Residual phosphorus following a drought locations
Aims

To determine the residual value of the P fertilisers following a drought.

Key messages
  • P fertilisers applied in 2006 did not improve grain yield in 2007, even at the high P rate (18 kg P/ha).
  • In terms of residual value, there was no difference between granular and fluid P.
  • 2007 applied fluid P (TGMAP) at 6 kg P/ha increased dry matter at GS30 from fresh granular P and control treatments.
  • Soil testing is a useful tool for estimating P status in the soil.
