There is a myriad of different formulations of elements available to growers at present. Oxides, Sulphates and EDTA chelates are the most commonly recognised formulations; however, these formulations have been superseded by 3rd generation Biomin Glycine chelated minerals.
It is a patented process of chelation whereby every metal ion is bonded with two Glycine (smallest amino acid) molecules creating a fully chelated product named BIOMIN. The plant recognises this molecule as a proteinaceous molecule allowing it to travel in the phloem quite readily to the growing points such as flowers and berries where it is required, as well as replenishing leaf levels. Glycine chelation technology allows metals to be mobile elements whereas elemental minerals, outside of this technology have low mobility within the plant.
The delivery method of these ‘bio-available’ minerals is not conventional, un-like products such as Oxides, Sulphates and EDTA based trace elements. The latter products can marginally reduce deficiencies, but the speed by which the elements are released from these products and transported into the growing points of plants is very slow, compared to the transportation of elements in the Glycine form.
Glycine chelation provides tremendous advantages due to its increased absorption and translocation of minerals within plants.
They are highly systematic, non-phytotoxic, 100% soluble and economical due to their high availability. Glycine chelates were developed for the conventional market however they are generally registered by organic certifiers, allowing organic growers to utilise this technology also.
The greatest advantage in foliar nutrition is the ease of application. However, for a foliar product to function and benefit your plants, it must firstly be highly soluble. If your selected product is not 100% soluble this results in applying the product onto the plant and not into the plant where it is required. Non-soluble products sit on the plant surface and may contaminate tissue analysis readings rather than penetrating the plant providing nutrition where needed. Glycine technology has revolutionised the application of elements such as Zinc, Boron and Calcium, which in elemental form have low mobility.
This internationally patented technology now enables elements to completely permeate fruit and leaf tissue, including those with waxy cuticles such as citrus and avocado, without reliance on stomata opening. The intake of these elements can now be mobilised via both the phloem and xylem with systematic action to the growing points where they are most needed.
