Those are some good looking beans. I like your plan to mix maturity dates as insurance against frost while also giving you some green leaves into bow season. What organic matter % does your soybean plot have?
Have any luck with your overseeding brassicas or rye in your beans? I broadcast brassicas in oat stubble in july and cultipacked and have some nice looking brassicas. I broadcast some brassicas into neighboring soybeans growing on 30" rows without any cultipacking and I didn't have much luck. I'm just curious to find out if anyone else has any luck overseeding brassicas in beans or if I'm just throwing away seeds. My soil is fairly sandy, so maybe that hurt my broadcasting chances a bit.
