We've got a couple small patches that were probably farmed to death before we owned them. The require as much input cost as everything else but yields are very hit-or-miss depending mostly on timely rainfall.

I planted some vetch/crimson clover/triticale on them in the fall, planning to terminate after good vetch growth but still in time to plant milo...either that, or just give them back to the Indians who were native here (mostly Foxes and Creeks I've heard).

But l got to thinking about just green manuring these fields for a couple years. Let the vetch grow to maturity and make seed. I've heard it will reseed decently well if the seed gets incorporated a bit.

What I wonder is how well it should disk. I know the crop mat should be mostly dry by the time I would disk it, so maybe can cut through it--maybe require a 2x disking, with either a tandem disk or a Horsch disk (would leave the surface smoother)
