Application Details
MarKey® Iron 6% EDDHA Chelate (3% Fe Ortho-Ortho EDDHA) may be dissolved in water or liquid fertilizers, then applied to the soil as a spray or via drip, sprinkler or furrow irrigation. It may also be dry blended with dry fertilizers or inert carriers (such as sand), then broadcast, banded or side-dressed. For best results, this product should be incorporated into the root zone by tillage, drenching, irrigation or rainfall. MarKey® Iron 6% EDDHA Chelate may also be applied via foliar application.
Nutrient Function
Iron is essential for chlorophyll formation and supporting healthy vegetative growth and efficient photosynthesis. It is critical for oxygen production in the plant. Iron is a mobile nutrient but is not transported from old leaves to new ones, often resulting in deficiencies in older leaves. Iron availability in the soil declines as soil pH increases above 4.
