Mauget Inject-A-Min Iron/Zinc is a formulation of water soluble Iron, Zinc and Manganese sulphates in a mild fertilizer base. This product useful for treating trace mineral deficiencies in trees which cannot be easily treated using traditional foliage or root fertilization methods - for example, in areas where spraying would be prohibitive or where nutrient leaching into ground water would be a concern.

Introducing fertilizers and trace minerals directly into the vascular system of the tree ensures quick response - improvement can usually be seen within a couple of days. These improvements in color and vitality have been shown to persist for up to 5 years compared to adjacent untreated trees.
