Caption: John Stier, associate professor of horticulture (L), Jim Park, professor of civil and environmental engineering (center) and Bob Lisi, graduate student in civil and environmental engineering (R), hold a bucket of shredded tire chips at the University Ridge golf course, adjacent to the O.J. Noer Turfgrass Research Facility where they have conducted research on the impact of fertilizers and pesticides. The researchers found that shredded tires placed beneath golf course greens can absorb excess nitrates and other chemicals from fertilizers.
