    I purchased this product for use as a mordant, rather than a fertilizer.
    Very affordable, fast shipping and works great : )

    Iron Sulfate is a great additive to your liquid feedings. You can keep your lawn green during the summer and reduce the nitrogen. We use this product along with the Kelp/Humic Acid blend when feeding lawns and trees.

    Just bought 30lbs for my pumpkin patch, using this to raise iron without adding sulfur
    arrived neatly boxed and bagged with no spills
