| Abstract/Contents: | "Concerns over concussions during sporting events are becoming more common and can cause detrimental effects to those affected. A new device, the Shockwave, offers hope to minimally disrupt the playing surface, but relieve soil compaction. However, data is lacking on how the Shockwave compares to relieving compacted soils compared with traditional aerification. The effects of hollow-tine, solid tine, and Shockwave aerification with a single pass and double pass were investigated and compared to an untreated control for surface hardness, surface stability, soil moisture, water infiltration, percent green cover, and bulk density on established Kentucky bluegrass [Poa pratensis] growing on a native soil maintained as an athletic field. Treatments were subjected to 25 simulated athletic traffic events using a Baldree traffic simulator in the fall of 2017 and 2018. In 2017, hollow-tine aerification treatments resulted in lower percent green cover at 35% as compared to the untreated control at 92% and Shockwave single pass at 88% green cover after 3 traffic events. The double pass of the Shockwave at 84% green cover also resulted in significantly lower percent cover after 4 traffic events compared to solid tine aerification at 93% cover. Significant differences existed for rotational resistance between treatments on all rating dates, with hollow tine treatments providing the least rotational resistance. Infiltration rates collected after simulated traffic was finished, and significant differences were determined at a 0.05 confidence interval. Hollow tine and single pass Shockwave aerification both resulted in higher infiltration rates, 5.08 cm and 3.46 cm per hour, than the control (2.046 cm/hr), two pass Shockwave (1.34 cm/hr) and solid tine aerification (2.39 cm/hr). No significant differences between treatments were reported in soil porosity or bulk density in year one. Shockwave aerification alone, does not appear to provide relief or negative impacts of soil compaction and surface hardness compared to traditional aerification methods after one year." |
