I've got a several acres of open pasture with typical pasture grass and weeds established. This ground looks to have never been touched and is well established. What should my process be for planting? I've got a boom sprayer, tractor with harrow, and a 2 row corn/bean planter. I'm planning on planting corn and beans for the most part. Overall about 5 acres and plan on putting screens along the southern edge. Any help would be greatly appreciated.
