I may be wrong, but it is my understanding that you can plant anything for doves: corn, millet, milo, sunflowers, etc. and then bush hog it, disc it, burn it whatever. As long as you do not remove it from the field and redistribute it later. Adding anything not grown there, be it wheat, sunflowers, corn, rock salt etc. is a different story. I may be wrong, but I don't think so!
