Potassium deficiency made worse by

  • Acidic soils (low pH)
  • Sandy or light soils (leaching)
  • Drought conditions
  • High rainfall (leaching)
  • or heavy irrigation
  • Heavy clay (illite) soils
  • Soils with low K reserves
  • Magnesium rich soils

Potassium is important for

  • Helps to optimise leaf quality
  • Optimises plant water management
  • Potassium has been closely associated with resistance to disease in many plants
  • Improves resistance to low temperatures
