Get you a big current aerial photo of the area and see if you can tell of good feeding areas on the contiguous lands. Setting up near the line might produce. I wouldn't go too crazy with the fire. Briars and other weeds are very important food sources for the deer. Cutting down some of the less desirable hardwoods would promote better browse. Without seeing the area it is impossible to know all the answers. I would lean toward Lab Lab or Iron Clay Peas instead of soybeans. The deer can mow down an acre of soybeans in a couple of nights and won't come back as well.
