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

  • Better crop establishment
  • Good plant development early in the season
  • More even maturity reducing grain losses at harvest
  • Improves yield
  • Brings forward harvest date
