Aims

To comment on seedbed utilisation calculating safe fertiliser rates,

Key messages
  • SBU is the spread pattern of seed and fertiliser relative to row space, expressed as a percentage.
  • Safe urea N rates in Canola are approximately half that of wheat at the same SBU %.
  • When the SBU % is > 45%, safe N rates become less than half that of wheat.
