No-till only increases N2O emissions in poorly-aerated soils (2008). Soil & Tillage Res. 101: 97–100. Philippe Rochette, AAFC, Québec City, QC, Canada G1V 2J3. Denitrification rates are often greater in no-till than in tilled soils and net soil-surface ghg emissions could be increased by enhanced soil N2O emissions following adoption of no-till. Results suggest that the impact of no-till on N2O emissions is small in well-aerated soils but most often positive in soils where aeration is reduced by conditions or properties restricting drainage.
Nitrous Oxide Emissions Respond Differently to No-Till in a Loam and a Heavy Clay Soil (2008). Philippe Rochette, Denis A. Angers, Martin H. Chantigny, Normand Bertrand - Agriculture and Agri-Food Canada, Québec City, QC, Canada, G1V2J3. Soil Sci Soc Am J 72:1363-1369 (2008). Annual emissions of N2O were exceptionally high in the heavy clay soil, varying from 12 to 45 kg N2O-N ha–1 during the 3 yr of the study. Such high emissions were probably not associated with fertilizer N inputs but rather with denitrification sustained by the decomposition of large soil organic matter stocks (192 Mg C ha–1 in the top 0.5 m). On average, NT more than doubled N2O emissions compared with MP in the heavy clay soil.

Nitrous Oxide Flux from Solid Dairy Manure in Storage as Affected by Water Content and Redox Potential. J Env. Qual 29:630-638 (2000) [pdf]. H. A. Brown, C. Wagner-Riddle & G. W. Thurtell, U. of Guelph, Guelph, ON, Canada. Study conducted on solid dairy manure to determine potential for N2O emission during storage. A lab flow-through chamber & tunable diode laser analyzer were employed to continuously quantify the N2O flux in a temp.-controlled environment. Water, NO3-N and NH4-N contents and redox potential were monitored. Experiment 1: manure samples collected from 3 layers near the surface of the pile & incubated at 22°C for 20 d. Mean daily N2O-N fluxes - 0 & 0.33 g N m–2 d–1, and N2O was only generated in samples from the top two layers of the pile. Experiment 2: samples from the 30- to 45-cm depth were adjusted by amendment with chopped straw to 70, 75, and 80% water content (WC). These samples showed less variable fluxes and produced 2x N2O-N as the unamended samples. Levels of straw-amendment had no significant effect on N2O emissions. Combined results - fluxes were highest at 55 to 70% WC and 150 to 250 mV Eh. N2O emission was limited by low NO3-N levels in samples with high WC and low Eh. Increasing WC and decreasing Eh with depth and increasing levels of NO3 in the surface layer over time revealed that the exterior of solid manure piles is crucial to the flux of N2O.

The Health of our Air (1999) [3259 KB pdf]. Agriculture and Agri-Food Canada. Of the N consumed by livestock in feed, as much as 78% is excreted in urine and feces. In 1 year, for example, a dairy cow may excrete as much as 100 kg N or more. Consequently, animal manure contains large amounts of N; in Canada, the N excreted each year by livestock may approach the amount of N applied as fertilizer......The amount of N2O emitted from manured soils depends on method and rate of application, type of manure, and soil properties. One study suggests that liquid manure applied in bands may produce more N2O than manure applied uniformly on the soil surface.
Estimates of Emissions: Reducing nitrous oxide emissions. (1999). The Health of our Air [3259 KB pdf]. Agriculture and Agri-Food Canada; Much of the N2O emitted from farmland is produced when excess NO3 in soil undergoes denitrification, either on farmland or after it is leached away. Farmers can reduce these emissions by preventing build-up of NO3 or avoiding soil conditions that favour denitrification. Some N2O is also emitted when NH4 is converted to NO3 (nitrification). Adding less NH4 or slowing the rate of nitrification can reduce emissions from this source.

