"Thatched layers also help the taller blades stay upright and bounce back after foot traffic." Keeping the turf’s surface clean prevents organic matter from building up and affecting its drainage.

The turf can be sprayed with water to produce a short-lived evaporative cooling effect, but the thin layer of liquid on the turf evaporates quickly, plus it makes the playing surface slippery ...

In one experiment, a group of MSU students pack different levels of sand between asphalt and a layer of turf grass. They then drop a soccer ball on the grass and measure the sound of its bounce.

The researchers used grass’ natural water absorption as inspiration and created their own turf with an open water storage layer tucked directly underneath the surface turf and shock pad.
