GRENA SUPERFERRO

GRENA SUPERFERRO is particularly suitable for soils with iron deficiency as it contains GRENA organic matrix and iron from iron sulphate. The presence of humic and fulvic acids allows stability in the mineralisation process which, in their absence, would occur more quickly and give rise to leaching. Humic and fulvic acids are in fact responsible for the formation of complexes; for example, humic acid with iron becomes a humic iron compound. The humic iron compound is recognized by the plant and is therefore more assimilable. Naturally contained amino acids are in turn activators of root proliferation and chelation. That allows the root system to absorb mineralised NPK in the soil and promote the production of organic compounds to increase the absorption of nutrients including iron. This is why fertilisation with GRENA SUPERFERRO is essential to treat and prevent ferric chlorosis:
• to treat because iron is immediately available
• to prevent the creation of iron reserves for the subsequent phenological phases of the plant.
