Swine producers are supplementing animal diets with increased levels of dried distillers grains with solubles (DDGS) to offset the cost of a standard corn-soybean meal (CSBM) diet. However, the environmental impact of these diets on emissions of greenhouse gases, ammonia (NH), and hydrogen sulfide (HS) is largely unknown. Twenty-four pigs (103.6 kg initial body weight) were fed a standard CSBM diet or a CSBM diet containing 35% DDGS for 42 d. Pigs were fed and their manure was collected twice daily over the 42-d trial. Pigs fed diets containing DDGS had reduced manure pH ( < 0.01), increased surface crust coverage ( < 0.01), increased manure dry matter content ( < 0.01), and increased manure C ( < 0.01), N ( < 0.01), and S ( < 0.01) contents. Animals fed DDGS diets also had significantly higher concentrations of total ammoniacal nitrogen ( < 0.01) and sulfide ( < 0.01) in their manure compared with animals fed CSBM diets. Manure emissions of NH ( < 0.01) and HS ( < 0.05) were significantly higher in animals fed the CSBM diet. There was no dietary treatment effect for methane or nitrous oxide emissions from manure. This study demonstrates that diets containing DDGS can significantly affect manure composition and potentially lower emissions of NH and HS.

“…Finally, microbial populations in slurry surface crust, absent in the experiment but oft en present in practice, may convert odor compounds into nonodorous compounds. Blanes-Vidal et al (2009) found that aged straw covers reduced emissions of DMS by 81%, whereas no eff ect was found for H 2 S.…”

Sulfur Turnover and Emissions during Storage of Cattle Slurry: Effects of Acidification and Sulfur Addition

et al. 2012

Slurry acidification using sulfuric acid reduces ammonia emissions but also affects sulfur (S) cycling. Emission of sulfur is a source of malodor and reduces the sulfur fertilizer value of the slurry. We investigated the effect of sulfate and methionine amendments, alone or in combination with acidification, on sulfur transformations in slurry and emissions of volatile sulfur compounds (VSC) during storage of fresh and aged cattle slurry. When pH was lowered to 5.5 it resulted in an almost complete inhibition of sulfate reduction. There was a huge emission of hydrogen sulfide (HS) with addition of sulfate and methionine ( < 0.01). Methanethiol (MT) was emitted in treatments with addition of methionine, especially when simultaneously acidified ( < 0.01). The large HS production in the sulfate-amended slurries resulted in little accumulation of MT and dimethyl sulfide (DMS) under neutral conditions, in contrast to acidic conditions where the degradation was inhibited and both MT and DMS accumulated. Based on odor activity values, untreated slurry had little odor development from S compounds, especially the aged slurry. Acidification did not significantly increase odor contribution from any of the compounds in fresh or aged slurry. Generally, addition of a sulfate increased the contribution from HS dramatically, whereas acidification lowered the HS contribution but increased that of MT. Thus, acidification of slurry with sulfuric acid may potentially produce more odor from S compounds than untreated slurry.

“…Agriculture is a second potential source (11)(12)(13)(14)(15)(24)(25)(26). It was reported in previous studies that both NH 3 and OSC emissions are associated with livestock activities and that their concentrations were correlated (27,28). Because emission flux measurements were not possible at the time for OSCs, we chose to estimate fluxes of OSCs from agricultural activities in the SoCAB by simultaneously measuring OSC and NH 3 ambient concentrations adjacent to a cattle feedlot in Chino, California (SI Appendix, sections 1 and 2) before dawn to avoid photochemistry.…”

Sulfuric acid (H 2 SO 4 ), formed from oxidation of sulfur dioxide (SO 2 ) emitted during fossil fuel combustion, is a major precursor of new airborne particles, which have well-documented detrimental effects on health, air quality, and climate. Another precursor is methanesulfonic acid (MSA), produced simultaneously with SO 2 during the atmospheric oxidation of organosulfur compounds (OSCs), such as dimethyl sulfide. In the present work, a multidisciplinary approach is used to examine how contributions of H 2 SO 4 and MSA to particle formation will change in a large coastal urban area as anthropogenic fossil fuel emissions of SO 2 decline. The 3-dimensional University of California Irvine-California Institute of Technology airshed model is used to compare atmospheric concentrations of gas phase MSA, H 2 SO 4 , and SO 2 under current emissions of fossil fuel-associated SO 2 and a best-case futuristic scenario with zero fossil fuel sulfur emissions. Model additions include results from (i) quantum chemical calculations that clarify the previously uncertain gas phase mechanism of formation of MSA and (ii) a combination of published and experimental estimates of OSC emissions, such as those from marine, agricultural, and urban processes, which include pet waste and human breath. Results show that in the zero anthropogenic SO 2 emissions case, particle formation potential from H 2 SO 4 will drop by about two orders of magnitude compared with the current situation. However, particles will continue to be generated from the oxidation of natural and anthropogenic sources of OSCs, with contributions from MSA and H 2 SO 4 of a similar order of magnitude. This could be particularly important in agricultural areas where there are significant sources of OSCs. methanesulfonic acid | sulfuric acid | new particle formation | atmosphere | fossil fuel
