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

  • Respiration, photosynthesis and water regulation
  • Transport and accumulation of sugars in the plant
  • High effect on yield and fruit quality
  • Increase of crop height, girth, leaf growth and number of fruit per plant
  • Improves pulp content and fruit size
