Agricultural Greenhouse Gas

The Agricultural Greenhouse Gas group measures, models and mitigates direct and indirect greenhouse gas emissions from diverse agricultural systems, including dairy, cereals, vegetables, sugarcane and intensive feedlots, as well as ammonia deposition surrounding intensive feedlots.

We apply micrometeorological techniques, including Fourier Transform Infrared (FTIR) spectroscopy, quantum cascade lasers, and other approaches, for field-scale measurements. Emissions reduction projects look at urease and nitrification inhibitors and controlled-release fertilisers (ARC Hub for Smart Fertilisers), and modified coals for decreasing NH3 and N2O emissions from agricultural systems. To upscale field findings, we have developed an internationally acclaimed, spatially referenced and process-based water and nitrogen management model (WNMM), and a Decision Support System for optimum irrigation and fertiliser N application.
