Petro 33 Ferro Zolfo is an organic fertilizer that nourishes plants in a balanced and constant manner over time. The product includes RyZea technology, which releases particular organic acids that remove nutrients from soil minerals, increasing their availability for the plant. In addition, Petro 33 + Iron Sulphur + RyZea, thanks to the latter, is a completely exclusive formulation deliberately enriched with special known chelating agents (e.g., glycine), which “bind” soil nutrients, conveying them to the plant more easily and effectively. Among other components, RyZea provides a high percentage of amino acids that improve plant recovery after winter stasis.
