Nitrogen sources and placement in wheat locations
Aims

To determine the agronomic effectiveness of different nitrogen fertiliser sources and placements in wheat.

Key messages
  • Urea increased wheat grain yield significantly over the nil when banded at sowing.
  • There was no significant difference between urea, UAN or MAXamFLO when applied at the same rate of nitrogen and incorporated by sowing, banded or applied at pre-sow, banded and post.
