Abstract/Contents:"Athletic fields should provide a safe, stable surface that resists divoting. A divot on an athletic field can be described as a piece of turf partially or completely gouged out of surrounding turf by studded footwear. Divoting often results in poor footing, which can compromise the playability and safety of the playing surface. Few studies have evaluated divot resistance on athletic fields. Trinexapac-ethyl (TE) has been found to increase tiller density and affect rooting of Kentucky bluegrass (Poa pratensis L.). These effects may increase the divot resistance of a turfgrass stand. From 2006-2008, studies were conducted on both a USGA sand-based rootzone and a silt loam soil to evaluate two TE application regimes (May-July and May-Oct) and springtime cultivation on the divot resistance of nine Kentucky bluegrass cultivars under various levels of simulated traffic. Traffic was applied using a Brinkman Traffic Simulator. Divots were created following the final traffic application in November using the PENNSYLVANIASWING device, which consists of a weighed pendulum with a golf club head attached to one end. Divot length was used to indicate differences in divot resistance. TE applied from May-July was the most effective treatment, reducing divot length compared to the control by 15% on the sand-based rootzone and by 10% on the silt loam soil. TE applied from May-October and the cultivation treatment each showed some evidence of improving divot resistance compared to the control, but differences were smaller than those observed with the May-July TE application regime."
