Trial location(s) Warradarge, WA
Urease inhibitors locations
Aims

To determine the effectiveness of urease inhibitor products.

Key messages
  • The site was very responsive to nitrogen (N) fertilizer. 30kg N/ha increased yields by about 0.5 t/ha (18 kg grain/kg N).
  • 12mm rain fell 3 days after the N applications in June. This would have limited volatilisation losses.
  • The trial site was also quite variable and no response to the urease inhibitors was measured.
  • Hectolitre weights were 75-77 kg/hl, and screenings about 3%.
