The treeline Crushed Mineral Rock Deer Attractant is a self-fed vitamin and mineral supplement for growing and breeding deer. This deer attractant is fortified with key vitamins and organic trace minerals. Sourced from naturally occurring salt mineral deposits, this deer mineral is a great way to attract and nourish deer. Simply pour it down on a 4x4 area and allow several rain cycles to thoroughly soak the mineral. It will soak into the earth, creating a mineral lick. Refresh throughout the year as needed. It can be used in combination with 12 lb. Deer Mineral Rock (sold separately).
