Depending on the size of the area you need some farmer with a tiller or a plow. turn it, plant it to a cover crop, ( my father planted a couple of acres of buckwheat to start a vegetable garden to feed us) Plow it under, plant rye in the Fall, turn that under in the Spring and it might be tillable. Of course a few loads of manure first and mixed cover crops with legumes or I guess people plant deep rooted radishes would help. I keep dreaming about starting some new, small, daylily beds but arthritis will stop me from spading, one or two years is to long to plant when your eighty so I think I'll just go fishing.
