I just read last weeks Parade magazine with Howard Buffet on the front cover.  It appears that he is standing in a field of forage/tillage radishes!  Picture inside shows him standing if a field with what appears to be worked ground.  Anbody know if he is a cover cropper and/or a no-tiller?  Just curious.
