In-season nutrient management 2017

Presented at Campbell Town, Tasmania GRDC Update
Field day, Cressy Tasmania, Australia

Summary of the talk :
  • N, S, B and maybe K may be deeper into the profile and access to these may be delayed or reduced.
  • Set N supply to meet yield potential – make water and radiation the limiting factor – not nutrition
  • Still a long way to go though so make N decisions in the light of that yield potential, especially denitrification losses.
  • Rate is more important than timing and source.
  • It’s not all about N – keep an eye on S, Cu and Zn. Tissue tests good and problem areas.
  • Keep in contact – Twitter, Crop Nutrition community of practice http://extensionaus.com.au/crop-nutrition/
