Dr Taleta Bailey’s research focuses on understanding the interactions between carbon and nitrogen cycling in soils, and using these processes to improve sustainable management of agricultural systems. Her work uses lab- to field-scale measurements of nitrogen cycling, soil organic carbon pools and greenhouse gas emissions to understand the mechanisms linking nitrogen between soil organic matter, plant-available forms and loss pathways. Her current work focuses on using 15N stable isotopes to measure denitrification losses of nitrous oxide (N2O) and di-nitrogen (N2) gases from soil, contributing to the greenhouse gas emissions and efficiency of nitrogen fertiliser use.
The ultimate aim of her work is to understand the processes that control the availability of nitrogen in agricultural systems, the factors that affect these processes and how they can be leveraged to improve nitrogen management. This foundational knowledge builds towards reducing the environmental footprint of agriculture by minimising soil greenhouse gas emissions, boosting soil carbon storage, and maximising the function and productivity of soils.
