Artificial turf was first invented in the early 1960s by an RTP research team headed by David Chaney. It was first used for field hockey in the 1970s.
Some artificial turfs have toxins which can cause cancer. Therefore, you must check materials of artificial grass before choosing which one you want.http://www.azluxurylawns.com/fake-grass-lawns

Field hockey playing surfaces vary depending on the level of play. The majority of games are played on grass or on synthetic turf surfaces, depending on who is running the game and the availabaility of the surfaces. Most stronger countries in the sport have turfs enough for everyone to use, while those who are not as strong, see the sport as a minor one only or who cannot normally afford a lot of them use grass or sometimes packed dirt surfaces. Most grades of field hockey above the junior-school level play on artificial surfaces like astroturf; for most national and international games, it is actually required that the surface be one of these turfs.
It is random. It is usually how many turfs you have there and how strong they are. If you have the most turfs and strongest turfs there you will become the capo
There "appears" to be a spray because in fact there is a spray. All games at the Beijing Olympics hockey tournament were played on the wet base artificial turf specially laid for the tournament. These turfs are covered with a small amount of water before (and somtimes redone at halftime of) each game, in order to help lessen the effect of injury on it and alow the ball to move quicker than if the turf was dry.
Hockey turfs have a carpet-like surface. By wetting the fields there is less chance of carpet burns or nasty scrapes occurring when skin scrapes the surface (such as when a player falls or scrapes knuckles).
