GRENA SUPERFERRO +S is recommended for the base fertilisation of crops requiring intervention on several levels: iron chlorosis and excessive limestone content are the two cases where it is important to intervene with GRENA SUPERFERRO +S, which provides an excellent corrective action against alkaline soils by balancing soil pH, thereby helping the iron-humate compound to be assimilated.
This compound is generated through Iron made assimilable by siderophore substances and its interaction with the Grena Matrix, based on humic and fulvic acids and amino acids, the latter being responsible for translocating the compound to the roots.
GRENA SUPERFERRO +S ensures a high supply of organic compounds that promote an overall improvement in soil fertility and a continuous availability of essential nutrients.
