• 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.
  • 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”.
  • Chelated copper with backup from all other nutrients reduces copper-based tie-ups, i.e. copper-induced zinc deficiency.

    Copper is a cell strengthener and seed builder. The Shuttle® system delivers copper in a highly plant available chelated form. Nutri-Key Copper Shuttle™ offers chelated copper in a balanced formulation which covers the full spectrum of background nutrition.
  • Timing is the trick with trace mineral applications. Manganese is a reproduction booster and timing should reflect that feature.

    Manganese is often termed the seed energiser and it is an important element for seed germination and seed formation. Nutri-Key Manganese Shuttle™ offers chelated manganese in a balanced formulation which covers the full spectrum of background nutrition. DOWNLOAD PRODUCT BROCHURE

  • Zinc offers the most pronounced pound for pound response of any trace element.

    Zinc controls the production of auxins – plant promotants that govern leaf size. Leaf size determines the efficiency of photosynthesis so, in this context, zinc is arguably the most important of the trace elements. Certainly it can give the most cost-effective response of any trace element. Nutri-Key Zinc Shuttle™ is a high analysis chelated zinc, suitable for all situations in horticulture.
