Finding out why fluid trace elements are more effective than granular on grey calcareous soils locations

To explain why some micronutrient fertilisers perform better than others in specific soil types.

Key messages
  • X-rays of small dishes of soil to which fertiliser had been added in the centre showed that fluid forms of copper, zinc and manganese are more mobile (diffuse further) in soil compared to granular forms.
