Black Gypsum DG®

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

DG technology from The Andersons 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. The DG technology allows for reduced application rates, as compared to other agricultural-grade gypsum products, which makes this a very economical soil amendment.

Product Features and Benefits 

  • Water soluble formula that contains 70% calcium sulfate dihydrate (CaSO₄·2H₂O)
  • Increases available calcium and sulfur without changing soil pH
  • Contains 10% humic acid, which supplies 15-30 lbs of humic acid per acre
  • Improves root development, plant nutrient uptake and phosphorus stability
  • Enhances soil health by stimulating soil microbial populations and relieving compaction and salinity
  • Blends with fertilizer or can be used alone

Frequently Asked Questions

Q:  What advantages do Black Gypsum DG granules have over other types of standard gypsum?

A:  Our gypsum source is calcium sulfate dihydrate (CaSO₄·2H₂O), which, with two extra water molecules, is more water soluble than the anhydrite form (CaSO₄). These extra molecules make calcium and sulfur more readily available to the plant – as soon as Black Gypsum DG enters the soil solution. While a plant receiving the anhydrite form of calcium would be forced to wait days or weeks to take advantage of the applied nutrients, a plant receiving a Black Gypsum DG application begins to utilize the nutrients in hours, thanks to the dihydrate calcium and our dispersing granule technology. Black Gypsum DG delivers 10% humic acid in every application. This humate is quick acting and provides further chelation of applied and existing nutrients, increasing their availability to the plant.

Q:  How does the application of carbon enhance soil health?

A:  Humic substances contain carbon, which will provide soil microbes with a food source and habitat, allowing them to flourish. As a result, essential macro and micronutrients held in the soil will become more available, and additional fertility will be utilized more efficiently. Humic acids also have a high cation exchange capacity, which enhances the soil’s ability to hold nutrients.

Recommended Broadcast Application Rates

Apply any time as a soil amendment. Consult your soil test results for pH, cation exchange capacity (CEC), organic matter, and soil active carbon levels and apply accordingly.
