Trial location(s) Nyngan, NSW
Nyngan CWFS site - phosphorous carryover locations
Aims

To investigate "Can fertiliser rates be reduced after a drought year to allow for the use of residual P?"

Key messages
  • It was difficult to see the carryover of residual P into 2003 in this trial as some plots were affected by crown rot or common root rot (still to be determined).
  • The maximum wheat yield was achieved when 5 kg P/ha was applied in 2003 on top of 11 kg P/ha applied in 2002.
