Unravelling the microbial mechanisms of soil nitrous oxide emissions
Grant number: DE150100870 | Funding period: 2015 - 2018
Soil ecosystems are believed to be the most dominant sources of global nitrous oxide emissions. However, mitigations of nitrous oxide are strongly hindered by lack of knowledge on microbial mechanisms underpinning its production. This project aims to integrate a range of advanced approaches to identify the key nitrogen cycling genes as best predictors of nitrous oxide in field studies, to disentangle relative contribution of microbial pathways to nitrous oxide in glasshouse and microcosm studies, and to validate these findings across various land-use types in Australia and China. This will provide a critical framework incorporating microbial data into the nitrous oxide prediction models for ..View full description
