Trace Elements after Post Harvesting

As the harvest season is on a close, attention should be given to next year’s crop potential and time has come to take of that too.

Foliar application of Micro elements is very beneficial. The highly recommended micro elements to apply now are Magnesium, Zinc and Boron ( Most Important Zn & B ). Movement of both Boron and Zinc is minimal in the tree until extension growth commences.

Boron (B):
B involved in Calcium mobility, cell membrane integrity and cell wall polysaccharides and is well known to influence good pollination, seed set and fruit shape. It is prone to leaching and during winter levels can fall below the desired requirements for fruit production, therefore post harvest application of Boron plays an important role to ensure adequate levels at bud burst.

Zinc (Zn):

Zinc is essential for the production of the primary growth hormone – auxin and is required by a large number of enzymes and for chlorophyll production.

Magnesium (Mg):

It is also common to apply Magnesium at this time although it is quite mobile and deficiency can usually be corrected relatively easily during the growing season. Magnesium is part of the chlorophyll molecule and is
subsequently critical for photosynthesis.

Manganese (Mn) & Iron (Fe):

Manganese and Iron are also essential in photosynthesis through enzyme activation and electron transfer respectively. Iron has limited mobility in plants and both Iron and manganese uptake can be easily affected by high pH soil conditions
