Nutrient Requirements Throughout Turf's Growth Cycle

Here you find an overview of nutrient requirements and the role they play throughout turf's growth cycle.


Root growth and establishment

  • K promotes rooting and the storage of carbohydrates
  • P is a key component of ATP and promotes root development, maturation, establishment and tillering
  • Ca is responsible for proper cell division and assists in protecting new plant tissue

The crown growth zone

  • K promotes meristematic tissue and increases thickness of outer cell walls improving abiotic and biotic stress tolerance
  • B is involved in auxin metabolism, root elongation, protein and phosphate  utilization
  • Zn is involved in the conversion of ammonium to amino nitrogen, and is important for the development and function of growth regulators

Leaf growth and healthy canopy

  • N is used in the formation of proteins and stimulates leaf growth by producing new, darker green leaves
  • K balances turgor pressure within cells and regulates water loss through transpiration
  • Mg is an important component for chlorophyll production and activates enzymes for phosphate metabolism and cell respiration
  • S is required for protein synthesis and nitrate metabolism
  • Fe is essential for chlorophyll formation, increasing color and shoot growth
  • Mn plays a key role in photosynthesis and oxide-reduction reactions in cells
  • Mo enables nitrogen utilization
  • Cu serves as a catalyst in photosynthesis and respiration


Note: Every nutrient plays an essential role throughout turf's growth cycle. The intention of this illustration is to visually highlight the most critical nutrients for turf and their roles. Yara recommends soil and tissue analysis for precisely identifying nutrient needs. Contact us for more information.
