Abstract

This project will investigate the contribution of nitrifier denitrification to N20 and N2 emissions from agricultural soils and the impact of environmental factors and the diversity and community structure of ammonia oxidiser populations on these emissions. This will be achieved using a cross disciplinary approach in which stable isotopes and inhibition techniques will be used to determine the contribution of nitrifier denitrification to N20 and N2 emissions. Molecular techniques will be used to investigate changes in diversity of ammonia oxidisers, gene expression and functional gene diversity, and physiological studies will be made on pure and enriched cultures of ammonia oxidisers. Knowledge of this process and ammonia oxidisers responsible will increase our ability to predict N20 emissions and to develop appropriate mitigation strategies.
