Trial location(s) Wharminda, SA
Innovative deep nutrient application with fluid fertilisers locations
Aims
  • To identify suitable machinery for deep nutrient placement with economic and practical potential.
  • To evaluate the potential of injecting fluid fertilisers into soil using high pressure.
Key messages
  • High-pressure injection shows promise as an alternative method for applying fertiliser into the soil.
  • Deep banding fluid fertilisers with extra long knife points is another option which also showed promise.
  • This research is still in its early days.
