RE: weed control
Apply Round-Up in the spring then let the field sit 10 days to two weeks (depending on amount of plant activity) before youwork it (you want the Round-Up to make it through the entire root system). Round-Up will kill anything that is green unless it has been genetically modified. I strongly suggest you do NOT plant genetically modified seed. It may take a few years, but the Round-Up and your crop will help to cut out the weeds. Be sure to do a crop rotation. Planting the same vegitation year after year on the same soilcan result in disease.
