First study to quantify N2 from Australian pastures using the 15N gas flux method.

Nitrifier-denitrification contributed to N2O emissions at high WFPS.

N2 emitted accounted for a third of applied N fertiliser at high WFPS.

These N2 losses are a significant loss of fertiliser N from subtropical pastures.