Region-specific assessment of greenhouse gas mitigation with different manure management strategies in four agroecological zones. (2009) (abstract). Global Change Biology. Sven Sommer et al., U. of Southern Denmark. Livestock farming systems are major sources of trace gases contributing to emissions of the greenhouse gases (GHG), N2O and CH4, i.e. N2O accounts for 10% and CH4 for 30% of the anthropogenic contributions to net global warming. This paper presents scenario assessments of whole-system effects of technologies for reducing GHG emissions from livestock model farms using slurry-based manure management. Results demonstrated that changes in manure management can induce significant changes in CH4 and N2O emissions and carbon sequestration, and that the effect of introducing environmental technologies may vary significantly with livestock farming practice and interact with climatic conditions. Shortening the in-house manure storage time reduced GHG emissions by 0–40%. The largest GHG reductions of 49 to, in one case, 82% were obtained with a combination of slurry separation and incineration, the latter process contributing to a positive GHG balance of the system by substituting fossil fuels......

Agricultural Influences on Carbon Emissions and Sequestration: A Review of Evidence and the Emerging Trading Options (Mar. 2001) (82 KB pdf). Jules Pretty and Andrew Ball, Centre for Environ. & Society, and Dept of Biol. Sci., University of Essex, UK (Occasional Paper 2001-03). At current prices, it is clear that farmers are not set to become solely carbon farmers. However, systems accumulating carbon are also delivering many other public goods, such as improved biodiversity and clean water from watersheds, and policy makers may also seek to price these so as to increase the total payment package. Carbon, therefore, represents an important new source of income for farmers, as well as helping to encourage farmers to adopt a wide range of sustainable practices.
Economic Evaluation of Emission Reductions of Nitrous Oxides and Methane in Agriculture in the EU [344 KB pdf] (Feb 2001).

Growing Carbon: A New Crop That Helps Agricultural Producers and the Climate Too. [PDF] USDA/NRCS. Everyone talks about the weather, but no one does anything about it. This old saying may no longer be quite true. While day-to-day weather is hard to predict, more and more evidence suggests that human activities are beginning to change the overall climate of our planet, in ways that may hurt agricultural producers.

Moore, USDA/ARS Poultry Products Res. - FAX: (501)575-7465; Email: email@example.com; Alum applications to poultry manure reduce the amount of water pollution caused when land is fertilized with this resource. The objectives of this study were to see how alum affects ammonia emissions in poultry houses and, in turn, it's effect on poultry growth. Another objective was to determine how alum applications would affect phosphorus runoff (pollution) from fields fertilized with poultry litter. The results showed that alum greatly reduced ammonia emissions, causing the chickens to grow better. When the litter was applied to pastures, phosphorus runoff was reduced by 73%, compared to normal litter. This study indicates that adding alum to chicken litter will result in improved poultry performance, while reducing pollution.

Agriculture Sector Analysis on Greenhouse Gas Emission Mitigation in the United States [919 KB pdf]. Ph.D. Dissertation by Uwe Andreas Schneider, Agricultural Economics, Texas A&M University, Dec. 2000. This dissertation analyzes the economic potential of agriculture to participate in greenhouse gas emission mitigation efforts. Major agricultural mitigation strategies are included simultaneously to capture interactions. Results indicate that agriculture's contribution to emission reduction may be substantial, but not sufficient to fulfill the requirements of the Kyoto Protocol, which are estimated to be in the neighborhood of 700 million metric tons (MMT) of carbon equivalents by the year 2010.
Estimating Agricultural Nitrous Oxide Emissions (2008) Stephen J. Del Grosso et al. Trans. Amer. Geophys. Union 89(51): 529. Emissions of nitrous oxide (N2O), a potent greenhouse gas, tend to be underestimated by standard methods of quantification provided by the Intergovernmental Panel on Climate Change (IPCC) [IPCC, 2006]. Soil water content, temperature, texture, and carbon availability influence N2O emissions, but the strongest correlate is usually N inputs to the system, especially at large scales [Stehfest and Bouwman, 2006].

CH4 AND N2O EMISSIONS FROM LIVESTOCK MANURE [261 KB pdf]. Paul Jun, Michael Gibbs, and Kathryn Gaffney (ICF Incorporated). - Methane estimates - livestock population data characterized by subgroup are required. For Tier 1 estimates, necessary population data should be readily obtainable within the country or from the Food and Agricultural Organization (FAO). The Tier 2 estimates require additional data on manure characteristics and manure management practices, for which country-specific data should be used. These data should be obtained through data collection activities. If necessary, IPCC default values can be used for some of the factors in the Tier 2 calculation. ( methodology + emission factors included).

