Micronutrients on grey calcareous soils - do they work? locations

To clarify the role of micronutrients in suspension on crop yield increases.

Key messages
  • Wheat grown on highly calcareous soils responded to zinc and manganese applications.
  • Micronutrients were most effective when they were applied in fluid form which provided economical responses.
  • There was no grain yield response when granular micronutrients were applied as a dry blend with granular NP fertiliser or as a coating on granules.
