Closing the global N2O budget: nitrous oxide emissions through the agricultural nitrogen cycle
In 1995 a working group was assembled at the request of OECD/IPCC/IEA to revise the methodology for N2O from agriculture for the National Greenhouse Gas Inventories Methodology. The basics of the
N 2 O release from agro-biofuel production negates global warming reduction by replacing fossil fuels
The relationship, on a global basis, between the amount of N fixed by chemical, biological or atmospheric processes entering the terrestrial biosphere, and the total emission of nitrous oxide (N2O),
Methane and nitrous oxide fluxes in native, fertilized and cultivated grasslands
METHANE and nitrous oxide are long-lived, radiatively active trace gases that account for ∼20% of the total anticipated atmospheric warming1. The atmospheric concentrations of both gases have
Net global warming potential and greenhouse gas intensity in irrigated cropping systems in northeastern Colorado.
Both estimates of GWP and GHGI indicate that when appropriate crop production levels are achieved, net CO2 emissions are reduced and the results suggest that economic viability and environmental conservation can be achieved by minimizing tillage and utilizing appropriate levels of fertilizer.
The potential to mitigate global warming with no‐tillage management is only realized when practised in the long term
No‐tillage (NT) management has been promoted as a practice capable of offsetting greenhouse gas (GHG) emissions because of its ability to sequester carbon in soils. However, true mitigation is only
CO2, CH4 and N2O flux through a Wyoming snowpack and implications for global budgets
INCREASING atmospheric concentrations of the three main greenhouse gases—carbon dioxide, methane, and nitrous oxide— account for about 70% of anticipated global warming1, but the
Closing the global N2O budget: A retrospective analysis 1500–1994
We present new estimates of global nitrous oxide (N2O) emissions for the period 1500–1994 based on revised Intergovernmental Panel on Climate Change guidelines [Intergovernmental Panel on Climate
Generalized model for N2 and N2O production from nitrification and denitrification
We describe a model of N2 and N2O gas fluxes from nitrification and denitrification. The model was developed using laboratory denitrification gas flux data and field-observed N2O gas fluxes from
Generalized model for NOx and N2O emissions from soils
We describe a submodel to simulate NOx and N2O emissions from soils and present comparisons of simulated NOx and N2O fluxes from the DAYCENT ecosystem model with observations from different soils.
