As the countdown to the 2026 FIFA World Cup continues, the University of Tennessee at Knoxville is at the forefront of groundbreaking turf research, aiming to ensure that the quality of playing surfaces is optimal across all venues. With 16 stadiums set to host matches in the United States, Canada, and Mexico, the expertise of John Sorochan, a professor of turfgrass science and management, is being leveraged in collaboration with FIFA to maintain top-notch turf conditions for all 104 games.
Currently in the critical final stages of their research, Sorochan and his team have previously implemented their findings during the Club World Cup earlier this year. An exclusive tour at the East Tennessee AgResearch and Education Center showcased the advanced covered facility built to simulate the conditions of five domed stadiums expected to host the 2025 FIFA World Cup. The innovative turf solution incorporates cutting-edge technology, including the use of LED grow lights to replicate ideal growing conditions. These lights are carefully calibrated, shining for about 12 hours a day, and utilize different color wavelengths to promote various growth patterns in the grass.
The sod developed at UT is particularly noteworthy; grown on plastic to encourage robust root development, it allows for expedited installation in stadiums. This method ensures that the grass can be rolled up and transported without significant damage. The incorporation of artificial fibers—making up about 5% of the sod—provides additional stability, allowing for quick assembly and disassembly within a 12-hour timeframe.
Moreover, Sorochan’s substantial contributions extend beyond turf quality. He collaborated with research associate Kyley Dickson to create the fLEX machine, born out of a previous experience where an NFL game in Mexico City had to be relocated due to unsafe turf conditions. This machine simulates foot strikes to evaluate the turf surface, ensuring it meets the standard required for athlete safety. Sorochan’s innovation has now garnered interest not just from FIFA, but also several NFL teams, illustrating the versatility of his technology.

While the primary focus has been on warm-season Bermuda grass, UT is also employing techniques to overseed with cool-season ryegrass, enhancing stability similar to the support provided by artificial fibers. The combination of these grasses will be paramount during the World Cup, particularly as varying climates across playing venues necessitate diverse turf requirements.
Dillon McCallum, the lead technician for the FIFA research, reflects on how his ambitions aligned with this prestigious project, originally ignited by a chance encounter during his college years. His journey to UT for a master’s degree has culminated in hands-on experience contributing to the World Cup’s successful execution.
Sorochan’s research emphasizes the importance of consistent playing surfaces throughout the tournament, ensuring that players experience the same conditions regardless of the stadium. This commitment not only enhances player safety but also upholds the integrity of the competition, minimizing external variables that could impact performance.
As FIFA prepares for the World Cup, the collaborative efforts of the University of Tennessee and their cutting-edge turf solutions highlight a commitment to excellence in sports that transcends borders. With ongoing plans for future projects together, this partnership is set to pave the way for more advancements in sports turf management.
