Pardon the expression, but I've f***ed up my soil badly! I'm trying to reclaim about 1/2 an acre from the wilderness that is my yard. We had a pretty severe infestation of benghal dayflower. It's like a giant net just under the surface of the soil. Utilizing more brashness than brains, I rented a bobcat with a front end loader and ripped that stuff out of the ground whilst doing a bit of grading. It would've worked fine, but for the moisture in the soil. Like much of Georgia, we have rocky, clay soil. It's not totally devoid of organic matter and was mostly friable. Before I drove all over it with a heavy machine. Now it's completely dry and packed, really packed! I can't get a tiller (honda fc600) to touch it. I can just get a shovel into it, but I don't have the fortitude or time to hand cultivate 1/2 an acre. Any advice? Bigger tiller? Mule and plow? Tac nuke?
