Claim 0:
1. A method for avoiding compaction of cork particulates in an infill layer comprising:
mixing an infill comprising cork particulates and smooth hard granules, wherein the cork particulates make up 51-70% of the infill , 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
distributing the infill in an artificial turf system having a substrate and a plurality of pile fibers extending from the substrate, wherein the step of distributing the infill includes creating an infill layer over the substrate so that the pile fibers extend above the infill layer,
wherein a surface of the granules has a static frictional coefficient less than 0.5 and a surface hardness greater than Shore D 40, wherein the granules have a mean size which is larger than the mean particulate size of the cork particulates, and wherein the granules have a sphericity of greater than 0.9.
