Without sufficient sunlight, the grass at Allegiant Stadium struggles to produce chlorophyll, leading to weakened blades and a higher susceptibility to disease. The enclosed structure also complicates climate control. Managing temperature and humidity levels is essential for the health of the turf. Too much humidity can create a breeding ground for fungi and bacteria, while excessive heat can cause stress and dehydration. Air circulation also needs to be carefully regulated to prevent stagnation and promote healthy growth. It’s a delicate balancing act, requiring constant monitoring and adjustments. The entire process aims to mimic a naturally occurring outdoor environment.
The Solution: A Retractable Field Tray System
To combat the challenges of growing grass indoors, the designers of Allegiant Stadium implemented a groundbreaking solution: a massive, retractable field tray. This incredible feat of engineering allows the entire grass field to be rolled out of the stadium and into the Nevada sunshine for a period of time, thus solving the lack of consistent sunlight and air circulation. The tray, weighing thousands of tons, glides smoothly on a series of rails, emerging from the stadium’s open end like a giant drawer. This system gives the grass at Allegiant Stadium the much-needed exposure to natural light, fresh air, and rain, essentially functioning as its own portable greenhouse.
The mechanics of the field tray are impressive. Powerful motors and a complex network of sensors work in unison to ensure a smooth and precise movement. The entire process of rolling the field in or out takes a few hours, and the system is designed to withstand various weather conditions. The tray is equipped with its own drainage system to prevent water accumulation and to protect the underlying structure. This innovation is a significant part of what makes maintaining high-quality grass at Allegiant Stadium possible.
The Variety of Grass Used
The success of the grass at Allegiant Stadium also hinges on the specific type of grass chosen for the field. Careful consideration was given to selecting a variety that could thrive in the unique environment and withstand the rigors of professional football.
The primary type of grass at Allegiant Stadium is a blend of hybrid Bermuda grass. Bermuda grass is known for its resilience, ability to tolerate high traffic, and its warm-season characteristics. It can withstand the wear and tear of football games and other events, while providing a stable playing surface for athletes.
Kentucky Bluegrass is also used in the blend. Kentucky Bluegrass is a cool-season grass. It is used as it can handle a more diverse set of temperatures. The selection of the grass at Allegiant Stadium involved extensive research and consultation with turf experts. Factors such as sunlight requirements, wear tolerance, disease resistance, and aesthetic appeal were all considered. The goal was to find a grass variety that could not only survive in the indoor environment but also perform at the highest level.
Maintenance and Constant Care
Maintaining the grass at Allegiant Stadium is a continuous process that requires a dedicated team and meticulous attention to detail. Every aspect of the grass’s health is carefully managed to ensure optimal performance and longevity.
Watering is a critical component of the maintenance routine.
