Ironite is a mineral that contains 4.5 percent iron by weight. To supply 0.7 ounces of iron, add approximately 1 pound of Ironite per 1,000 square feet; do not apply more than 2 pounds per 1,000 square feet.
How do I know if my lawn needs iron?
Grasses, in general, are vulnerable to a conflict of interest in the spring. While rising air temperatures and longer days encourage rapid development, the cold soil of spring suppresses the biological and chemical activity that makes nutrients accessible to plants. This effect is particularly noticeable in lawns that early-season applications of soluble nitrogen have enhanced. Since the amount of available iron in your soil may not be sufficient for the high nutritional needs associated with exuberant spring rise, now is an excellent time to add Ironite. In soil with a high pH, supplemental iron, including soluble forms like Ironite, may become fixed into inaccessible forms. Use the liquid type of Ironite if the soil is alkaline so that the grass can consume more iron from its leaves.
Why use ironite in soil?
Use the liquid type of Ironite if the soil is alkaline so that the grass can consume more iron from its leaves. While most soils contain enormous amounts of iron compared to the quantities required by plants, most of this iron is bound up in ways that roots cannot absorb.
