An infilled artificial turf surface [] includes a particulate infill [] with at least a top layer [] that comprises a mixture of Black walnut shell particles [] and English walnut shell particles [the walnut shell particles [having been treated so as to eliminate or substantially remove tree nut allergens that are known to activate allergies in some humans. Preferably, treatment occurs via heat treatment in a rotary furnace, which also rounds and smoothes the particles [Particularly if used in the top layer [of a particulate infill [of an artificial turf surface [the shape and size and proportion of the Black walnut shell particles [and the English walnut shell particles [provide stability for the resulting turf surface [while also being able to absorb water applied thereto, thereby to hold moisture and to provide evaporative cooling of the artificial turf surface [for up to about five hours.
