For dark green, healthy plants, Spring 138 iron chelate is a 6% fully chelated EDDHA iron for soils that are alkaline and calcareous, including soils with a pH greater than 7.0. It helps prevent iron from binding with other compounds in the soil so it can stay in form. Adding Iron will ensure improved health and quality of plants. It can be used in nurseries, gardens, landscape plantings, and turf through soil application or foliar spray.
