“…Van Weelden et al (2015) reported an average value of 121 ±86 mL CH 4 g -1 VS for both foaming and non-foaming samples, with foaming samples showing a slightly lower average value; in our study, BMP values of 155 to 395 mL CH 4 g -1 VS were found. The current BMP results were comparable to other studies, which showed that fresh swine manure ranged between 244 to 480 mL CH 4 g -1 VS (Burton and Turner, 2003;Møller et al, 2004;King et al, 2011) depending on ration. This indicates that, in our study, due to the short duration of the feeding trials and the fact that the manure storages started completely clean, (i.e., no inoculation), little decomposition of the manure organics occurred during storage based on the low reduction in methane production potential.…”

Diet ingredients are thought to contribute to foaming problems associated with swine manure stored in deeppit systems. Two experiments explored the impact of protein and carbohydrate sources and levels in swine diets on the physicochemical properties, methane production potential, and foaming potential of swine manure. The first experiment was specific to protein and evaluated the impact of dietary protein level and source on manure properties, while the second experiment focused on evaluating the impact of different dietary carbohydrate sources on manure foaming properties. Manure from the animals was tested for total and volatile solids, methane production rate and biochemical methane potential, surface tension, foaming capacity and stability, and microbial community structure. No single diet yielded manure with all of the anticipated qualities associated with foaming manure. However, manure collected from pigs fed diets containing soy hulls and distillers dried grains with solubles (DDGS) exhibited higher methane production rates (0.95 Â±0.20 and 0.96 Â±0.20 L CH 4 kg -1 VS, respectively) and biochemical methane potential (322 Â±25 and 269 Â±22 mL CH 4 g -1 VS, respectively) when compared to manure obtained from pigs fed the other diets. Additionally, the results showed that both protein level and source exhibited greater influence over the microbial community than carbohydrate source, with manipulations in the protein diet leading to positive correlations with specific microbial community and higher methane production rates, foaming capacity, and foam stability. In this study, these parameters appeared to be tied to higher levels of corn, or corn protein, in the diet. Although some of the microbial community was explained by diet, this study also demonstrated that factors other than diet have significant influence on microbial community.

“…Produced by hogs fed a standard corn and soybean ration, these two manures were considered comparable in terms of solids and nutrients [21]. All manure samples were collected in March 2010 using a sludge-judge apparatus to obtain a composite sample representing the average of depths and locations within the tanks [1].…”

“…Using (1), N available was calculated for the two experimental manures, assuming three possible cases selected to illustrate a full range of situations: Case 1 pertained to an immediate incorporation of the manure into a clay soil supporting row crops, in the spring; Case 2 pertained to the incorporation within 48 hours of the manure into a sandy loam soil in row crops, during the early summer; Case 3 pertained to manure left at the surface of a sandy loam soil supporting a hayfield, in the autumn. In all cases and for simplicity, no manure was presumed previously applied to the fields, thus CP = 1.…”

“…In-storage psychrophilic anaerobic digestion (ISPAD) occurs in manure storage tanks with an air-tight cover when its anaerobic microbial community acclimates to ambient conditions [1]. Developed for livestock operations in temperate climatic zones, ISPAD can release 65% of the manure's potential methane while lowering volatile solids by 24% [1].…”

“…Developed for livestock operations in temperate climatic zones, ISPAD can release 65% of the manure's potential methane while lowering volatile solids by 24% [1]. As opposed to mesophilic, psychrophilic anaerobic digestion limits biogas ammonia (NH 3 ) levels, despite the breakdown of proteins [2,3].…”

Swine manure subjected to In-Storage Psychrophilic Anaerobic Digestion (ISPAD) undergoes protein degradation but limited NH 3 volatilization, producing an effluent rich in plant-available N susceptible to more volatilization during land application. This study therefore measured NH 3 volatilization from both ISPAD and open tank (OT) swine manures when applied to 5 different soils (washed sand, Ste Rosalie clay, Upland sandy loam, St Bernard loam and Ormstown silt) within laboratory wind tunnel simulations. After 47 h, the NH 3 volatilized varied with both manure and soil type. For all soils, the ISPAD manure lost less NH 3 compared to OT manure, averaging 46% less. The lower solids content and higher buffering capacity of the ISPAD manure explain the advantage. The Ormstown loam maintained the same NH 3 volatilization rate after 47 h because of higher capillary effect and the St Bernard sandy loam lost the same N mass for both manures, because of a higher pH and buffer pH, with an intermediate CEC resulting in more soil solution NH 3 . Within each manure type, % TAN volatilized was highest for washed sand and lowest for the clay soil. Thus, ISPAD manure can offer up to 21% more plant-available N especially when not soil incorporated following its application.
