Late-rotation soybeans, standing corn, brassicas, and clover plots become high-traffic food sources during mast failures. Stand placement on the food source itself — an evening sit on the upwind edge with quiet entry — produces does and following bucks throughout the rut and into late season.
A partial mast failure (one species failed, another produced) is even more useful because it concentrates deer on the productive species. Walk the woods early October to identify which trees produced and which didn't. Pair with state mast reports.
