That's the way top soil looks here in Ohio, Like when a home is built on a lot, A good 4 inches is scraped & put into a pile, To use after construction, To get the final grade, Once the lot gets leveled out, and a rockhound on it, It will look much better, if you have some compost to get rid of, get it out there before it is graded level, The tooth bucket will till it in, as it gets leveled,

You will be amazed how some ruff soil produces a nice lawn,
Usually the last house built in a allotment gets all the scraps,
