Try this method for your new plot it has worked very well for me in the poor soils of reclaimed strip mine of the northern plateau.
First, get rid of the existing foliage by spraying. Wait two or three weeks and till the plot thoroughly. Lime and fertilizer can be tilled in at this time. Follow the soil test reccomendations. If you cannot do a test, then add about a ton or a ton and a half of lime and about 200-250 lbs of 19-19-19 to the acre.
Deer will eat almost anything you plant to some extent but on new plots with poorer soils I have found that a blend of winter grain rye and crimson/white clover and essex rape are hard to beat. The rye is an excellent soil builder and will really help your plot when you plow it under the following year. After a couple of seasons of this mixture switch from rye to oats. Keep the rape and clovers in the mix however.
The deer in my area eat the fall/winter plot down to nearly bare earth by spring. By late winter (early March) you can frost seed the plot with a mixture of red/ladino clovers and some chicory for the spring/summer. This will extend the use of the plot. The clover blend will mature at different times and fix nitrogen into your soil as well which will help with the fall plantings in the future. As the clovers dry out in mid-summer the chicory will be there to keep deer coming! By late summer (September) you will be ready to plow under all this green manure and in a few seasons you will have vibrant and healthy plots that are available as close to year round as you can get with a single plot. The only down time your plot will have will be when you disc it in September. It will take 2-4 weeks for the fall planting to come up enough for deer to use them!
