Arcosa Cal-CM Plus Ag Grade Gypsum Calcium Sulfate - 4.75 mm Particles - 48,000 Pound

Cal‑CM+ Plus Ag Grade Gypsum Calcium Sulfate is a high‑purity soil amendment engineered for large‑scale agricultural operations requiring durable, slow‑dissolving prills. This grade is manufactured with Arcosa Specialty Materials’ proprietary Rapid Release Technology, blending calcium sulfate dihydrate and anhydrite into uniform, low‑dust pellets designed for broad‑acre broadcast application.

The 4.75 mm particle size (SGN 475) provides maximum durability and extended nutrient release. Each large, dense prill is formulated to withstand long transport distances, extended storage, and high‑speed mechanical spreading, making it ideal for operations managing hundreds to thousands of acres at a time. Once applied and exposed to moisture, the prills gradually dissolve, supplying a steady release of soluble calcium and sulfur over an extended period.

Cal‑CM+ Plus Ag Grade Gypsum improves soil structure by displacing exchangeable sodium, reducing compaction, and enhancing water infiltration. These physical benefits, coupled with a consistent supply of calcium and sulfur, promote strong root development, improved nutrient uptake, and greater tolerance to environmental stress. The larger particle size makes this grade especially effective in arid or windy environments, where smaller particles may be lost before reaching the target soil profile.

The product is compatible with standard broadcast applicators and can be blended with other coarse‑granular fertilizer products when uniform spreading and controlled breakdown are required. It is suited for use on row crops, forage systems, orchards, and other high‑acreage operations where season‑long calcium and sulfur nutrition is essential.

Whether used as part of a continuous soil‑health program or as a corrective amendment for saline and sodic soils, Cal‑CM+ Plus Ag Grade Gypsum Calcium Sulfate offers reliable performance and agronomic value at scale.
