Get soil tests. Cheap or free from you County agent. Correct if needed, ph especially.
Throw bush hog in barn and only bring it out every 3-4 years. Let that grow up in briars , goldenrod, etc ,and successional vegetation creating soft edge.
Create plots in central western 2/3 of plot with minor discing if you want, or spray gly, broadcast clover/ grain mix mid August. Rotate or include in mix the following fall, brassica. You can plant together as I do, or plant separate on a rotational mix each Aug. If that existing crap is fescue, then you probably will need to spray and disc to expect a food plot to take hold. Expect couple years for rotations to improve soil texture and control existing flora.
Hinge cut, or selective timber into 20 yds of forest off field edge to create softer edge from hard forest to field edge. Deer love edge. Repeat deer love edge. No matter how you create it with small or large plant or topography .
Play the wind on access. Don't over hunt. Kill big buck. Ok, the latter is no guarantee. Theres a guy on here that manages hilly, wooded hunting ground. He's a bit off his rocker but knows the delema of managing less than ideal soils. Good luck.
