Wear has been recognised as a greater factor contributing to differences among turfgrass CGP 20712 than compaction alone. Carrow (1980) determined the relative compaction tolerance among species as follows: L. perenne, P. pratensis, and F. arundinacea. When both, wear and compaction, are applied turf species have been ranked: L. perenne, F. arundinacea and P. pratensis ( Park et al., 2010). L. perennewith high wear and compaction tolerance is one of the principal cool-season species for establishing sports turf ( Hoffman et al., 2010). In this research L. perenne was recognised as a species with the highest resistance to mechanical injuries. According to the present study P. pratensis showed better tolerance to wear generated by the BTS than F. arundinacea.Similar results were also obtained by Brosnan et al. (2005) who judged P. pratensisalong with L. perenneto be two commonly used turfgrass species in athletic fields grown in cool-season climates.
