Here's the page out of the USF&W migratory bird that deals with what is baiting and what is not. Doves and waterfowl are different in the fact you can manipulate
a standing, grown crop for doves and cannot
for waterfowl. The word and meaning of " Manipulate"
does not include flooding a standing agricultural crop for the purpose of hunting migratory waterfowl. It is perfectly legal to flood a standing crop for hunting. It is perfectly legal to flood a harvested crop for hunting as long as the crop was harvested under normal, accepted agricultural processes.
In neither, dove or waterfowl hunting, is it permissible to spread, pile or otherwise place grain, salt or any other attractant on the ground for the purpose of hunting the migratory bird. You can bush hog, burn, push down or otherwise manipulate
a standing crop for doves
If you are in doubt, I would suggest you copy and print the page or pages I have referenced and carry them with you in case you encounter a warden who is not "up" on the regulations. I assure you they are out there. I deal with them weekly.
If you are unsure, still, you may pm me with your idea of what you want to do and I will advise you accordingly.
