Year(s) 2003
Contributor Liebe Group
Trial location(s) Dalwallinu, WA
P Nutrition of wheat locations
Aims

To investigate the response of wheat to phosphorus fertiliser grown on an alkaline crumbly clay soil type.

Key messages
  • Drying soil conditions at the time of sowing, caused a poor initial germination of seedlings.
  • Grain yield tended to increase as the rate of phosphorus fertiliser applied increased.
  • The liquid NP source performed no better or worse than the solid NP source.
