temperature were also monitored to explain variations in NH 3 fluxes. Soil NH 4 + -N in the surface soil was lower than expected shortly after slurry application, maybe as a result of fixation by clays or interception by crop residues. The volatilization of NH 3 was higher (P < 0.05) on SURF plots than on INCORP plots in 20 of the 26 measuring periods, with total NH 3 losses being five times greater in the former. Cumulated emissions during the first 11 h accounted for the 60 and 53% of total NH 3 emissions for the SURF and INCORP plots, respectively. Our results confirm that a large fraction of the NH 3 volatilization from slurry application on canola residues can be greatly reduced if the slurry and crop residues are incorporated into the soil immediately after slurry application. Despite significant reduction (80%) of NH 3 volatilization in INCORP compared with SURF plots, no difference was found in soil mineral N between treatments, suggesting that other processes such as N mineralization or denitrification were more active in INCORP plots.

“…Indeed, according to the author, process of volatilization varies with the NH 4 + concentration in the manure, the enzyme activity, the pH, the temperature, and the slurry properties. Complementary to this author, [39] describes in fact, an equilibrium which exists between the concentrations of 4 …”

In spite of the relevance of current studies on the importance of organic fertilizers such as animal manure in improving the health of ecosystems, little is known about the biochemical mechanisms affecting the availability of nutrients released from the organic fertilizer in water. A litter bag study during 6 weeks was carried out in pots containing 25 liters of water with 15 g of pig dejections as organic fertilizers. The experimental design was a completely randomized block design with three replications. The treatments consisted of dejections of pigs nourished with: recommended diet composition T1, partially improved diet with Azolla filiculoides T2, improved diet with Azolla filiculoides T3, improved diet with cereal bran T4. A control treatment without dejection (T0) was considered in the study for comparison purpose. Four pigs per type of diet were considered leading to 16 white landrace pigs of six months age followed for dejection collections. Strong release of nutrients for better yield for agro-fish system was obtained in the manure T1 with
