How to Use Mineral/Salt Mixes
By Kent Kammermeyer

Mineral supplements should be placed in February (South) and March (North) to coincide with spring green-up. Any earlier than this will waste salt because it leaches downward through the soil during rain events before deer begin using it. Apply the mineral salt at the rate of about one 50-lb bag per 200 acres for easy access by all deer. Dig a shallow depression on a flat surface of clay soil and mix the salt with the soil. Reapply pure salt and mix with dirt in June. No salt is needed for fall or winter when deer quit using it anyway. Look for bag salt with an analysis of 25-40% Sodium Chloride, 16-18% Calcium and 8-10% Phosphorus. Block salt does not contain enough Calcium and Phosphorus which is essential for antler growth, doe lactation and fawn rearing. According to your soil tests, both are limiting on your propery and may be contributing to your skull fracture problems. Cooper Seed Co. has this high Calcium/Phosphorus salt for a very reasonable price.
