RE: food plot help
If you have an extension office or ag office nearby, they can do the soil tests for you, usually for free. We have an Iowa State University Extension office where students who are taking ag classes do that kind of stuff (Just as an option). The Biologic stuff is done basically the same way that you would do the beans or just about any other crop. First we mowed down the grasses then used a harrow, to get down to the recommended depth. Then its up to mother nature and your green thumb to get it growing and keep it growing. As to land size for planting beans, I believe its possible to grow it however big you want it, as long as it gets the water, sunlight and the balance of nutrients in the soil, it should work.
