Boron deficiency made worse by

  • Sandy soils
  • Alkaline soils
  • Soils low in organic matter
  • High levels of nitrogen
  • High levels of calcium
  • Cold wet weather
  • Periods of drought

Boron is important for

  • Essential for root elongation, synthesis of nucleic acids and cell walls, plasma membrane integrity, carbohydrate and protein formation
  • Necessary for pollen germination and pollen tube growth
  • Leaf growth without deformation
  • Prevents yield losses caused by flower abortion
