Nutri-Key
Calcium Shuttle™
Liquid calcium delivered by Shuttle® chelator technology.
Calcium Shuttle is a liquid calcium fertiliser that uses Shuttle® chelation to keep calcium in a small, highly available molecular form, supporting plant and fruit cell-wall development, with secondary nutrients included so correcting calcium doesn’t trigger another deficiency.
Shuttle® chelation
Small molecular form for better uptake.
Cell-wall strength
Supports fruit & turf development.
Balanced nutrition
Secondary nutrients avoid new deficiencies.
Foliar calcium
Applied at critical growth stages.
Why Nutri-Key Calcium Shuttle
Calcium Shuttle uses Shuttle® chelation to keep calcium in a small, highly available molecular form, so it moves into the plant more readily than conventional calcium sources. It’s balanced with secondary nutrients, so correcting a calcium shortfall doesn’t create a new antagonistic-element deficiency.
It’s applied as a foliar calcium spray for turf, greenhouse crops and, especially, fruit, either at critical points in the growing season, or when root-based calcium uptake from the soil is inadequate.
Application guide
Applied as a foliar calcium spray, typically at critical growth stages or when root calcium uptake is inadequate. Zylem has not published an exact rate, confirm with a Zylem agronomist.
Guaranteed analysis
The exact % calcium is not publicly listed. Comparable international Nutri-Key listings reference 17.5 L and 1000 L pack sizes, but this has not been confirmed on the Zylem South Africa page: verify before publishing.
