Contribution of comammox bacteria to soil nitrification. This project aims to understand the diversity, activity and environmental relevance of comammox bacteria, the newly-discovered complete nitrifiers, in Australian soils, and to evaluate their relative contributions to nitrification processes compared to other canonical nitrifying prokaryotes. Nitrogen transformations are pivotal microbial processes, with nitrification largely responsible for nitrogen losses through nitrous oxide emissions a ....Contribution of comammox bacteria to soil nitrification. This project aims to understand the diversity, activity and environmental relevance of comammox bacteria, the newly-discovered complete nitrifiers, in Australian soils, and to evaluate their relative contributions to nitrification processes compared to other canonical nitrifying prokaryotes. Nitrogen transformations are pivotal microbial processes, with nitrification largely responsible for nitrogen losses through nitrous oxide emissions and nitrate leaching in the terrestrial ecosystems. The expected outcomes will develop new knowledge on the comammox bacteria and provide novel insights into refined strategies to manipulate nitrification processes for improved nitrogen use efficiency and sustainable agricultural management.Read moreRead less
Linking soil acidification with carbon dynamics in Australian agroecosystems. The ability to mitigate climate change by sequestering soil carbon may be limited in acidic soils, which are prevalent in Australia. The project will investigate the link between carbon cycling, soil acidification and liming, and provide important knowledge to identify agricultural practices which have the capacity to build soil carbon.
