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.
