Too late for your original question, but here's a powerline in Henry County VA that I planted in late April with Hancock Spring and Summer mix. The sample came back with ph-5.0, fertilize at 50/75/75 lbs/acre NPK.

I decided to plant it because the power company came through with a forestry mulcher in February and leveled it. I don't have a lot of equipment so all we did was pick up the chunks wood and rocks and spray it in early April. Then in late April I mowed it and ran a tooth drag over it a bunch, liming, fertilizing and seeding along the way. By Memorial Day it was up about a foot. By July 4th it was up about 4-5 feet and the millet and sorghum was topping out. This past weekend the millet is browning up and the sunflowers are about 4-5 feet tall. The deer and turkeys are all over it. Labor day weekend I'm going to broadcast Hancock Fall and Winter mix into it and mow/fertilize. Then next spring I'm going to try a perennial grazing mix.
