I heard that Milorganite contains heavy metals. Is that true?
Yes, that is true. All fertilizers, both organic and synthetic, contain some heavy metals. In fact, plants need some heavy metals, such as zinc and copper and molybdenum, for normal, healthy growth. Milorganite meets the U.S. Environmental Protection Agency (EPA) “Exceptional Quality” criteria which establishes the strictest concentration limits in the fertilizer industry for heavy metals (please refer to Specifications & Regulations). Many other common fertilizer products exceed the limits for metal concentrations established by the EPA “Exceptional Quality” standards. Milorganite, though, can be used with confidence for all your fertilizing needs, including use on all types of grass, trees, shrubs, flowers and vegetable gardens. Please refer to the Home Use or Professional Use sections for application information.
