The Agricultural Greenhouse Gas group investigates how agricultural management influences greenhouse gas emissions, ammonia loss and soil nitrogen processes across diverse production systems.
Our work integrates field-scale measurement, process-based modelling and mitigation research to generate robust evidence for industry, policy and sustainable farm management. Our research spans dairy, grain, vegetable, sugarcane and intensive livestock systems.
Our capabilities include
Field-scale measurement of greenhouse gas and ammonia emissions
We apply advanced approaches, including 15N tracing techniques, mobile cavity ring down spectrometer, open- and closed-path FTIR spectroscopy, open-path lasers and quantum cascade laser systems, to quantify real-time fluxes of CO2, CH4, N2O and NH3 in agricultural environments.
Agroecosystem modelling and decision support
We develop and apply spatially referenced, process-based modelling (WNMM) to understand water and nitrogen dynamics, upscale field observations, and support decision-making for fertiliser and irrigation management.
Nitrogen cycling, fertiliser efficiency and emissions mitigation
Our research evaluates nitrogen loss pathways and mitigation strategies, including urease and nitrification inhibitors, controlled-release fertilisers and other smart fertiliser approaches that improve nitrogen use efficiency while reducing environmental impacts.
Integrated analysis of soil carbon and nitrogen dynamics
We investigate soil carbon and nitrogen processes in agroecosystems, including responses to management and climate drivers, and use experimental, synthesis and modelling approaches to strengthen mechanistic understanding and improve predictive capability.
Evidence for practice, inventories and policy
Our work supports evidence-based decisions by farmers, industry and policy makers, and contributes to emissions inventories, environmental assessment and the development of practical mitigation options for agricultural systems.
