Brief description

This trial has been completed in late December 2013 at Gatton. The treatments were:
1. Control (Granular urea, 40 kg N/ha, surface applied)
2. Granular urea (40 kg N/ha, surface applied) + urease inhibitor (NBPT, Green ureaNV)
3. Granular urea (40 kg N/ha, surface applied ) + nitrification inhibitor (DMPP, Urea with ENTEC)
The treatment areas (30 m) were located 50 m from all external boundaries and from adjacent treatments. Treatments were hand spread and applied to the 30 m diameter treatment areas in strips to ensure even application. Emissions of ammonia and nitrous oxide were measured, using passive samplers and closed static chambers, respectively. Soil mineral N, grass biomass and 15N recovery were also measured.
