Earth Science Fast Acting Gypsum Granules is a 5 lb granular soil conditioner that quickly loosens compacted soils, supplies calcium, helps repair salt-damaged soil, and supports healthier root development with Nutri-Bond runoff reduction technology.
If your lawn or garden struggles with hard, compacted clay or salt-affected patches, a targeted gypsum treatment can improve soil structure without changing pH. These pelletized granules are designed to begin working on contact with soil, easing compaction so water, air, and nutrients reach roots more readily. The included Nutri-Bond technology helps bind nutrients in the soil to reduce runoff and waste so more of what you apply benefits plants.
Earth Science Fast Acting Gypsum is finely ground and pelletized so it starts breaking up compacted clays and dense soils immediately after application. Visible improvements in water penetration and soil workability often appear within days, while cumulative benefits build over several weeks.
Gypsum supplies calcium, a nutrient that can support fruit and vegetable development and help alleviate some symptoms linked to calcium deficiency and salt stress in soil. It does not cure plant diseases, but by improving soil structure and adding calcium, it creates conditions that support healthier root function and reduced salt concentration near roots.
Nutri-Bond is a soil-bonding ingredient blended with the gypsum granules to help nutrients adhere to soil particles so fewer nutrients wash away with irrigation or rain. By keeping more nutrient available near roots, you can expect better uptake and less waste from fertilizer applications.
Earth Science Fast Acting Gypsum is formulated to be safe for use on all turf types and is safe for people and pets to be on the lawn immediately after application. Application is simple: broadcast granules with any standard spreader, then water lightly to activate and move the granules into the soil.
Who this is for: Home gardeners, lawn care DIYers, and small-scale landscapers who need a practical, fast-acting solution to loosen compacted clay soils, repair salt-damaged patches, and add calcium to the root zone. It’s especially useful for vegetable gardeners dealing with blossom-end rot, homeowners battling poorly draining lawns, and anyone wanting to maximize fertilizer efficiency with Nutri-Bond technology. Use as a targeted soil conditioner in lawns, raised beds, container mixes, and ornamental beds where better root access to water and nutrients is needed.
Q: How much gypsum should I apply per 1000 sq ft?
A: Typical rates vary by soil condition; a common starting rate is 10–20 lb per 1,000 sq ft. Check soil needs and adjust accordingly.
Q: Will this change my soil pH?
A: No, gypsum adds calcium without raising soil pH, making it suitable where pH must remain stable.
