The Andersons Black Gypsum DG 21% Humic Acid Dispersible Granule Fertilizer - 1000 Pound Super Sack (2/Plt)

Black Gypsum DG®: The Ultimate Bio-Amendment for Your Soil

Introducing Black Gypsum DG®, a one-of-a-kind bio-amendment that brings together natural gypsum and humic substances in a homogeneous granule form.

Leveraging the innovative DG technology from The Andersons, Black Gypsum DG® forms dust-free, ultra-dry, spherical granules that disperse rapidly into thousands of microparticles upon contact with moisture. These microparticles deliver calcium, sulfur, and carbon directly to the soil. Thanks to the DG technology, Black Gypsum DG® allows for reduced application rates compared to other agricultural-grade gypsum products, making it a cost-effective soil amendment.

Product Features and Benefits

• Water-soluble formula containing 70% calcium sulfate dihydrate (CaSO4⋅2H2OCaSO4​⋅2H2​O)
• Enhances available calcium and sulfur without altering soil pH
• Contains 10% humic acid, supplying 15-30 lbs of humic acid per acre
• Boosts root development, plant nutrient uptake, and phosphorus stability
• Promotes soil health by stimulating soil microbial populations and alleviating compaction and salinity
• Can be blended with fertilizer or used independently

Frequently Asked Questions

• Q: What advantages does Black Gypsum DG® have over other standard gypsum types?

• A: Our gypsum source is calcium sulfate dihydrate (CaSO4⋅2H2OCaSO4​⋅2H2​O), which is more water-soluble than the anhydrite form (CaSO4CaSO4​) due to two extra water molecules. 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 have to wait days or weeks to utilize the applied nutrients, a plant receiving a Black Gypsum DG® application begins to utilize the nutrients within hours, thanks to the dihydrate calcium and our dispersing granule technology. Black Gypsum DG® delivers 10% humic acid in every application. This quick-acting humate 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 provides a food source and habitat for soil microbes, allowing them to thrive. As a result, essential macro and micronutrients held in the soil become more available, and additional fertility is utilized more efficiently. Humic acids also have a high cation exchange capacity, enhancing the soil’s ability to hold nutrients.

Recommended Broadcast Application Rates

• Row crops, specialty crops, horticulture crops: 150-300 lbs per acre
• Soil detoxification: 600-800 lbs per acre

Apply at 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.
