The "fast acting" claim proves accurate - within weeks of application, I could see visible differences in water penetration and soil workability.The finely ground pelletized format strikes an excellent balance between effectiveness and ease of application. Unlike powdered gypsum that creates dust clouds or coarse products that take forever to break down, these pellets spread evenly through standard fertilizer spreaders while dissolving quickly when watered.Clay loosening performance is genuinely impressive. Areas where water previously pooled on the surface now absorb irrigation effectively. The soil that once required a pickaxe to dig has become workable with standard garden tools. Root development in newly planted areas appears significantly improved compared to untreated sections.The Nutri-Bond technology seems to work as advertised for reducing nutrient runoff. My established plants show better color and vigor, likely due to improved nutrient retention in the root zone. The calcium addition has noticeably helped my tomatoes with blossom-end rot issues that plagued previous seasons.Safety for immediate use is a major advantage over many soil amendments. Being able to apply and have kids and pets back on the lawn immediately eliminates the inconvenience factor that often delays soil improvement projects.Application through standard spreaders works smoothly without clogging or uneven distribution. The pellets maintain their integrity during spreading but break down appropriately when watered, providing good control over application rates.Results become apparent relatively quickly for a soil amendment, though patience is still required. Initial improvements in water penetration are visible within a few weeks, while structural soil changes continue developing over several months.The product works effectively across different grass types without causing damage or discoloration, making it suitable for mixed landscaping areas.Cost per treated area is reasonable considering the long-term soil improvement benefits, though treating large areas requires significant product quantities.Bottom Line: Effective soil conditioner that delivers measurable improvements in clay soil workability and plant health. The combination of fast action and easy application makes this a practical solution for problematic soil conditions. ### ⭐⭐⭐⭐⭐ Great results from damaged lawn due to road salt *by on Reviewed in the United States July 10, 2026* Because of winter parking restrictions I have to sometimes park my car on my lawn. The corrosive salt the city places on the roads is very damaging to the lawn as it melts off the car. Applied this product to the damaged area then after a couple days of steady rain I added a thin layer of topsoil and added grass seed. I wish I had taken a before and after because the results are amazing. Just reordered because the grandkids were here and someone thought it was a great idea to add liquid dish soap to the slip and slide to make it faster and killed the grass. So this is my second purchase to rehab another section of lawn. ### ⭐⭐⭐⭐⭐ Outstanding Gypsum Product *by on Reviewed in the United States April 1, 2026* Excellent way to apply gypsum to the lawn. Pellets are small and disolve quickly.I have tried applying gypsum previously using big, heavy bags from a local big box store. While much cheaper, practically useless. Concrete chips would disolve quicker. 🙀I had my main sewer line replaced last year and the trench after being filled in was a wide swath of exposed rock hard clay. Reseeding was not working. Began applying this "miracle in a bag" gypsum and I finally could get grass to grow.Highly recommend this gypsum for anyone needing to address clay soil issues. ## Frequently Bought Together - Earth Science Fast Acting Gypsum - Soil Conditioner Adds Calcium, Repairs Salt Damage & Root Growth with Nutri-Bond Runoff Reduction Technology (5 lb) - Earth Science Fast Acting Lime - (5lb) Instantly Raise pH of Soil & Reduce Nutrient Runoff for Improved Growth & Color - Long Lasting Lawn Care with Calcium - Earth Science Fast Acting Sulfur - Instantly Lower pH of Soil & Reduce Nutrient Runoff for Improved Growth & Color - Long Lasting Lawn Care for Acid Loving Plants (5lb) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/530243908-earth-science-fast-acting-gypsum-granules-5-lb-soil-conditioner](https://www.desertcart.at/products/530243908-earth-science-fast-acting-gypsum-granules-5-lb-soil-conditioner) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-25*
