The Jeffrey Field Practice Complex, home to the Nittany Lions men’s and women’s soccer teams, was the latest and largest project in Hummer’s long relationship with Penn State. The 6-1/2 acre site is the latest field on the Penn State Campus to feature the Hummer Sand Grid Drainage System. An automatic, radio controlled irrigation system covers the entire site including both fields and practice grids. All 6-1/2 acres were covered by thick cut, big roll, Kentucky Bluegrass sod.
