The Art Wilson Co. provides quality soil amendments and fertilizers, including Cal-CM Plus™ Calcium Sulfate and Cal-CM Plus™ Limestone featuring Rapid Release Technology.

Art Wilson Co.’s Cal-CM Plus™ products are superior to competitive products in the market for several reasons, including:

• Our anhydrite-based products are guaranteed 100% Calcium Sulfate, making them superior to all standard gypsum products. The value and efficacy of Cal-CM Plus™ Calcium Sulfate, as well as ordinary agricultural gypsum, is directly related to its percentage of Calcium Sulfate.
• All prilled products, including Cal-CM Plus™ Limestone, have been ground to an extremely fine consistency prior to prilling. Our unique Rapid Release Technology facilitates quick, uniform release of the available nutrients to the soil and plant.
• All Cal-CM Plus™ products are listed with OMRI (the Organic Materials Review Institute), and are suitable for use in certified organic production.
