Arcosa Cal-CM Plus Mini Prilled Gypsum Calcium Sulfate - 1.25 mm Particles

Cal‑CM+ Plus Mini Prilled Gypsum Calcium Sulfate – SGN 125

Cal‑CM+ Plus Mini Prilled Gypsum is a premium soil amendment designed for high‑precision agricultural and turf applications where rapid calcium delivery and soil structure improvement are priorities. Manufactured with Arcosa Specialty Materials’ proprietary Rapid Release Technology, this product combines finely milled calcium sulfate dihydrate and anhydrite into uniform, low‑dust prills that disperse quickly when exposed to moisture.

The mini particle size (SGN 125) is ideal for situations where even coverage and fast dissolution are required, such as topdressing turf, fertigating through surface application, or treating high‑value specialty crops. Each prill breaks down completely to supply soluble calcium and sulfur, two essential nutrients for root development, cell wall strength, and chlorophyll formation. This immediate nutrient availability makes Cal‑CM+ Plus Mini an effective solution for correcting calcium deficiencies and mitigating sodium and magnesium accumulation in soils.

In addition to nutrient delivery, Cal‑CM+ Plus Mini enhances soil aggregation and water infiltration. By replacing exchangeable sodium with calcium, it reduces soil crusting and compaction, improving root penetration and aeration. The product’s highly consistent granule size allows for uniform application through all standard broadcast and drop spreaders without segregation or bridging, making it compatible with most blended fertilizer programs.

Cal‑CM+ Plus Mini Prilled Gypsum is OMRI‑listed for organic production in Washington State and can be applied at a range of rates depending on crop need, soil test results, and irrigation water quality. Whether used as part of a regular fertility program or as a corrective amendment for sodic or compacted soils, it offers a reliable, agronomically proven way to maintain soil health and maximize yields.
