Title
New emission factors for nitrous oxide from crop residues – N2OResidue

Research area and project description
Nitrous oxide (N2O) is an important greenhouse gas, and agriculturals soils are responsible for the majority of N2O emissions. A large share of these N2O emissions is due to the crop residues that are left in the field, due to release of nitrogen after mineralization. The IPCC are developing methods to estimate emission factors for these emissions which are eventually used for national greenhouse gas accounting. However, the current IPCC methodology for accounting N2O emissions from crop residues is very simplistic, resulting in misguided assessments of mitigation measures and their potentials.

The overall aim of the project N2OResidue is therefore to develop and document a new improved methodology for operational accounting of N2O emissions from crop residues at farm and national scales.

The specific objectives are:

• To develop and validate new and improved emission factors for N2O emissions from crop residues depending on type and management.
• To develop national values for biomass amounts and nitrogen concentrations in crop residues for relevant residue types.
• To devise and test methods for implementation of new residue emission factors and residue nitrogen amounts for various crops and cover crops at farm and national scales.

The PhD project will support these goals by estimating emissions in field experiments with a variety of crop residues and soil types. Fluxes in the field will be quantified using flux chambers coupled with a laser-based sensor. Additional measurements will include quantification soil nutrients and plant biomass. The mechanisms behind the processes leading to N2O emissions under field conditions will be investigated in laboratory experiments.
The future PhD student will be working in close collaboration with another PhD student at the University of Copenhaguen, who will be be conducting related field trails.
