I have a new project, and I believe my biggest problem is the severe compaction of the dirt. It is in Oklahoma, and the grass is Bermuda, but it is very, very sparse due to the intense wear/traffic. It is around a school and is walked on hundreds of times each and every day. It is so rock hard, that I am not sure an aerator would even work. The ground is also very unlevel. What are my best options? Thank you for your time.
