Mitigating Nitrous Oxide Emissions Following Grassland Cultivation


This project will explore the biological basis of nitrous oxide (N2O) emissions following grassland cultivation, and potential mitigation options (shallow incorporation, manipulation of botanical composition, a novel use of the nitrification inhibitor DMPP). Simulating field-scale heterogeneity, functional genes of nitrification and denitrification, as well as microbial and earthworm community dynamics, will be studied to understand the regulation of N2O formation around decomposing residues. Promising strategies for N2O mitigation will be evaluated under field conditions.
