If you're doing it for a foodplot, you are just fine in the ballpark - even depending on how many beans = a pound. For deer, I tend to go on the high end of things. I'll even double plant them right along the timber OR in a secluded part where the deer hammer them. Usually, most folks are putting 75 lbs (on avg depending on bean) to acre. I've got em at about 100 lbs on my place cause the deer really do thin them for me. U sure have more leeway to overplant beans than you do corn. Get after em with P&K (and Lime if needed) and make sure you are planting enough acres & you'll be good.
