To determine if there was an economical benefit in top-dressing nitrogen on a steep sandy rise, with a good zinc history at Hopetoun.
Key messages
During the extremely dry 2006 season the addition of micronutrients had no significant effect on crop performance and there was no benefit, in terms of grain yield, from the application of nitrogen, regardless of product.
There is no benefit to apply micronutrients when levels are adequate at GS30 and when there is a good history of applications.
