Abstract

Terrestrial ecosystems are a major source of nitrous oxide (N2O), with soils accounting for ~70% of the atmospheric loading of this greenhouse gas. Here we provide a synthesis of current understanding of the environmental regulation of N2O production and reduction through different microbial pathways, presenting examples of where measured emissions have been related to characterizations of the underpinning microbial communities. We explore the direct and indirect influence of plants on rhizosphere N2O production, reduction and net emission, and the interactions between N2O production and methane oxidation, as examples of coupling between the C and N cycles that need to be considered when developing appropriate and more targeted strategies for greenhouse gas mitigation read more ...
