Arcosa Cal-CM Plus Standard Prilled Gypsum Calcium Sulfate - 2.60 mm Particles

Cal‑CM+ Plus Standard Prilled Gypsum Calcium Sulfate – SGN 230

Cal‑CM+ Plus Standard Prilled Gypsum is a high‑quality soil amendment formulated to deliver calcium and sulfur in a reliable, controlled‑release form. Manufactured using Arcosa Specialty Materials’ Rapid Release Technology, this product combines finely milled calcium sulfate dihydrate and anhydrite into durable prills that disperse effectively once in contact with moisture.

The standard particle size (SGN 230) makes this grade well suited for broad‑acre agricultural fields and large‑scale turf applications where slower breakdown and longer‑lasting soil impact are desired. Each prill is engineered for low dust and consistent size, ensuring accurate mechanical spreading and even coverage across wide swaths of ground.

As it dissolves, Cal‑CM+ Plus Standard supplies immediately available calcium and sulfur to support strong root systems, cell wall development, chlorophyll production, and overall plant vigor. It is especially effective in mitigating sodium accumulation in sodic soils, improving soil tilth and water infiltration by replacing sodium with calcium on soil exchange sites. These improvements help alleviate crusting and compaction while increasing water and air movement in the root zone.

The larger SGN prills provide slower dissolution compared to the mini grade, making this product ideal for growers who want extended nutrient availability and reduced handling loss in windy or arid conditions. It can be blended into dry fertilizer programs or applied directly using broadcast spreaders.

Cal‑CM+ Plus Standard Prilled Gypsum is widely used on row crops, forage, permanent plantings, and turf systems to enhance soil chemistry and support high‑yield production systems. It is OMRI‑listed in Washington State for organic production and performs consistently across a broad range of soils and climates.
