I guess the only exception would be if you are also feeding over the summer. Unless you are useing a weatherproof feeder you cant put out enough feed to last a couple weeks. The last thing you want is to hurt your deer by letting them eat too much or eat feed that gets wet and spoiled. If you are feeding for pictures out by the soybeans,away from their bedding area and not bumping them ,and checking your cameras/feed only midday, you should be fine every few days.When they strip off velvet around the first of september you should not be feeding anymore and only glassing the soybeans from a distance. They will go off their pattern and disappear at that time if pressured at all.
