Nutri-Key Calcium Shuttle™
Liquid calcium fertiliser for stronger cells, better fruit, and longer shelf life.
Nutri-Key Calcium Shuttle™
Calcium plays a key role in the development of plant and fruit cell walls, especially during the cell division stage. Nutri-Key Calcium Shuttle™ protects cells from toxins, assists in slowing the ageing process, and helps stored fruit resist a range of breakdown conditions and rots.

Key Benefits
Strengthens Cell Walls
Calcium is the primary building block of plant and fruit cell walls, essential for structural integrity.
Protects from Toxins
Adequate calcium prevents toxin accumulation in cells, reducing physiological disorders.
Slows Ageing Process
Calcium-rich cell walls are more resistant to enzymatic breakdown, extending shelf life.
Improves Fruit Storage
Reduces post-harvest losses from calcium-deficiency disorders such as bitter pit and blossom-end rot.
Technical Information
Nutri-Key Calcium Shuttle™ delivers calcium in a highly soluble liquid form, using Shuttle® chelator technology for enhanced absorption at the leaf and fruit level.
Application
Apply as a foliar spray during cell division stages and fruit set. Critical application windows include early fruit development and post-harvest preparation. Consult your Zylem agronomist for timing.
