Imagine the world’s best soccer field: blade-perfect natural grass, fit for the likes of Lionel Messi and Vinicius Jr. and capable of withstanding nearly 40 days and 40 nights of top-level wear and tear.

Now imagine creating 16 such fields, for 16 stadiums each with its own climate: in Toronto; in Guadalajara; indoors and air-conditioned; outdoors in pouring rain or the blazing sun; some with artificial turf already in place. Now make the playing experience effectively identical from one to the next. Don’t disappoint Messi!

Where to begin?

Start, as FIFA did, by tapping John Sorochan, an expert in turf grass science and management at the University of Tennessee. Since 2018 Dr. Sorochan, in collaboration with John “Trey” Rogers at Michigan State University, has led the FIFA Pitch Research Project, a multimillion-dollar effort to level the playing fields of the 2026 World Cup to a flawless consistency. (Dr. Rogers, a former professor to Dr. Sorochan, is known to some as the Sodfather.)

Dr. Sorochan spoke to The Times a few days before the tournament opened on June 11. The fields were safely in place, and all that was left was “crossing the T’s and dotting the I’s,” he said. “The light at the end of the tunnel is no longer a bear holding a candle.”

This conversation has been edited for clarity and brevity.

Did you grow up playing soccer?

Yeah, I’m a lifelong fan and player. I grew up in Calgary, Alberta. My boys played and still do. I like Chelsea and the English Premier League. But I’ve become good friends with a lot of the field managers, so I’m an Arsenal fan, too.

 
 

Are you able to watch a match for the actual game, or is some part of your eye always assessing the pitch?

It’s a little of both. I’m always looking at the pitch in some way. If a player slips or falls, I’m like, What was the cause?

What drew you to turf science?

I started my academic career at the University of Calgary studying political science and geology. I was thinking I could be a lawyer in the oil and gas industry. But I didn’t like the idea of being inside all the time and doing a desk job. So I went and worked on a golf course, and I said, “Yeah, that’s what I want to do, I want to get into golf course construction and design.” I ended up transferring to Michigan State University, into the two-year turf program.

That’s when Michigan State got the project to try to figure out how to grow grass indoors for the 1994 World Cup in the Silver Dome. I’m, like, this is the best thing ever! I started working on it as a student; Trey Rogers was the professor in charge. That field was a portable field. They established it outside in hexagon modules, six inches deep, and then moved them into the Silver Dome, like a honeycomb. But it would be in there for 30 days, with very little light. How long could we make it last? I literally put on soccer cleats and ran back and forth simulating traffic on the plots.

After 30 days you could see the diamond-shaped wear, from the goals to the sidelines at the middle and back in, and where the assistant referees had been running up and down. That was the “Aha!” moment to me: I remember looking down from the roof of the Silver Dome, the wind blowing in my face, thinking, How do we make this better?

 
 

How was the final product received at the time?

We had a trial run in 1993, with the U.S. Cup in 1993. At the end of the tournament, Graham Taylor, the manager for England, said that the only people who wouldn’t like the pitch would be the bad players because they couldn’t blame the pitch. It was perfect.

Is it fair to say that expectations have changed since then?

If you watch an English Premier League from 1994, the players have mud on their uniforms, because it’s always cold and raining in England, and the goal mouth has that bird bath worn-out area in front. Those pitches weren’t great. Since then they’ve gotten grow lights, they’ve got hybrid reinforced pitches all constructed on a root zone of sand. Now at the end of the season they all look fantastic.

What do you like about grass?

The grasses are the most important of all plants. Why? I ask my students this in Intro to Turf and they’re like, “Golf.” They think I’m talking about turf grass. Really, come on! Wheat, corn, millet, rice — those are grasses and the staples of the world’s diet.

Of the thousands of grasses in the world, we identify maybe 25 to 30 as turf grasses. They’ve evolved with grazing animals. Turf grass has three things that separate it. It grows in a contiguous community, all among itself. It can tolerate traffic: You can play on it, walk on it, park on it. And it tolerates frequent defoliation or mowing; you can mow it every day. You can’t do that to rice, wheat, corn — if you mow those every day, they’ll stop growing and die.

The turf grasses each have their different utility. Some, like fine fescues, are on some cool-season golf courses, but I wouldn’t want to play a soccer game on it; it’s not going to wear or recover well. Bermuda grass is big for sports fields, because it spreads through rhizomes and stolons — horizontal stems. These help anchor the turf and knit it together, so it has excellent wear tolerance and recuperative potential. A lot of breeding has focused on things like drought resistance and reducing fertilizers. And then there’s pest management — controlling weeds, diseases and insects. The other pest is the athlete, right?

 
 

What have you learned about that particular pest?

A lot of turf research has been about the traffic tolerance and wear tolerance of different grass varieties. For golf we always did a lot of ball-to-surface interactions — how the ball rolls on the greens, green speeds, things like that.

I started asking, How does the athlete interact with the surface? Eventually we developed the Flex. It’s a machine that can strike the turf with a foot — a 3-D printed foot with a cleat — coming in at an angle. It’s given us a lot of data. We can measure many parameters of recoil, the energy being pushed back on the foot. We can measure traction — how many millimeters the foot displaces the surface.

Because we put sensors and load cells throughout the foot, we know the load that the athlete is feeling, too. We can strike with different masses — little Maryanne playing soccer at 35 pounds to Bubba playing American football at 350 pounds. We can measure how well a natural grass surface complies with regulations, and we can compare one pitch to another.

I was just thinking of it from the concept of a game. You drop the ball to your left back and he switches it to the midfielder on the other side. When that ball’s coming in, you want that ball to hit and skip and not bounce up above their knees, so they can trap the ball and make their move. If it bounces too high, they have to trap it with their chest — then the defender’s on them and maybe takes the ball away.

The game of soccer has changed significantly over the last three decades; it’s faster, more stylish. How much has the modern field — smooth as a billiard surface, consistent, predictable — played a part?

So much is different. The athletes have wearables that track their vitals; they’re health conscious, more fit. They wear cleats that improve their performance. But yeah, having a uniform pitch that’s not worn out, with a ball bouncing in mud. …

The Spanish team that won the 2010 World Cup in South Africa might have been the most beautiful team to watch. I got goose bumps. They didn’t score a lot of goals, but man, they controlled the game with their technical skill and passing. The surface made that team better, because the ball was on the surface so much of the time.

Don't think Scotland were great and a draw was probably a fairer result, but winning was all that matters. Very decent chance of getting to the knockouts now.

Good luck to them and I hope the sweaties enjoy their time but as an England fan I wanna see a proper team wipe the floor with them in the knockouts.

3rd place in this group going through almost certainly gets the Germans, 2nd most likely the Netherlands (group F winners), Group winners is group F runners up so likely Japan. Finish 3rd and a pummeling in Ro32 is pretty likely

Gannon Doak was a standout for me last night, looks very assured and lively on the ball. I was too busy with our own misery last season to pay much attention to the Prem, but am I right his appearances were limited by injury?

If he stays fit he could have a big breakout season for Bournemouth next year. Looks class.

TV Coverage again patronising towards Scots win over the mighty Haiti, annoys me every time the other home nation qualifies they get sickly southern presenter expecting us to back Scotland. Sod that... would you expect a Leicester fan cheer on Cov in the premier league, Celtic fan cheer on Rangers in europe?
