Different sowing and topdressing nitrogen options in wheat locations
Aims

To evaluate nitrogen efficiencies of various nitrogenous fertilisers on wheat.

Key messages
  • There were adequate levels of nitrogen in the soil profile which limited response to any applied fertiliser.
  • There were significant yield increases from enhanced efficiency products such as Entec at sowing.
