The 2022 World Cup has come to an end. Let’s review some facts about the hi-tech turf (草皮) that Qatar had spent much of its energy on.
Qatar, a desert nation, had three main challenges: water, air and light. It got almost every condition going against it. The water used to irrigate (灌溉) the grass is low quality, mainly treated seawater. Because of the desert sun, Qatar’s stadiums were built for maximum shade—great for preventing heatstroke, but less ideal for photosynthesis (光合作用). Inside the nearly-closed stadiums, there’s very little air movement.
Qatar identified pitch (球场) quality as a particular issue and set up the Aspire Sport Turf Research and Development Centre to find the best types of grass for use in the harsh climate, testing 24 different varieties. Eventually, Atlas Turf’s grass was chosen as much for its appearance as its tolerance for the tough conditions Qatar faces.
The following pictures show some tech facts about the turf, which ensures a consistent and durable surface for the players in all weather conditions.
