Speedfol® Rexene® FeE13 SP is a product developed for iron deficient crops, intended for foliar application. This method is recommended when the soil is neutral to alkaline or when soil application is not feasible for other reasons. The "13" in the name refers to the effective amount of iron, which is 13.3%, fully chelated with EDTA. "SP" stands for Soluble Powder, with a solubility of 90 g/l at 20°C. The product has a pH stability of 1.5 to 6.5, and EDTA chelation helps prevent precipitation losses during tank mix preparations.
