The whole waterfoul (baiting) is a very grey line area, It just depends on the warden! If you look at example Eagle Lakes Outfitters they flood areas of there cornfields I personally would call that baiting. Did not mean to get off the thread topic sorry.
If you don't manipulate the crop or spread it you are good to go. If it is harvested under standard harvest methods it is considered baited for a period of time or until all the crop is removed from the harvested portion. If you flood it, then knock it down it may be considered baited for the season and is technically off limits to hunting for the season.
Grow it, flood it and don't manipulate it and you won't have any issues.
I'm pretty sure you can legally hunt any crop that is harvested/spilled/left in a manner normal to that crop. In fact, on page 34 of the waterfowl regs under What Is Illegal?, fourth paragraph it says you cannot hunt "where grain is present and stored... ...because they have exposed grain
not related to normal agricultural planting, harvest or post-harvest manipulation..." Bold is my emphasis which indicates that if it is there due to normal practices, which would include missed ears or spilled grain at harvest transfer points, it is perfectly legal to hunt and is not considered baited.
