Turf grass

特許 係属中 Grass is important in many sports, notably with those played on fields such as American football, Association football, baseball, cricket, and rugby. In some sports facilities, including indoor domes and other places where maintenance of a grass field would be difficult, grass may be replaced with artificial turf, a synthetic grass-like substitute. Sports such as golf, tennis and cricket are particularly dependent on the quality of the grass on which the sport is played.
