I don't think my soil prep quite meets your standards . It was tilled as deep as a walk behind can till, debris was removed and then raked. My soil sampler makes it down to around 8" before getting tough to insert. Installed the sod June of 2009. I'll pull up my last soil report.

Well, that is better than most. Most installers consider no soil prep or a shallow layer of topsoil as "proper" prep. Don't under estimate the importance of SOM, it can make or break a lawn.

Go pull some cores in the bad areas, then some in good areas, take some close up pics of both, then post.

You have ruled out disease and/or pests ... right? What are your cultural practices? Fertilizing? Pesticides? Turf type (looks like it might be fescue)? Have you done any soil moisture mapping?

Maybe the neighbor's cat likes to pee in that central spot.

Don't get me started on cats! However, I can say that coyotes have now been documented in every county in NC

That's the answer... more water!

If your spray heads are aligned on center you won't get a dry spot. If you do, it may be some sort of pathogen that requires a licensed pesticide applicator, more water and/or fertilizer will make it worse.

From the pic though, looks like you are missing, I think someone mentioned a rotater in the center.

Any animals peeing in that yard?
That could cause spots in the yard.
Hmmm, I see that was already covered.
Time for more coffee.
