Abstract

Grain production is a net producer of greenhouse gases (GHG) via fertiliser, herbicide and farm machinery usage. In south-western Australia, previous research demonstrated that applying N fertiliser as urea contributed ca. 80% to total on-farm emissions by emitting carbon dioxide (CO2) via urea hydrolysis, and nitrous oxide (N2O) via soil biological activity. This project will determine if on-farm CO2 emissions from urea can be decreased by substituting urea with grain-legume fixed N; and if on-farm N2O emissions can be decreased by raising soil pH (via liming). Nitrous oxide emissions will be measured on a sub-daily basis from lupin-wheat rotations (limed and unlimed) using soil chambers connected to a fully automated system that enables simultaneous determination of greenhouse gases (N2O, CH4, CO2). Research findings will equip grain producers with strategies to manage on-farm GHG emissions.
