Brief description

The project will quantify year-round greenhouse gas (GHG) emissions, water and nutrient fluxes in irrigated, broad-acre cropping systems of the Southern Murray Darling Basin (SMDB). Current and emerging irrigation and fertiliser management practices with and without chemical inhibitors to mitigate GHG emissions from irrigated cereal rotations will be compared. Fluxes will be monitored using automated chambers over crops in weighing lysimeters. The equipment enables replicated manipulation of water and nutrients in undisturbed soil columns beyond what is possible in the field. It also allows direct measurement of nitrous oxide (N2O) surface emissions, N2O fate and sources throughout the soil profile and indirect N2O emissions in leachates. The project will develop a suite of coincident water-nitrogen-GHG-crop, empirically measured datasets. The datasets will be made available for model framework development for predicting GHG emissions in grain cultivation and for mitigation strategy development.
