well, there are alot of variables with food plots. i tryed a small plot of clover and it was never visited, next year ground it up with the rototiller and let it go wild and i have all kinds of activity now. if its a wooded area try burning it off with a controlled burn. if you cant burn it brush hog it then rototill it. mother nature usally will let somthing grow back. you could dump a ton of money into a food plot and never see anything in it.
