Earth Science Fast Acting Gypsum—5 lb— Soil Conditioner Adds Calcium, Repairs Salt Damage & Root Growth with Nutri-Bond Runoff Reduction Technology

Soil Amendment That Actually Delivers on Clay Improvement After battling compacted clay soil in my yard for years, this Earth Science gypsum has made noticeable improvements that justify the investment. 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 product

I use it to enhance the soil as it has a lot of clay so I use it annually to allow my grass to get deeper roots. So far so good.

I had my driveway power washed. And although the workers used only a mild chlorine solution, the run off drained onto my plum trees. Suddenly they looked dead and dropped all their leaves. I was upset and in a panic. I googled the situation and was advised to add gypsum and copious amounts of water to the soil to improve aeration. I did. Gratefully the trees have come back. I am most grateful for the instruction and this gypsum.

This gypsum brand has been a lifesaver and clay soil changer! This clay soil has been the bane of our existence and wanted to find something to help with this. Well ..this was it! The soil that was like rock. Now it's actively cracking, becoming soft and now the doggos paws make paw prints!!! Thank you!!!!!
