What I've found and seems to work well in rotation...
Fall plot with 50lbs wheat, 5lbs brassicas, 5lbs annual clover (I prefer Balansa as well). IF you get a good stand with little weed competition (won't happen this spring for me due to the severe drought), bushhog in early May and drill 10lbs dwarf sorgham/milo, 10lbs pearl millet, and 20lbs cheap Hutchinson forage beans for summer. If fall plot didn't establish, have to kill the competing grasses and broadleaf weeds chemically before planting summer crop.
The sorgham and millet provides the biomass and root system to improve soil, and is cheap. The beans will grow and vine up the sorgham stalks and provide a legume to nitrify the soil and feed deer.
After summer, bushhog the plot, then terminate with gly, then replant with wheat, clover, brassica. (One year I tried to just drill through the summer plot with the winter blend and the sorgham/ millet was too thick to allow fall plot to establish).
You can add buckwheat, iron clay peas, sunn hemp, sunflowers, etc to the summer blend, but cost of seed goes up exponentially. The blend of only sorgham, millet, and Hutchinson beans can be planted for less than $40 per acre seed cost.
To really crank out the summer biomass, you probably need to add at least 50lbs triple 13 per acre. The millet and sorgham need a lot of nitrogen.... not as much as corn, but close. But all that goes back into the dirt for future fall plots.
