Traction is directly related to frictional force. Force = mu * N, where mu is the coefficient of friction and N is the normal force (force directed directly away from a surface that something with friction is on). Notice the lack of area in that equation? Yep, there's a reason for that. Namely, surface area doesn't matter.

There's been discussion of this issue already, some years ago. Look it up.

And, the only way to increase mu is to increase the coefficient of friction. You can a) change materials or b) dig one material into the other. If you try doing b) to an HDPE section of the field, I'll call a rules violation, assuming there is a "no damaging the field" rule again.
