Raw silica sand tends to have microscopic jagged edges. This is usually fine if the area is lightly used. However if the turf will see a lot of foot traffic, this could cause the sand to wear down the artificial grass blades over time. Sand infill can also be more abrasive if people were to fall and slide on the turf.

However, unless the soil is very sandy, it is generally not recommended to use a natural soil field (Natural Grass and Artificial Turf 9). This is because sand helps maintain nutrients and water within the soil, and so if the soil has no sand, these fields become “plagued with internal drainage problems” (“Types of Fields”).
