Subsoil Nutrition on clay spread soil locations
Aims

To investigate potential long term negative effects on crop yield of interactions between clay spreading or delving with subsoil nutrition (micronutrients).

Key messages
  • Sandy soil spread with clay that has a high level of calcium carbonate (lime) has the potential to cause extreme manganese (Mn) deficiency, leading to poor crop growth and yield. 
  • Clay must be tested before spreading to gauge the potential for problems and adjust the clay rate accordingly. 
  • Nutrition issues relating to clay spreading can still be apparent many seasons following the clay spreading.
