BuildASoil Montmorillonite (Calcium Bentonite) 4 lb.

Directions: 1/4 cup per cubic foot of potting soil or top dress each plant with 1/4 cup

4 lbs yields roughly 8.5 cups

Montmorillonite is used as a soil additive to increase the CEC of the soil and dramatically enhance the soil profile through natural micronutrients. Calcium Bentonite can hold 1-5 times its weight in water and is used in gardening as it is more stable. Calcium Bentonite stores and releases water much easier than other types of clays. Bentonite clay has hundreds to thousands of times more surface area than sand particles hence it improves nutrient holding capacity of soils and helps provide a better home for soil microorganisms.

- improves the wettability of soils - improves soils water holding ability - increases the CEC (cation exchange capacity) of soils - prevents leaching of many nutrients - makes nutrients from fertilizers or other sources more available to plants - supplies small amounts of calcium, magnesium and potassium - improves soil structure of sandy soils
