Effects from long-term application of nitrogen and phosphorus fertilisers locations
Aims

To look at the combination of four phosphorus rates (0, 9, 18 and 36kg P/ha applied via triple superphosphate) and five nitrogen rates (zero, 20, 40, 80 and 160kg N/ha applied via urea) as well as two nitrogen timings, at sowing and top-dressed.

Key messages

In this trial, there has been a positive response to phosphorus fertiliser applied at 9kg/ha at sowing and a positive response to nitrogen fertiliser applied at 20kg/ha. There has been a negative response to applied nitrogen both at sowing and top-dressing at higher than 20kg N/ha rates, which can be attributed to low growing season rainfall (GSR), which has occurred through prolonged periods over the course of the trial.
