Nitrous oxide emissions in grain production systems locations
Aims

To measure N20 emitted by vetch, field peas and wheat stubble over summer and to determine whether
top-dressed inhibitor-treated and slow release urea products influence N2O emissions.

Key messages
  • N2O losses appear to be minimal from dryland low to medium rainfall farming systems; peak emissions of only 4.0 gN2O-N/ha/day were measured following rainfall.
  • N2O emissions from legume stubble over summer and with synthetic fertiliser applied in-crop were low.
  • An increase in soil water was the major driver of N2O emissions.
