Organic infill for artificial turf fields

Abstract

The present invention relates to organic infill for artificial turf fields. The organic infill includes at least one layer of particles having olive pit particles. At least 1% of the olive pit particles are particles that have a sieve size of 50 or smaller sized particles. The at least one layer can further include olive pit particles in other sieve ranges, sand, or both, and be intermixed in the at least one layer. The organic infill can also include a layer of sand overlaying a backing of an artificial turf field. The at least one layer overlays on the sand layer. The organic infill can further include a layer of olive pit particles or extruded composite. The layer includes olive pit particles having a sieve range different from the sieve range in the at least one layer. The layer overlays on the at least one layer.