Greenhouse gas emissions from stored liquid swine manure in a cold
40(4), Feb. 2006, P. 618-627. K-H Park, A.G. Thompson, M. Marinier, K. Clark & C. Wagner-Riddle, U. of Guelph, ON. A 4-tower micromet. mass balance method was used at 3 swine farms in Ontario, Canada (annual Tair <10 °C), from July 2000 - May 2002. Methane and N2O concentrations were measured using 2 tunable diode laser trace gas analyzers, and manure temperature (Tman), redox potential (Eh) and composition were also measured. Our data suggests that N2O emissions from non-aerated liquid swine manure storage could be ignored in GHG inventories. The methane conversion factor derived from measured fluxes was 0.23, comparable to the USEPA derived values of 0.22–0.25, but much lower than the IPCC recommended value for cold climates (0.39).

Nitrogen Oxide and Methane Emissions under Varying Tillage and Fertilizer Management (2005) [pdf]. J Env. Qual 34:1467-1477. Rodney T. Venterea (USDA-ARS, St. Paul, MN 55108); Martin Burgera (U. Minn., St. Paul), and Kurt A. Spokas (USDA-ARS, Morris, MN 56267) - Comprehensive assessment of the total greenhouse gas (GHG) budget of reduced tillage agricultural systems must consider emissions of nitrous oxide (N2O) and methane (CH4), each of which have higher global warming potentials than carbon dioxide (CO2). Tillage intensity may also impact nitric oxide (NO) emissions, which can have various environmental and agronomic impacts; study demonstrates that N2O emissions can represent a substantial component of the total GHG budget of reduced tillage systems, and that interactions between fertilizer and tillage practices can be important in controlling non-CO2 GHG emissions.
Biological degradation and greenhouse gas emissions during pre-storage of liquid animal manure (2004). Moller HB, Sommer SG, & Ahring BK; Danish Inst. of Agric. Sci., Dept of Agric. Eng., Res.

Three applications of swine effluent were applied to soybean and gaseous fluxes were determined from gas concentration profiles and the flux-gradient gas transport technique. The large losses of NH3 and N2O illustrate the difficulty of basing effluent irrigation schedules on N concentrations and that NH3 emissions can significantly contribute to N enrichment of the environment.
Reducing Greenhouse gas emissions from Livestock Agriculture in Manitoba (May 2001) [26 KB pdf]. Karin Wittenberg and Dinah Boadi, Dept of Animal Sci., U. of Manitoba, Winnipeg, Manitoba. For MANITOBA CLIMATE CHANGE TASK FORCE, Public Consultation Sessions. There is a great deal of uncertainty associated with emissions from the manure management systems, including loss of N associated with different handling systems, storage and application and therefore reduction strategies cannot be effective assessed. More research into the various sectors of the manure management system should be encouraged by the Manitoba government. This is particularly important given the active development of regulation regarding manure storage and application by the province and individual municipalities.
Regulation of Nitrous Oxide Emissions from Soils Irrigated with Dairy Farm Effluent (2001). L. Barton and L.A. Schipper, Landcare Research, Private Bag 3127, Hamilton, New Zealand. In J. Env.

Greenhouse Gas Emissions from Composting of Agricultural Wastes. Alberta Agriculture & Rural Development - Composting is an alternative to conventional management of agricultural wastes. It produces a recycled product, which is carbon rich, free of most pathogens and weed seeds, and enhances soil quality. Studies suggest that aerobic composting systems emit less total GHG (CO2-E) than anaerobic composting systems. However, further research is needed to quantify the amount of GHG emitted from the composting process [ PDF version - 690 KB] [Feb. 2001].
Gaseous NO, NO2, and NH3 Loss during Cattle Feedlot Manure Composting [104 KB pdf]. Xiying Hao* and Chi Chang, Lethbridge Res. Centre, AAFC; In "Internet-Conference "Nitrogen Emissions from Soil", Sept 18th - Dec 31, 2000. Atmospheric concentrations of NH3, NO and NO2 at the windrow surface and 50 cm above were monitored throughout the composting period (99 days). Composting increased the atmospheric concentration of NH3 and NO, while NO2 was not affected. Since the decomposition of manure/compost materials was incomplete for the passive aeration treatment, further studies are needed to investigate possible techniques to reduce NH3 and NO losses (retaining more N in the finishing compost) while increasing the composting rate.
