I did a bale graze the last drought and it worked really good. Just set your bales out in an area that needs nutrients. I picked a rocky hillside that had been overgrazed. I set enough bales out for a month at first (finally I just set enough out to last until spring). Space them about 20' apart. I only fed one bale at a time, but if you had enough cows you may need more. I used a light bale ring (cheap one) that is easy to roll. Fence it with temporary electric fence, same way you would a temporary paddock. Just move the fence and bale ring when they are ready for the next bale. If the ground is dry, they won't rip it up. Keep a back fence up so they can't back graze on the little grass there. I never started the tractor the rest of that winter, except to push a little snow off the driveway. I fed on about 4 acres. It went from my least productive to most productive land. I did put clover and grass seed down as the cows worked their way across it - kind of let them work it in. The only area I had any problems in was the part I grazed when the drought broke and it was muddy. They tore that up pretty good. That is what I would do.
