Determining wear tolerance of turfgrass species for athletic fields in the transition zone
A study to evaluate the performance of four different turfgrass varieties under
simulated athletic field traffic in the transition zone was conducted in Tennessee and
Arkansas. ‘Thermal Blue’ hybrid bluegrass (Poa arachnifera Torr. x P. pratensis L.)
has been introduced as a bluegrass variety bred for increased heat and drought tolerance.
This variety provides a possible alternative to bermudagrass varieties in transition zone
athletic fields. ‘Thermal Blue’ was compared to common bermudagrass (Cynodon
dactylon L. Pers.) varieties ‘Riviera’ and ‘Quickstand’ and the hybrid bermudagrass (C.
dactylon L. Pers. x C. transvaalensis Burt-Davy) variety ‘Tifway’. Each turfgrass species
was tested with and without a 2 cm crumb rubber topdressing application in their first
year of establishment. The Cady Traffic Simulator was used to simulate athletic field
traffic on each plot. Low and high traffic conditions were obtained by applying 1 and 3
traffic applications, respectively week
-1. ‘HTBG’ proved to be acceptable for use in
transition zone athletic fields. ‘Riviera’ showed comparable wear tolerance to ‘Tifway’.
‘Quickstand’ showed the lowest wear tolerance of the varieties tested. Crumb rubber
topdressing resulted in a significant increase in turfgrass wear tolerance, and a decrease in
surface hardness, soil bulk density, and shear resistance.
Ground-Penetrating Radar (GPR) was tested to see if it could be used to detect soil
compaction incidences in athletic field environments. GPR readings were compared to
Clegg Impact Soil Tester (Clegg hammer) readings taken from Shields-Watkins Field in
Neyland Stadium, Knoxville, Tenn. Visual comparisons between the two methods
showed that maps produced using GPR were comparable to those produced with the
Clegg hammer. GPR can possibly be a method for predicting compaction in athletic field
