That food source is gone. Do the deer that were coming to that field bed on the property that you can hunt, if so, find the trails that they will be shifting to on thier way to a new food source. If they don' t bed on the property that you can hunt, is there any reason to beleive that they may cross the property while moving from bed to food? Is there any mast crops, acorns, on the property or water source on the property? Take some time and figure out what they are doing differently and adjust your game plan accordingly. If they all left because the food source is gone, it' s time to ask permission on another property.
