KC I grew up and huntied Crawford, Phleps, and Maries county moust of my life. The soil in these counties really suck for growing food plots. What we always did was use a winter wheat mixture. Winter wheat will do good in this soil every year and oats do very well. You could also through something like a cow pea with it. I my uncle lives in North Crawford county almost on the Gascanade county line. He uses this mixture and does quite well with it.
Also who ever suggested liming, listen to them no matter what you plant. Find an MFA - not sure what part of Phelps your in or I could tell you where to rent a line buggy. But be prepared to lime at a minimum of once every other year. If it were me, I would get the ground opened up as sson as I could after season.
