Nutri-Key Calcium Shuttle

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”.


  • Small molecule size increases mineral uptake.
  • Also serves as a carbohydrate-based microbial promotant.
  • Contains “background 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.
