Copper deficiency made worse by

  • Organic soils
  • Chalky soils
  • Sandy soils
  • Reclaimed heathland
  • High nitrogen applications

Copper is important for

  • Lignin formation, chlorophyll performance and regulation of superoxide radicals
  • Necessary for blue pigment plastocyanin, seen in broccoli florets
