Michelle Bammann, Agronomist for Sonic Essentials in South Australia has provided this handy reference and included a zinc application reckoner for reference.( Send an email request for reckoner )
Just a few highlighted
reasons below to why we should be encouraging the use of oxide foliar zinc at
the moment. I strongly believe that in these bleak, cold and wet conditions,
zinc is as important as N. I have also included a ready reckoner for
application rates on all of the Icon Products. ( Send an email request for reckoner )
Zinc deficiencies appear to
be more likely to occur in the following situations:
• High phosphate, high pH
(alkaline) soils;
• Cold wet and poorly aerated soils, low in vesicular arbuscular
mycorrhiza (VAM);
• Areas where the topsoil has
been removed by either erosion or by land levelling;
• Long fallows where VAM is
low; and,
• Where restriction to root growth has occurred such as
wheel tracks, chemical damage, hard pans or waterlogging.
Zinc is essential for many plant functions. Some of them are
- Production of Auxins, an
essential growth hormone.
- It activates enzymes in protein
synthesis, plus is involved in the regulation and consumption of sugars
- It is necessary for starch formation and proper root development.
- Zinc influences the rate of
seed and stalk maturation.
- It is necessary for the
formation of chlorophyll and carbohydrates.
- The presence of adequate amounts in the tissue enables the plant to
withstand lower air temperatures.
Happy to answer any questions you may have
