Full On Fe is a stable, highly water-soluble form of chelated iron. Iron is an essential micronutrient for plant development. It is necessary for crop growth and food production. It plays a key role as it is involved in the synthesis of chlorophyll and in other enzymatic and metabolic processes without which plants cannot carry out their lifecycle. Iron is a component of many enzymes associated with energy transfer, nitrogen reduction and fixation, and lignin formation. Iron deficiency is manifested by iron chlorosis, which is not caused by a lack of iron in the soil. Still, rather than its low availability in a form that can be absorbed by the plant, there Fe- EDTA Chelate plays an important role.
