Nutri-Key Boron Shuttle™

The relationship between boron and pollen viability is so intimate that all crops should receive a foliar application of boron prior to flowering.

Boron is the most leachable of all trace elements and consequently deficits are common. Boron is required as a calcium synergist and is very important in the early reproductive period of the crop cycle. Nutri-Key Boron Shuttle™ offers complexed boron in a balanced formulation which covers the full spectrum of background nutrition.


  • The perfect boron foliar for a pre-bloom application in all crops.
  • Boron influences the cell division potential of calcium during periods of rapid growth or fruit formation.
  • 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.
