Micronutrient Field Evaluations

A summary of six experiments on field responses to micronutrients in western Victoria.


Objective – to compare delivery strategies for Zinc and/or Copper and/or Manganese in wheat under field conditions. Site selection: Any nutrient response experiment depends on selecting sites where there is a good probability of response. For Zinc and Manganese the most likely situations are alkaline sandy soils. A high P content will reduce Zinc and drought will also reduce the availability of both. Copper deficiency is most common on acidic sandy soils with a high organic matter content. Read more

Interpretive Summary


Six field evaluations of micronutrients on wheat were undertaken in Mallee (1 site), Wimmera (3 sites) and Western District (2 sites) of Victoria, Australia, in collaboration with various research partners. Both Cu and Zn supplements were evaluated on sites typical of the regions to assess the likelihood of responses and to add additional field data to the GRDC Micronutrient Scoping study.


During 2011 and 2012, six micronutrient field experiments were undertaken with cooperators from across Victoria. Sites selected on the basis of soil tests and cropping history were likely to respond to either Cu or Zn. The experiment in the Mallee investigated the effect of different presentations of Cu on what would be expected to be a Cu responsive site.
