Quick Facts About Phosphorus

  • Phosphorus is present in every living cell, both plant and animal.
  • Helps with the transformation of solar energy into chemical energy, proper plant maturation, and stress mitigation.
  • Form used by plants: H2 PO4 (when soil pH <7) and HPO4- 2 (when soil pH>7).
  • Phosphorus availability is critical during the early growth stages to ensure a quick and healthy start.

Role of Phosphorus in Plants

  • Stimulates early season growth.
  • Grows deeper and stronger roots.
  • Hastens plant maturity and promotes seed production.
  • Phosphorus functions as one of the main promoters of photosynthesis, nutrient transport, and energy transfer via energy-rich linkages (ATP).
  • Phosphorus is involved in the formation of all oils, sugars, starches and encourages early plant growth.
  • Phosphorus is utilized by plants to form nucleic acids, which regulates protein synthesis.
  • Involved in regulating stomatal opening and closing.

Phosphorus Deficiencies:

Deficiency Symptoms

  • Slow growth and stunted plants.
  • Abnormal purplish coloration of foliage starting from older leaves.
  • Delayed maturity.
  • Poor grain, fruit and seed development.
  • Fruits and old leaves drop prematurely.

Factors Affecting Deficiencies

  • Cold soil temperature, wet soils reduce the supply or conversion of unavailable or labile Phosphorus into the soil solution P.
  • Low soil pH (< 6) and high soil pH (>7 .2) reduce the availability of Phosphorus to the plant.
  • Higher available Iron and Calcium in soil can limit Phosphorus availability.
  • Excessive Phosphorus fertilizer can aggravate Iron and Zinc deficiencies and increase the soil salt content.
  • Nitrogen fertilization may increase Phosphorus concentration in plants by increasing root growth and by decreasing soil pH as a result of the absorption of ammonium (NH4+) and thus increasing the solubility of fertilizer Phosphorus.
