I'd get the wheat seed,fertilizer,pell lime and alfalfa seed all mixed together put in a fertilizer spreader. Say you want 250#s of total mix per acre spread it at 125#s and go over the field twice then just roll it in that's how I seed down fields and it works great. Our local elevator mixes it all and I spread it.The pell lime helps carry the grass seeds is what I'm told.

I'd seed it this fall but don't over plant the wheat.
