When the world tunes in for the 2026 FIFA World Cup, the focus will be on goals, stars and national pride. But beneath every pass, sprint and slide tackle lies something just as critical to performance: the grass.
Sixteen stadiums. Three countries. Dozens of matches played across dramatically different climates. And one non-negotiable requirement: every game must be played on natural grass that performs the same, no matter the location.
Delivering that level of consistency has become one of the most complex turfgrass efforts ever attempted. At the center of it is a collaboration involving Michigan State University’s Turfgrass Management Program, the University of Tennessee, Knoxville and FIFA.
From East Lansing to the World Stage
The project is led in part by John “Trey” Rogers III, a turfgrass researcher at Michigan State University who has spent much of his career studying how playing surfaces respond to athletic movement.
This is not his first World Cup. In 1994, Rogers helped develop a portable grass system that allowed natural turf to be installed inside the Pontiac Silverdome. At the time, it was a novel concept. Today, variations of that idea are used around the world.
The 2026 tournament expands that concept on a much larger scale. Instead of one experimental field, the challenge is to deliver consistent playing conditions across 16 venues, many of which were built for artificial turf.
Since 2021, researchers from Michigan State and the University of Tennessee have worked under a FIFA-supported initiative to address those challenges. Their work has focused on how to build fields that meet strict performance standards while adapting to different environments.
Creating a Consistent Playing Experience
One of the biggest questions early in the process was how to ensure that a match in Seattle would feel the same as one in Mexico City or Miami.
Each location presents its own conditions. Northern sites deal with cooler weather and less intense sunlight. Southern venues face heat and humidity. Some stadiums are open-air, while others are enclosed and rely on artificial lighting.
Despite those differences, the playing surface must feel uniform so players do not need to adjust their footing, timing or expectations from one match to the next.
To achieve that, researchers studied fields across multiple leagues and tested how surfaces respond to real-world movement. Specialized equipment was used to simulate the impact of a player’s foot, measuring factors such as traction, firmness and energy return.
These tests helped define performance targets. From there, the team developed turf systems designed to meet those targets across a range of environments.
At the core of the system is a carefully engineered mix of Kentucky bluegrass and perennial ryegrass, or Bermudagrass in warmer climates. Each species brings specific strengths. Kentucky bluegrass offers durability and recovery, while perennial ryegrass provides faster germination and early stability. Bermudagrass delivers heat tolerance and resilience in southern environments.
Rethinking How Grass Is Grown
One of the biggest breakthroughs in the project came from rethinking how sod is produced from the ground up.
In traditional systems, sod is grown in native soil and harvested by cutting through the roots. That process shocks the plant and can delay recovery for weeks — time that simply isn’t available when a field may host matches within days of installation.
Researchers developed a system that grows sod in a thin sand layer over plastic. Instead of growing downward, roots spread laterally, forming a dense, interwoven mat that remains intact during harvest.
This allows the turf to be installed and perform almost immediately. However, the system introduced new challenges. With a shallow sand layer, heavy rain during early growth stages can wash material away, particularly with slower-establishing species.
To counter that, researchers adjusted the seed blend to include faster-establishing grasses, creating a more stable surface early in development.
Building a Stronger Playing Surface
Even with a stronger root system, the demands of a World Cup schedule push natural grass to its limits. Multiple matches, training sessions and events within a short window require a surface that can withstand repeated stress.
To improve durability, the project uses hybrid turf systems that combine natural grass with synthetic fibers. These fibers integrate with the root system and help stabilize the surface under heavy use.
Researchers tested several hybrid systems to ensure they met performance standards for ball movement, traction and surface firmness across all venues.
Turning Football Stadiums into Soccer Fields
Many host stadiums were not designed for natural grass. To adapt, venues have added drainage, ventilation and airflow systems to support turf performance. In enclosed stadiums, high-powered grow lights are used to replicate sunlight and maintain grass health over several weeks. Some stadiums also adjust roof operations and airflow to regulate temperature and humidity.
A Logistics Operation Measured in Minutes
Once the grass is grown, it must reach each stadium in peak condition. Sod is harvested in large strips, rolled and transported in refrigerated trucks to keep it dormant during transit.
Because the sod is grown on plastic with an intact root system, it can withstand longer transport times. This allows grass to be shipped across regions when needed, including from cooler climates to closed stadiums that require low-light-tolerant species.
At the stadium, crews work quickly to install the field, aligning and pressing sections together to create a uniform surface. Timing is critical to ensure the field is stable and ready for play.
Testing in Real Conditions
Before the World Cup begins, these systems are being tested through a series of events. Stadiums like SoFi in Los Angeles have already installed prototype fields for events such as the CONCACAF Nations League, using them to see how the grass responds to play, weather and maintenance routines.
Ground crews and researchers monitor the surface closely, tracking how it responds to use, weather and maintenance practices. Adjustments are made based on what they observe. Lighting schedules, watering routines and mowing practices are all refined as part of the process. The goal is to identify and address any issues before the tournament begins.
A Project Still in Motion
Even with years of preparation, uncertainty remains. No tournament has attempted this level of consistency across so many venues.
Teams have built redundancy into the system, with backup plans and additional materials in place as conditions evolve.
The Quiet Foundation of the Tournament
For most fans, the grass will go unnoticed. But each field represents years of research, coordination and execution. Scientists, grounds crews and logistics teams have worked together to deliver a surface that supports the game without drawing attention to itself. If everything goes as planned, no one will be talking about the grass at all.
