Aims

To determine which combinations of nitrogen and zinc together with a single rate of phosphorus applied either as granular or fluid performed best on a range of soil types.

Key messages
  • Application of fluid phosphorus fertiliser on highly calcareous grey soil (P responsive) at Miltaburra significantly increased shoot dry weight and uptake of phosphorus, nitrogen, zinc and manganese and increased yield by 14% compared to granular phosphorus fertiliser application.
  • Application of fluid phosphorus fertiliser on red-brown calcareous soil at Emerald Rise (non P responsive) increased shoot dry weight and uptake of phosphorus, nitrogen and manganese relative to granular phosphorus fertiliser application.
  • On the red brown calcareous soils the addition of nitrogen and zinc to the fluid phosphorus fertiliser increased grain yield by 11% with no effect when added to the granular phosphorus fertiliser.
  • At Cowell (red brown calcareous soil) the use of zinc with fluid phosphorus fertiliser showed a small increase in zinc concentration in tissues but no other benefits.
