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.

Cal-CM+ Plus

The Sucra-Min® family of products are produced using a special manufacturing process. They are created by incorporating finely ground oxides with specific reducing sugars in a proprietary formulation, in the presence of heat and moisture. This process forms an organic complex with the oxides and causes the sugars to hydrolyze and form a carboxylate, or what is more commonly referred to as a sucrate.

Sucra-Min® Iron Sucrate 50 SGN 125 is an iron sucrate micronutrient produced using a unique process that combines agronomically available iron with reducing sugars under controlled conditions to yield iron carboxylate (sucrate). This proprietary prilling technology produces round uniform granules that are free-flowing and anti-caking. Sucra-Min™ Iron Sucrate 50 provides a soil dispersible source of iron that is biologically available at a relatively high nutrient concentration. Sucra-Min™ Iron Sucrate 50 is available in two particle sizes to accommodate all granular applications.

Cal-CM+ Plus™ Agricultural Grade Limestone are derived from a pure calcitic limestone with no detectable magnesium. Cal-CM+ Plus Limestone is primarily used for neutralizing acidic soils (low pH), thereby improving uptake of essential plant nutrients. Cal-CM+ Plus Limestone is finely ground for more rapid release into the soil. Our Rapid Release Technology process finely grinds the CaCO3 to uniform particle size with 100% passing through 100 Mesh. Available in bulk.
