Bald patches on lawn?

2015-05-01T05:02:13Z

I have a couple of patches on my lawn where not matter what I do, the grass dies. These are circles about 2' across. I have laid sod and seed on these patches over the years, and whatever I do, the grass I put there eventually dies. I wonder if there is some parasite might be living in that spot. Any thoughts?

I live in central Texas.
