Milorganite® is a great organic, nitrogen rich, and cost effective fertilizer. Over 85% of the nitrogen in Milorganite is in a slow release form, which means that plants access the nutrients when they need them. The gentle action of this fertilizer ensures no burning even with over-application and strong green growth rather than excessive growth produced by other fertilizers. Milorganite is a popular product for home owners, turf professionals and golf course managers.
