Black Gypsum DG

Black Gypsum DG granules 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.


  • Contains calcium sulfate dihydrate (CaSO₄ • 2H₂O)
    • Water soluble
    • Increases calcium and sulfur without changing soil pH
  • Humic acid from oxidized lignite (leonardite)
  • 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
