Ongoing Research Projects for Milorganite

Milorganite recognizes the need to continuously research our product. We also look at the effect that the use of Milorganite fertilizer has on the environment.

Uptake of the Pharmaceutical Triclosan in Vegetables, University of Florida (Gainesville, FL) 
Research indicates that  based on the EPA Triclosan reference dosage, it would be impossible to consume sufficient quantities of any of the vegetables to create adverse health effects.     

Efficacy of Milorganite as a Deer Repellent - Food Plots, University of Florida (Athens, GA)
This study reviewed the efficacy of Milorganite as a deer repellent, evaluated various application rates, and re-application timing for best plant protection.

Efficacy of Milorganite as a Deer Repellent - Ornamental Plantings, University of Georgia (Athens, GA)
This study reviewed the efficacy of Milorganite as a deer repellent, evaluated various application rates, and re-application timing for best plant protection.

Milorganite's effectiveness as a fertilizer for tomatoes, University of Wisconsin (Madison, WI)

Characterization of Milorganite biosolids relating to phosphorus potential for soil water movement, University of Florida (Gainesville, FL).  This study concludes that phosphorus from various fertilizer types, especially from biosolids like Milorganite, behave differently in the environment. This two year study indicates that Milorganite is a low environmental phosphorus risk.

Environmental Phosphorus Effects From the Use of Milorganite, University of Florida (Gainesville, FL)
This study indicates that 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 of fertilizer phosphorus to move to groundwater. Milorganite 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 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 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, University of Florida, (Ft. Lauderdale, FL)
This 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.

Effects of Milorganite in reducing chlorosis in Ixora, demonstration plots (Coral Gables, FL)
This demonstration plot is establishing rates and methods of application of Milorganite to resolve chlorosis in Ixora. The iron in Milorganite relieves these symptoms.
