I'm getting ready to plant some RR alfalfa this spring, and thought I'd ask your advice on the brand. Right now I'm looking at WL 355.RR. The dealer wants $345 per 40 lb bag. I've seen other brands, Ameristand, selling for around $350 for 50 lbs. The research I've done tends to point to WL as the superior seed. Any advice? I Live in NE Kansas.
