Green-T® 12 Iron is an Iron, Manganese and Magnesium glucoheptonate chelate liquid that produces a deep green turf blade without excessive growth. The glucoheptonate chelate protects the Iron, Manganese, and Magnesium from tying up in the soil, while allowing the micronutrients to be available to the plant. The results in turf response that is visible within 12 hours after application. Green-T® 12 Iron's "3-1 ratio" of Iron and Manganese promotes a "natural" deep green turf for an extended period of time. Iron and Manganese act as an enzyme that enhnaces photosynthetic and repiration systems. It assists chlorophyll synthesis and is used as a reaction catalyst. The urea nitrogen enhances the uptake of these secondary and mirco nutrients within the plant.
