Nitrogen and phosphorus fertiliser additives and replacement products locations
Aims

To investigate conventional phosphorus fertilisers and alternative sources of phosphorus on the grain yield and quality of wheat.

Key messages
  • For all treatments grain yield or quality was not increased compared to conventional fertiliser applications of 80 kg/ha urea alone or 60 kg/ha urea plus 50 kg/ha DAP.
  • Treatments selected for nitrogen and phosphorus tissue tests showed no difference in nutrient concentrations.
