I've been lucky enough to take a few deer with a bow on the ground (crp field).A few things I would suggest is to find the trails the deer are coming in on,make sure the wind is right and you are scent free as possible.when I'm hunting a field I will get back in the taller stuff about 10-15 yds and make a few narrow shooting lanes.When hunting in the woods on the ground I like to find the highest spot I can overlooking a trail or creek bottom.around here I have a lot of bluffs and ridges to sit on.
