Astroturf is a type of artificial turf used to mimic grass. While not the same as grass, the cost of laying AstroTurf, especially in indoor stadiums, is much cheaper then laying natural turf and maintaining it.
AstroTurf is typically made out of synthetic fibers to make it look as though it's real grass. AstroTurf is normally used in sports arena's and sometimes on commercial land also.
