YaraTera Rexolin Q40 is a high-performance, professional-grade microgranular fertilizer containing iron chelated with EDDHA. Its main advantage is its extreme stability and availability to plants even in challenging, highly alkaline, and calcareous (lime-rich) soils where standard iron sources (like iron sulfate) or weaker chelates (like EDTA) instantly lock up, precipitate, and become useless.
Main Advantages Ironclad Stability: Unlike other iron forms, Rexolin Q40 keeps iron fully active and available to roots even in extremely high pH environments (up to 10.0). Crop Safety: When used at recommended dosages, the formulation minimizes the risk of leaf scorch or root burn. Excellent Solubility: The microgranules dissolve completely without leaving a residue, ensuring fertigation lines and drip emitters do not clog.
