3. Limestone Grit: Produced in a fashion similar to limestone flour, limestone grit is rated
according to particle size after being screened through varying meshes. Limestone grit is
an excellent structural additive but has low buffering abilities. A number 9 grit is recommended.
4. Dolomitic Limestone: This limestone is rarely used by Agaricus growers due to its high
magnesium content. Some researchers have reported depressed mycelial growth in cas-

ings high in magnesium.
5. Marl: Dredged from dry lake bottoms, marl is a soft lime similar to chalk but has the consistency of clay. It is a composite of clay and calcium carbonate with good water holding
capacity.

6. Oyster Shell: Comprised of calcium carbonate, ground up oyster shell is similar to limestone grit in its buffering action and ifs structural contribution to the casing layer. But
oyster shell should not be used as the sole buffering agent because of ifs low solubility in
water.

Casing Formulas and Preparation
The following casing formulas are widely used in Agaricus culture. With pH adjustments they
can be used with most mushroom species that require a casing. Measurement of materials is by
volume.
