Product enhancers locations

To determine whether phosphorous (P) recovery could be improved with the use of 'product enhancers', or by 'biologically enhanced fertiliser approach'.

Key messages
  • From soil tests we knew that P was going to be the limiting factor.
  • This trial shows that there is no substitue for keeping your P rates up. For example a ~$90/ha investment achieved a return of $483/ha.
  • It also show the importance of soil testing.
  • Plant analysis did not show any improvement in P uptake from either product enhancer and neither of these'enhancers' improved crop yeilds.
