By using DTPA chelation, this product aims to keep iron more plant-accessible across a broader pH range, helping greens, lawns, citrus, and hydroponic setups stay vibrant even when irrigation raises pH. This is designed as a practical option between economical EDTA-based chelates and premium chelates, offering a balanced price point without compromising performance for challenging environments.\u003c\/p\u003e\n\n\u003ch3\u003eWhy this iron chelate performs in alkaline soils\u003c\/h3\u003e\n\u003cp\u003eIn soils with higher pH, iron can become less soluble. The DTPA chelate in this formula is built to stay stable up to pH 7.5, which helps bridge the gap between standard chelates and more advanced options. Users may experience substantially improved iron uptake and reduced chlorosis compared with iron sulfate in tough alkaline conditions. The product contains 11% chelated iron, a level chosen to support steady plant-available iron while maintaining cost effectiveness.\u003c\/p\u003e\n\n\u003ch3\u003eWhat you might see on plants\u003c\/h3\u003e\n\u003cp\u003eUnder realistic conditions, new growth often shows a visible improvement within days. Foliar applications can lead to greening in about one to two weeks, while soil drenches tend to offer longer-lasting correction for four to six weeks. This makes it suitable for both quick touch-ups and ongoing correction in lawns, citrus trees, ornamentals, and hydroponic systems when high pH or hard water is involved.\u003c\/p\u003e\n\n\u003ch3\u003eHow to use\u003c\/h3\u003e\n\u003cp\u003eThis product is 100% water soluble, dissolving with no residue for flexible application in foliar spray, soil drench, fertigation, and hydroponics.
