Key Function of Elements

  • Ca enables nitrogen-fixing bacteria to form nodules on the roots of leguminous plants.
  • Ca in the form of calcium pectate, it is responsible for maintaining plant cell wall integrity resulting in improved mechanical strength and less lodging.
  • Ca when Ca is deficient, new tissue such as root tips, young leaves and shoot tips often exhibit distorted growth from improper cell wall formation.
  • Mg is required by all crops as part of chlorophyll molecules that capture the sun’s energy, essential for photosynthesis, growth and yield.
  • Mg aids in phosphate (P) metabolism, facilitating movement of P compounds as well as carbohydrates through the plant.
