I'm another fellow Missouri guy. My land is in Crawford County. Like you I'm a newbie too. I had very good luck with a first attempt on about an acres worth of shaded trails this year using a mix of 50 lbs of Rye, 50 lbs of Oats, 5 lbs Ground hog radish, 6 lbs of medium red clover and 4 lbs of ladino white clover. I sprayed, mowed, resprayed, and then Labor Day weekend I disced, spread cereal grains, cultipacked, spread radishes and clovers and cultipacked again. All with an ATV and walk behind brush mower
With only one years experience I can say the oats, Rye and clover did very well in spite of me and I think they were for me the best choice. Simple is good. The radishes did okay but with no real soil amendments and too much shade they were limited.
This year I've already done soil tests and am awaiting those results. I know I need more light too.
My advice would be keep it simple, don't over complicate things by biting off more than you can chew, but also be as thorough as your limitations allow. And Have fun with it while you learn!
