Phosphorus deficiency made worse by

  • Acidic or very alkaline (calcareaus) soils
  • Low organic matter
  • Cold or wet conditions
  • Crops with a poorly developed root system
  • Soils with low P reserves
  • Soils with a high phosphate capacity
  • Iron rich soils

Phosphorus is important for

  • Essential for root development, especially in early growing stages
  • Involved in growth processes and plant development like leaf formation and expansion, shoot growth, flower initiation and bunch size
  • Sustained optimum yield
