The surface is the product of extensive research, strategic selection of hybrid bermudagrass, innovative maintenance practices, and ongoing efforts to overcome the environmental limitations of an indoor-outdoor venue. Let’s delve into the world of stadium turf management and uncover the secrets behind this remarkable field.
The Unique Challenges of Growing Natural Grass Indoors
The choice to install natural grass in a stadium with a retractable roof is a decision that comes with a unique set of hurdles. Unlike outdoor fields that bask in the consistent warmth and sunlight, the Mercedes-Benz Stadium’s grass exists in a controlled environment that can swing between sunlight and shadow, ventilation and stagnation.
One of the most significant issues is limited sunlight. Natural grass relies on sunlight for photosynthesis, the process by which it converts light energy into the sugars it needs to grow. When the roof is closed, the grass is deprived of this essential resource, leading to a host of potential problems. Without sufficient sunlight, the grass becomes weaker, less resilient, and more susceptible to diseases and pests. Its ability to recover from the wear and tear of games and events is also significantly diminished.
Air circulation also presents a challenge. In open-air stadiums, natural breezes help to regulate temperature and humidity, preventing the build-up of stagnant air that can foster mold and fungal growth. In a stadium like Mercedes-Benz, airflow must be carefully managed to ensure that the grass receives adequate ventilation. Without proper air circulation, the field becomes more prone to diseases, and the overall health of the turf suffers.
The sheer volume of use the field receives also poses a constant challenge. From Atlanta Falcons football games to Atlanta United soccer matches to concerts and other events, the Mercedes-Benz Stadium’s grass is subjected to intense wear and tear. This requires careful planning and execution of maintenance strategies to ensure that the field remains playable and safe.
Finally, climate control is a critical factor in maintaining a healthy grass surface. Temperature and humidity levels must be carefully regulated to create an optimal environment for grass growth. This requires a sophisticated system of heating, cooling, and ventilation that can respond to changing weather conditions and event schedules.
The Grass of Choice: Hybrid Bermudagrass
To combat the challenges of indoor-outdoor grass cultivation, the Mercedes-Benz Stadium relies on the resilience and adaptability of hybrid bermudagrass. Tifway four nineteen has been the choice, though varieties like Tahoma thirty-one may offer improvements that are being explored.
Tifway four nineteen bermudagrass is known for its fine texture, dense growth habit, and excellent wear tolerance. Its ability to withstand heavy traffic makes it an ideal choice for a stadium field that hosts numerous events. Additionally, the bermudagrass demonstrates strong drought tolerance, which is essential for managing water usage in a stadium environment. Its ability to recover quickly from damage is equally important, allowing the field to bounce back between events.
While other grass varieties were considered, bermudagrass’s unique combination of traits made it the clear winner. Advancements in bermudagrass genetics continue to yield new cultivars with even greater resilience and improved performance, ensuring that the stadium’s field remains at the cutting edge of turfgrass technology.
The Art and Science of Turf Management
Maintaining a healthy grass surface under the unique conditions of the Mercedes-Benz Stadium requires a comprehensive approach to turf management that combines traditional practices with cutting-edge technology.
One of the most important aspects of this is the use of artificial grow lights. These lights supplement the limited sunlight that the grass receives, providing the energy it needs to carry out photosynthesis. The stadium uses a combination of LED and high-pressure sodium (HPS) lights, which are strategically positioned to maximize light exposure across the field. The lighting schedules and intensity are carefully calibrated based on factors such as the time of year, the weather conditions, and the amount of natural sunlight available.
The stadium’s ventilation system also plays a crucial role in maintaining the grass’s health. The system is designed to circulate air throughout the field, preventing the build-up of stagnant air and promoting even temperature distribution. This helps to reduce the risk of diseases and pests and ensures that the grass receives the oxygen it needs to thrive.
Watering and fertilization are also carefully managed to ensure that the grass receives the nutrients it needs. The stadium employs an efficient irrigation system that delivers water directly to the roots of the grass, minimizing water waste. Soil testing and analysis are conducted regularly to determine the precise nutrient requirements of the grass, and fertilizers are applied accordingly. Water conservation efforts are also prioritized, and the stadium uses recycled water whenever possible.
Aeration and topdressing are two other important practices that are used to maintain soil health and drainage. Aeration involves creating small holes in the soil to improve air circulation and water infiltration. Topdressing involves applying a thin layer of sand or other material to the surface of the field to smooth out irregularities and promote healthy root growth.
Pest and disease management is also a critical component of the turf management program. The stadium employs an integrated pest management (IPM) strategy, which focuses on preventing pest and disease problems before they occur. This involves careful monitoring of the field, the use of natural pest control methods, and the judicious application of pesticides only when necessary.
The condition of the grass is constantly monitored using a variety of sensors and data analysis tools. This allows the turf management team to track key metrics such as soil moisture, temperature, and nutrient levels, and to make adjustments to the maintenance program as needed. Expert consultation is also sought from leading turfgrass specialists to ensure that the stadium’s field remains in top condition.
The maintenance team also has renovation plans for regular field replacement of the turf. Specific equipment, like the specialized mowing tractors, is used in grass maintenance to ensure a cut is uniform and does not damage the plant in anyway.
