Answer by  David87 (112)

One cause of Grass dying in specific circles is Animal Urine, another cause would be a chemical contaminant, try removing any animals from your lawn, then call a lawn specialist

It could be that some animal is using your yard to urinate on. If not, try digging out that part of the grass and grow new grass from seeds and see if that takes care of the problem. If not go to the nursery, take a sample of your soil and ask them what you should do.

Most likely these circles are from dogs or other animals urinating on your lawn. The large concentration of nitrogen in animal urine burns and kills grass usually in a circular pattern.
