The playing quality of turfgrass sports surfaces
Introduction Management of turfgrass sports areas should be directed primarily at producing a playing surface that encourages skilful play, maximises a player's enjoyment of the game in which he or she is partidpating and minimises the risk of injury (Baker and Canaway, 1993). As such, it is essential that we are able to assess the performance of sports surfaces in terms of quantitative measurements of factors such as ball bounce, ball roll, grip and surface hardness and have criteria by which measurements of playing quality can be interpreted. Testing playing quality should be an important component of research on sports turf areas as it is useful to be able to assess how different construction methods or management practices affect the sports player (Baker et al., 1988a; Lodge and Baker, 1991). In addition, performance spedfications are now being developed for the construction and particularly the maintenance of sports turf: again it is important that the playing quality and surface safety are included in such spedfications.
