What is the artificial grasses?
Artificial grasses?are a surface of?synthetic fibresmade to look like natural?grass. It is most often used in arenas for?sports?that were originally or are normally played on grass. However, it is now being used on residential lawns and commercial applications as well. The main reason is maintenance—artificial turf stands up to heavy use, such as in sports, and requires no?irrigation?or trimming. Domed, covered, and partially covered stadiums may require artificial turf because of the difficulty of getting grass enough sunlight to stay healthy.
Artificial grasses were later installed in other new cookie-cutter stadiums?such as?Pittsburgh's three river stadiums, ?Philadelphia's veterans stadiums, and?so on. Early AstroTurf baseball fields used the traditional all-dirt path, but in the early 1970s, teams began using the "base cutout" layout on the diamond, with the only dirt being on the pitcher's mound, batter's circle, and in a "sliding box" around each base. With this layout, a painted arc would indicate where the edge of the outfield grass would normally be, to assist fielders in positioning themselves properly.
