Aims

The objective of this experiment, conducted at two sites in 2011 was to assess the response of wheat to zinc and/or copper in a standard cropping system.

Key messages

On these two sites, the addition of copper or zinc supplements to MAP had no effect on grain yield or grain Cu or Zn content. Based on the soil test, the Horsham site could have been considered marginal for Cu, but Zn levels were not considered limiting. Soil tests for micronutrients are unreliable and diagnosis of paddocks where crops can benefit from micronutrient supplements is also unpredictable.
