Poke a Hole in This: New Info on Aerification
Elizabeth Guertal, Ph.D.
Aerification is a frequently used tool for managing compaction and thatch in turfgrass. But in all honesty, there's not much
research that examines how aerification affects the soil and turfgrass. This webcast picks apart the results of work being done at
Auburn University – work that examines the effects of aerification frequency and aerification tine (solid vs. hollow, and various depths) on turf quality and soil compaction. Beth Guertal, Ph.D., covers the basics of physical soil properties, including bulk density, infiltration
and saturated hydraulic conductivity. Results from Auburn’s aerification research is presented, showing how aerification tine
selection can affect soil compaction.
