with chelated Iron and Magnesium
15% N - 6% FE
Replicated tests have proven SpeedyGreen will reduce, correct, and prevent iron deficiencies in turf. The iron in SpeedyGreen is naturally chelated. Chelation is the process whereby metals, e.g. iron and magnesium are protected from oxidation allowing entry into the plant through foliage and roots.
Most micro-nutrient fertilizers on the market today are chelated with EDTA. EDTA, along with the metals it sequesters, is persistent in soil has been found decades after application.
Science reports (EDTA) “Behaves as a persistent environmental pollutant enhancing the mobility and bio- availability and re-mobilization of heavy metals…and is a major concern.”
