When We plant any Soybeans we usually go to a local Feed Store/MFA or other Farm Supply Store and just get the plain cleaned seed or as mentioned the Round-up ready Soybeans that cost more and You can't Replant or sell.
If Your not planting a decent size Soybean field (1/2 to 1 acre or larger) and there's plenty of Deer around and that's the only nearby food source when the Beans sprout and start looking so wonderful...the Deer will eat them down to nothing and You've wasted Your time & money!
I like planting a Variety of Plants...those that take heavy browsing and bounce back are Your better choices.Those I reccomend are the following:
Wheat
Oats
Turnips
Raddishes
Brassicas & Rape (more green leafs less bulb than turnips)
Sugar Beets
Sunflowers
Clover
Milo
