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

Calcium plays a key role in protecting the cell from toxins and in slowing the ageing process. Adequate fruit calcium assists longer storage life and helps stored fruit resist a range of breakdown conditions and rots. The Shuttle® system delivers calcium in a highly plant available complexed form. Nutri-Key Calcium Shuttle™ offers calcium in a balanced formulation which covers the full spectrum of “background nutrition”.

Key Performance

  • Ideal throughout reproductive growth
  • Superior Shuttle® chelation for enhanced uptake
