N X P responses in canola locations
Aims

To determine the relative requirements for nitrogen (N) and phosphorous (P) in canola.

Key messages
  • There was a strong response to P but no response to N
  • Plant tests showed that the crop was unlikely to respond to N
  • 0N 24P was nearly $300/ha more profitable than 80N 16P!
  • Profitability is driven by getting the N and P balance AND application rates right.
