Contributor Agriculture Kangaroo Island Incorporated
Trial location(s) Karatta, SA
Variable rate lime and fertiliser for grazing enterprises locations
Aims

To undertake a variable rate grazing trial in pastures.

Key messages
  • Without this intensive mapping the paddock would have been either under or over limed and fertilised resulting in either a loss of productivity or a waste of fertiliser/lime dollars and possibly both.
  • Whilst it’s economically beneficial to apply variable rate technology for a liming program, until more cost efficient soil testing methods are developed, the economic justification may not be there for soil nutrients.
