    ALPINE MicroBolt Zn micronutrient is manufactured by utlizing the highest quality raw materials to provide a very agronomically efficient source of plant availiable Zinc. The chelate used is compatible with high orthophosphate products. ALPINE MicroBolt ZN micronutrient delivers:

    • Maximum plant nutrient solubility - in furrow or foliar
    • Minimal salt index
    • No application equipment corrosion
    • Compatibility with most other liquid fertilizers
    • Tank mixable with most pesticides
    • Low impurities
    • Neutral pH


    Application Rate: Use 1/2 to 1 Litre/ac either in furrow or as a foliar spray.
    Optimum rate of application will vary between fields, depending on soil pH and organic matter content. Product should be used on the basis of soil and/or tissue analysis. 
    Maximum of 2L/ac of any combination of micronutrients when mixed with a seed placed starter fertilizer. 

    Role of Zinc

    • Zinc is crucial in flower formation. i.e. Canola
    • Zinc acts like 'antifreeze' in the plant to give early and late frost protection
    • Zinc controls the synthesis of many plant growth regulators
    • Animals deficient in Zinc require twice as much feed to attain the same weight
    • Zinc is unavailable in high pH soils
    • Zinc improves germination rate and plant vigor
    • Zinc is necessary for starch formation and proper root development
    • Zinc is also essential for seed formation and maturity


    Zinc Soil Availability

    • The availability of Zinc is directly related to 3 soil factors:
      • the amount of Zinc supplying minerals
      • the amount of available phosphate and
      • soil pH (Calcium Carbonate)
    • Soils with both high pH and high phosphate levels, will make the available Zinc into the complexed for form - ZnPO4
    • When Zinc is precipitated in this form, it is unavailable and deficiencies can occur 
    • 1.1 - 3.0 ppm in soil test is medium amount

    Zinc in the Leaf

    • Research indicates the P to ZN ratio in leaf tissue should be 100 - 150 : 1
    • Whenever the P content of a plant increases, so must the Zn concentration in order that this ratio be maintained
    • Sufficiency tissue test ranges in ppm
      • Canola: 25 - 45
      • Small grains: 25 - 50
      • Peas: 40 - 80
      • Corn @ tasseling: 25 - 50
      • Soybeans: 25 - 50

    Deficiencies Symptoms

    • The most common nutrient deficiencies include interveinal chlorosis on older leaves with shortening of the intermodal area
    • This shortening often leaves a short compressed plant with a rosette appearance
