N2O loss equals dollars lost locations
Aims

To measure nitrous oxide losses from inhibitor treated and slow release fertiliser products and their effect on wheat yield and quality

Key messages

Nitrous oxide losses from nitrogen fertiliser products compared in this trial were low: 1 g N/ha/day or less. Granular urea and granular urea plus inhibitor fertiliser provided the greatest yield benefit this season. Potential benefits from different fertiliser products will be realised if seasonal conditions and timing of plant growth are matched.
