Claim 11:
12. An artificial turf system, comprising:
an artificial grass layer comprising a substrate and pile fibers upstanding from the substrate;
an infill layer, disposed on the substrate and interspersed between the pile fibers, the infill layer consisting of cork particulates; and
a cork particulate based infill mixture configured to prevent compaction of the cork particulates, comprising
cork particulates, and
smooth, hard granules,
wherein the cork particulates make up 51-70% of the infill mixture, and the granules make up 49-30% of the infill, and a percentage of the particulates is complementary to a percentage of the granules, and the granules have a mean size larger than a mean size of the cork particulates,
wherein the granules have a surface having a static frictional coefficient less than 0.5, a surface hardness is greater than Shore D 40, and a sphericity of greater than 0.9.
