Cal-CM+ Plus – Dual Benefits

Works Fast. Lasts Longer.

Cal-CM+ Plus™ is a blend of two forms of Calcium Sulfate: Gypsum Anhydrite and Gypsum Dihydrate providing dual benefits to your soil. This proprietary blend of these two forms of calcium sulfate provide a dual release effect. This means both immediate and long term benefits of adding Ca+ to your soil. Cal-CM+ Plus™ will always have a higher concentration of calcium than simple gypsum products. Arcosa Specialty Materials provides quality soil amendments and fertilizers, including Cal-CM+ Plus Calcium Sulfate and Cal-CM+ Plus Limestone featuring Rapid Release Technology.

Arcosa Specialty Materials’ Cal-CM+ Plus products are superior to competitive products in the market for several reasons.


First, our anhydrite-based products are guaranteed 100% gypsum equivalent analysis (23.28 % Calcium and 18.62 % Sulfur), making them superior to all standard gypsum products. The value and efficacy of the Cal-CM+ Plus, Calcium Sulfate and gypsum blend is directly related to its industry leading percentage of Calcium Sulfate.

Second, 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. Finally, all Cal-CM+ Plus products are listed with OMRI (the Organic Materials Review Institute), and are suitable for use in certified organic production.


Cal-CM+ Plus Calcium Sulfate

Cal-CM+ Plus Calcium Sulfate is pelletized for ease of spreading and dust control.  Ideally suited for use on golf course greens and tees, in general agriculture and gardening, on lawns, and in landscape and ornamental applications.  Ideal for drop spreader application.

Our micronized Solution Grade readily dissolves in water and is usually delivered through an existing irrigation system in turfgrass and agricultural applications. Improves calcium and sulfur deficient soils, and improves water conditions (i.e., excessive sodium), for enhanced turfgrass and plant development.
