How many NFL fields are turf?

Answer 1

Currently, there are 18 NFL Stadiums with a grass, natural grass mix, or grass/artificial fiber mix. The move has been towards some type of artificial turf or mix for many teams for a number of reasons, but the most obvious is maintenance and upkeep.

As an example, the Ravens stadium originally had natural grass (smelled great too). However, much of the field was trashed during filming of the movie "The Replacements", and had to be completely replaced. Given that the stadium is also used for other events, it was more cost effective to move to artificial turf.

It's also much easier to maintain during the colder and rainier months during the regular season.

Still, I miss that smell of natural grass during Ravens home games.
