Abstract: Artificial turf for use with an artificial turf system, which may also include a base layer and a support layer. The artificial turf comprising a backing supporting pile tufts of between ¼″ to 4″ in length, in position on its upper surface. The backing may comprise a porous synthetic foam or backing sheet. A filler of particles shaped to have no sharp edges and of substantially equal size are interspersed over the backing and about the tufts up to at least half thick length. The artificial turf substantially retains its resiliency, porosity and equal density throughout.
