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

  • Resistance to cold injury and drought
  • High yields through increased biomass and head weight
  • Consistent, early and evenly matured marketable crop
