Nutri-Key Calcium Shuttle™

Liquid calcium fertiliser for plants

Calcium plays a key role in the development of plant and fruit cell walls, especially during the cell division stage. 


  • Protects the cell from toxins
  • Assists in slowing the ageing process
  • Helps stored fruit resist a range of breakdown conditions and rots


Nutri-Key Calcium Shuttle™ offers liquid calcium in a balanced formulation which covers the full spectrum of nutrition.

High-quality liquid calcium for plants

Adding a high-quality calcium source to a foliar nutrition programme will help mitigate plant deficiencies. The Shuttle® system delivers calcium to plants in a highly-available, complexed form; as the small molecule size increases the uptake of this key mineral.


Nutri-Key Calcium Shuttle™ also contains other secondary nutrients to avoid the problems that can occur when the correction of one shortage triggers another shortage due to the antagonistic effect of certain elements.

Frequently Asked Questions

As a key component of cell walls, calcium is a key nutrient for strong leaf and fruit growth. A calcium deficiency in plants can lead to poor root development, the yellowing of new plant tissue and abnormalities in fruit and vegetables. Foliar applications of liquid calcium can be used to correct or prevent calcium deficiencies and improve plant health and yield.

  • Calcium is an essential nutrient that plays many important roles in plant growth. Liquid calcium is used as a foliar fertiliser for better plant cell wall formation and normal cell division in new plant growth and proper fruit development.
  • Vegetables
  • Orchards
  • Vineyards
  • Ornamentals
  • Turf
  • Home gardens

Liquid calcium foliar spray provides necessary calcium to the plant, preventing stunted growth, leaf necrosis, short roots, fungal issues, weak stems and more. It’s critical for good cell division, which is especially important in plants that grow rapidly. Liquid calcium foliar sprays are a quick remedy for acute calcium deficiency in plants since the foliar application allows plants to absorb nutrients more efficiently than through roots.
