=== Sports turf ===
{{see also|Turf management|Sand-based athletic fields}}
Grass playing fields, courses and pitches are the traditional playing surfaces for many [[sports]], including [[American football]], [[association football]], [[baseball]], [[cricket]], [[golf]], and [[Rugby football|rugby]]. Grass surfaces are also sometimes used for [[horse racing]] and [[tennis]]. Type of maintenance and species of grass used may be important factors for some sports, less critical for others. In some sports facilities, including indoor domes and other places where maintenance of a grass field would be difficult, grass may be replaced with [[artificial turf]], a synthetic grass-like substitute.<ref>{{Cite web|url=https://usatoday30.usatoday.com/sports/football/nfl/patriots/2006-11-14-testaverde-turf_x.htm|title=Pats sign Testaverde; Gillette Stadium's grass field replaced with Field Turf - USATODAY.com|website=usatoday30.usatoday.com|access-date=2019-12-10|archive-date=2021-03-08|archive-url=https://web.archive.org/web/20210308132244/https://usatoday30.usatoday.com/sports/football/nfl/patriots/2006-11-14-testaverde-turf_x.htm|url-status=live}}</ref>

In cricket, the pitch is the strip of carefully mowed and rolled grass where the bowler bowls. In the days leading up to the match it is repeatedly mowed and rolled to produce a very hard, flat surface for the ball to bounce off.<ref>{{cite web|last1=Tainton|first1=Neil|last2=van Deventer|first2=Pietr|title=Cricket pitches Principles and practice of pitch preparation|url=http://static.espncricinfo.com/db/ABOUT_CRICKET/PITCHES/PREP_OF_PITCHES.html#ANCHOR2|website=cricinfo|url-status=live|archive-url=https://web.archive.org/web/20170609100639/http://static.espncricinfo.com/db/ABOUT_CRICKET/PITCHES/PREP_OF_PITCHES.html#ANCHOR2|archive-date=2017-06-09}}</ref>

==== Golf ====
{{main|Golf course}}
Grass on golf courses is kept in three distinct conditions: that of the ''rough'', the ''fairway'', and the ''putting green''. Grass on the fairway is mown short and even, allowing the player to strike the ball cleanly. Playing from the rough is a disadvantage because the long grass may affect the flight of the ball. Grass on the putting green is the shortest and most even, ideally allowing the ball to roll smoothly over the surface. An entire industry revolves around the development and marketing of turf grass varieties.<ref>{{Cite book|last1=Stier|first1=John C.|url=https://books.google.com/books?id=UnnQDwAAQBAJ&pg=PA64|title=Turfgrass: Biology, Use, and Management|last2=Horgan|first2=Brian P.|last3=Bonos|first3=Stacy A.|date=2020-01-22|publisher=John Wiley & Sons|isbn=978-0-89118-613-7|language=en}}</ref>

==== Tennis ====
{{main|Grass court}}
In tennis, grass is grown on very hard-packed soil, and the bounce of a [[tennis ball]] may vary depending on the grass's health, how recently it has been mowed, and the wear and tear of recent play.{{citation needed|date=March 2016}} The surface is softer than [[hard courts]] and [[Clay court|clay]] (other tennis surfaces), so the ball bounces lower, and players must reach the ball faster resulting in a different style of play which may suit some players more than others.{{citation needed|date=March 2016}} Among the world's most prestigious court for grass tennis is Centre Court at [[Wimbledon, London]], which hosts the final of the annual [[Wimbledon Championships]] in England, one of the four [[Grand Slam (tennis)|Grand Slam]] tournaments.
