Black Gypsum DG - 50lb Bag

Black Gypsum DG granules (SGN 240) are homogenous and combine natural gypsum and humic substances to form a unique bio-amendment.

DG Technology creates a dust-free, spherical, ultra-dry granule that rapidly disperses into thousands of microparticles upon contact with moisture. These microparticles deliver calcium, sulfur, and carbon directly into the soil.

FEATURES AND BENEFITS
- Contains calcium sulfate dihydrate (CaSO₄ • 2H₂O) (17% Ca, 13% S)
- Humic acid (10%) from oxidized lignite (leonardite)
- Water soluble
- Increases calcium and sulfur without changing soil pH
- Improves root development, nutrient uptake, and phosphorus stability
- Provides secondary nutrients (calcium and sulfur)
- Enhances soil health by stimulating soil microbial populations and relieving compaction and salinity
- Blends with fertilizer or can be used alone
