Why does artificial turf used in soccer fields require careful consideration of infill material type and compaction level?

💡 Explanation

Artificial turf requires specific infill to mimic natural grass properties; therefore, the proper infill ensures optimal traction and reduces injury risk from slips and falls because it controls the interaction between cleats and the surface, rather than affecting UV resistance or cleaning.
