Researchers at the 610-acre Illinois State University (ISU) Farm near Lexington, Illinois, have been addressing the issue of manure and odor management with a number of demonstration initiatives at the facility’s 200-sow farrow-to-finish unit. The program has focused on polymer-assisted separation of manure solids from the much larger percentage of liquid in manure. Other elements include producing marketable compost from the separated manure solids and using the separated effluent for land application at controlled rates and nutrient compositions on a cornfield. Most recently, the ISU Farm has been experimenting with odor control of the separated effluent in light of complaints from neighboring property owners about objectionable smells.
