NANO Iron works by increasing the levels of Iron within a plant, this allows the plant to capture light much more efficiently (Photosynthesise) which gives the plant increased energy for root growth and oil production, whilst also increasing vegetative matter, flowering sites and ultimately yield.
The NANO Iron is so small (20 nanometers) that the plant can uptake it using minimal energy. The particle size, combined with the amino acid that we chelated it with, means that the plant has access to an unlimited supply of Iron which has the effects mentioned above.
There is no magic with NANO, just science. That's why we let the product do the talking and the science do the marketing.
NANO Iron (Fe3O4) occurs naturally in nature as the mineral magnetite. Magnetite is one of the most abundant minerals found on the planet and it is the most magnetic of all the naturally-occurring minerals on Earth. The reason we use magnetite is that when the Iron (Fe3O4) is made available to the plant, it already has the metabolic pathways to make use of NANO Iron due to plants evolving alongside this natural mineral and not treated as a foreign body as with other Iron fertilisers.
Traditionally, all metals used as a fertiliser have to be chelated, this is because most fertilisers contain phosphate salts that, in the absence of chelating agents, typically convert these metal ions into insoluble solids that are of no nutritional value to the plants. EDTA (Ethylenediaminetetraacetic acid) is the typical chelating agent that keeps these metal ions in a soluble form.
Some studies claim that EDTA can be toxic, so NANO has moved away from the traditional method of chelating metals and instead wrapped the Fe3O4 in an amino acid called Lysine. Lysine is naturally occurring and completely releases the Iron to the plant, unlike chelates that try their best to keep hold of the metals. Chelating used to be the method of choice for removing toxic metals from the body, so they are very good at gathering metals and keeping hold of them… not very good when you’re a hungry plant!
