Diamond K Premium 97 Solution Grade Gypsum - 50 lbs

Fine, High-Purity Calcium and Sulfur Source - 50 lbs

Coarse gypsum dissolves slowly and leaves you guessing when the calcium and sulfur will actually reach the root zone. This solution-grade gypsum is milled fine and contains 97% calcium sulfate dihydrate, so it goes into solution more readily. Its fineness is documented: 97% passes a 200 mesh screen and 92% passes a 325 mesh screen.

The 50 lb bag suits growers who amend beds, containers or field blocks on a regular schedule and want a manageable unit to handle. Larger operations can order in volume, with a 30-unit order minimum.

Frequently Asked Questions

Q: What is calcium sulfate dihydrate?
A: It is the chemical name for gypsum, a mineral made of calcium, sulfur and water. It supplies calcium and sulfur to plants and soil. This product contains 97% of it.

Q: Why does fineness matter?
A: Finer particles have more surface area, so they dissolve faster. Here 97% of the material passes a 200 mesh screen and 92% passes a 325 mesh screen.

Q: Is the 30-unit minimum a pack size?
A: No. The product is sold as a single 50 lb bag. Thirty is only the minimum number of units per order.

Q: Can it help with sodium-affected soil?
A: Gypsum supplies calcium that helps displace sodium so it can leach away, provided drainage is adequate. Test your soil first to set a suitable rate.

Q: How does gypsum differ from lime?
A: Gypsum adds calcium and sulfur without significantly raising pH, while lime raises pH. Choose based on your soil test.

Q: Where can I find safety information?
A: Review the safety data sheet published by the manufacturer before handling. Avoid breathing the dust and wear appropriate protection when pouring.
