For your purposes that stuff is useless.

Planting ryegrass will do a lot better job of turning crap dirt into something useable and adding OM to the soil. A lot of folks hate on ryegrass around here, but it's turned some of my bare dirt landings, hard as a rock and red dirt, into places where turkey and deer eat near daily over just a couple of years. After the rye grows and dies back it allows native plants and grasses to start growing again, then you can get more creative with what you can plant in that area. It'll have some rye in it for a while likely, but that's ok IMO.
