Milorganite Research

On-going Research Projects for Milorganite Branded Products

• Environmental Phosphorus Effects From the Use of Milorganite® Fertilizers, Research at the University of Florida growing turf on sand with virtually no inherent nutrient holding capacity indicates Milorganite phosphorus moves to groundwater at a much lower rate than that of synthetic fertilizer phosphorus. The Water Extractable Phosphorus (WEP) analysis measures the tendency fertilizer phosphorus to move to groundwater. Milorganite fertilizers WEP is measured at less than 2% as compared to 85% WEP for synthetic phosphorus fertilizer.
• Bermuda Greens Establishment with Milorganite, University of Florida (Ft. Lauderdale, FL) This two year study is establishing rates of Milorganite® 6-2-0 to use in a greens mix to establish Tif-Green Bermudagrass greens. It is also analyzing leachate in an effort to review the environmental effects of various fertilizer regimes used in greens establishment.
• Bent Greens Establishment with Milorganite, University of Wisconsin (Madison, WI) This study established rates of Milorganite® 6-2-0 to use in a greens mix to establish Bentgrass greens. This study compared several fertilizer regimes and rates on an 80/20 sand/peat mix.
• Repairing Ailing Bermudagrass Greens , To test the theory that Milorganite® 6-2-0/sand topdressings can help improve damaged turf on greens, a study was conducted in the fall of 2005 on a ‘Tifdwarf’ research green at the UF/IFAS Ft. Lauderdale Research and Education Center. A demonstration trial showed that Milorganite applied as a topdressing alone or in a mix with sand, is useful for restoring areas on golf greens that have stress damage from unfavorable late summer environmental conditions.
• Characterization of Milorganite® 6-2-0 biosolids relating to phosphorus potential for soil water movement, University of Florida (Gainesville, FL) It has been found that phosphorus from various fertilizer types, especially from biosolids like Milorganite® 6-2-0, behaves differently in the environment. This two year study will review the environmental fate of phosphorus contained in Milorganite® 6-2-0
• Effects of Milorganite® 6-2-0 in reducing chlorosis in Ixora, demonstration plots (Coral Gables, FL) This demonstration plot is establishing rates and methods of application of Milorganite® 6-2-0 to resolve chlorosis in Ixora. Data to date show the iron in Milorganite® 6-2-0 will relieve these symptoms.
• Efficacy of Milorganite as a Deer Repellent, Berry College (Mt. Berry, GA) This study will review the efficacy of Milorganite® as a deer repellent, evaluate various application rates, and along with establish re-application timing for best plant protection. This work is in support of a pending US EPA Milorganite® Deer Repellent pesticide registration.
