Long-term phosphorus trial - 2007 report locations
Aims

To determine the most economical rate of phosphorus (P) in a southern Mallee cropping system over time. 

Key messages
  • Since this trial began in 2003, there has been no significant economic response to applied P. The most profitable treatment over five years was where either no P or 5kg P/ha had been applied.
  • If considering reducing P rates in 2008, it is important that the amount of P that has been applied and removed over a 3-4 year period is calculated. If the P removal is not greater than P inputs then you can consider reducing P rates.
  • The 5kg P/ha rate maintained a neutral P balance after the 5 years, whereas the control had a negative balance of just under 20kg P/ha. The higher rate treatments failed to utilize applied P and subsequently accumulated a positive balance greater than 20kg P/ha.
