Sandy soils on Kangaroo Island locations
Aims
  • To investigate the role of a range of nutrients applied both on the surface and at depth, on crops grown on sandy soils.
Key messages
  • Deep ripping in most cases improved plant vigour and increased yield although responses were variable between the deep ripping treatments.
  • Although potassium had visual responses at most sites it only translated into increased yields at one site.
  • Nutrismart appeared to have no impact on barley production.
