Consider fertilizing the plants that are already there. Deer have a sixth sense about which plants have luxuriant growth and higher nutritional value. You can pack in a couple of bags of regular 10-10-10 and fertilize a patch of honeysuckle or mixed thicket of green briars, honeysuckle and briars. we did this on public game lands and within one season our fertilized patches became thick, green and overgrown. Deer were drawn to them and they provided food long after other patches had died back in the winter.
Also consider fertilizing trees. Oaks, beeches, persimmons, and sweet locust trees all benefit from fertilizer and will bear thicker nut and fruit crops after fertilization.
We regularly fertilize a huge white oak tree on my current hunting land and the honeysuckle, green briar thickets in the creek bottom below it. I can honestly say it has attracted more deer and turkey to the area, year round, than out old corn piles ever did.
