  • Patent number: 11021842
    Abstract: An artificial turf system includes a turf assembly having a turf backing and stands of artificial grass blades extending from the turf backing to form an artificial turf layer. Infill material is placed in between the blades of artificial grass and on top of the turf backing. The infill material has a composition of sand and organic particles. The infill material organic particles includes a plurality of wood particles where at least a portion of the wood particles define a length dimension oriented generally parallel to a grain structure of the wood particles. The length dimension is greater than a width or a thickness dimension and, in one example, may be in a range of about 0.5 mm to about 10 mm. The length dimension and one of the width or thickness dimensions may, in another example, define an aspect ratio within a range of 1:2 to 10:1.
