To quantify the magnitude and variability of N2O emissions associated with the application of crop residues to soils, and identify strategies to reduce emissions.

Specific objectives are to:

• Quantify the magnitude and variability of direct and indirect N2O emissions over time associated with the application of different types of crop residues

• Explore and quantify the impact by soil and climatic conditions on N2O emissions from crop residues

• Explore and quantify the impact by management factors on N2O emission peaks

• Through statistical analyses identify high-risk and low-risk conditions for N2O emissions from crop residues
