>>2552319Cover crops, as already suggested are a good idea. Annual legumes and a grain or biomass crop would do a lot to help the soil.
Alternatively just broadcast a pasture mix that's well-adapted to your area. Even the STUN method of orchard that mark shepard does might work well for you--basically just toss a ton of seedling fruit trees into the ground as cheaply as you can, with the understanding that most will die, but the ones that live will generally be very hardy and well-adapted.
