Intensive measurement of nitrous oxide emissions from a corn–soybean–wheat rotation under two contrasting management systems over 5 years
No-tillage (NT), a practice that has been shown to increase carbon sequestration in soils, has resulted in contradictory effects on nitrous oxide (N2O) emissions. Moreover, it is not clear howExpand

Methane and nitrous oxide emissions from Canadian animal agriculture: A review
Considerable evidence of climate change associated with emissions of greenhouse gases (GHG) has resulted in international efforts to reduce GHG emissions. The agriculture sector contributes about 8%Expand

Estimation of N2O emissions from agricultural soils in Canada. I. Development of a country-specific methodology
International initiatives such as the United Nations Framework Convention on Climate Change and the Kyoto Protocol require that countries calculate national inventories of their greenhouse gasExpand

Nitrous oxide emissions from agricultural fields during winter and spring thaw as affected by management practices
Highest rates of N2O emissions from fertilized as well as natural ecosystems have often been measured at spring thaw. But, it is not clear if management practices have an effect on winter and springExpand

Linking Nitrous Oxide Flux During Spring Thaw to Nitrate Denitrification in the Soil Profile
The importance of spring thaw nitrous oxide (N 2 O) fluxes to the total N 2 O emission budget in cold climates has been recognized recently. Two mechanisms have been proposed to explain the burst inExpand

Toward Improved Coefficients for Predicting Direct N2O Emissions from Soil in Canadian Agroecosystems
Agricultural soils emit nitrous oxide (N2O), a potent greenhouse gas. Predicting and mitigating N2O emissions is not easy. To derive national coefficients for N2O emissions from soil, we collatedExpand

Estimates of nitrous oxide emissions from agricultural fields over 28 months
Field studies conducted throughout the calendar year are needed to improve flux estimates for the greenhouse gas nitrous oxide (N2O). In this study, we report monthly N2O emissions measured usingExpand

Minimizing nitrogen losses from a corn–soybean–winter wheat rotation with best management practices
Best management practices are recommended for improving fertilizer and soil N uptake efficiency and reducing N losses to the environment. Few year-round studies quantifying the combined effect ofExpand

Potential carbon sequestration in rubber tree plantations in the northwestern region of the Paraná State, Brazil
Rubber tree plantations may improve the soil's physical and chemical properties, and they may sequester atmospheric carbon in the biomass or the soil. However, the potential role of these plantationsExpand

Greenhouse gas emissions from stored liquid swine manure in a cold climate
Abstract Current global warming has been linked to increases in greenhouse gas (GHG) concentrations. Animal manure is an important source of anthropogenic GHG, mostly of methane (CH4) and nitrousExpand
