Investigation of the benefits of specialty nitrogen products and liquid nitrogen options in cereals locations
Aims
  • Assess the effect of nitrogen timing on crop response.
  • Assess the effect of nitrogen placement on crop response.
  • Compare a range of liquid nitrogen fertilisers with granular urea.
  • Assess the effectiveness of numerous products aimed at controlling the release of nitrogen.
Key messages

Urea applied at 200 kgN / ha recorded significant yield increases over all treatments. Applications of straight urea at DC61 and or DC65 were unable to significantly increase grain protein when compared to specialty products.
