I broadcast my corn this year(with an atv) with very good results.Over-seeded with soybeans.Turned out very good.We normaly drill the corn but every-one was late due to the wet spring,and very busy with their own plantings.
I spray with round-up(ready corn and soybeans) worked well.
I plow,till and drag after planting.I have doing this for eight years and seems to work well in our conditions.
