NutraSoft OP Gypsum is an OMRI listed organic, granulated gypsum soil amendment for lawns and gardens. Applying NutraSoft OP Gypsum is will loosen hard-packed and heavy clay soils, allowing for deeper root growth and better water penetration and retention. It is also ideal for soils with high sodium as it removes harmful salts that can prevent seed germination and negatively effect plant growth. A high-quality blend of natural deposits containing calcium and sulfur, NutraSoft OP Gypsum can help repair pet spots and counteract winter salt damage. It can be used any time during the growing season on all turf types without any risk of burning. Made with the Andersons patented DG Technology, NutraSoft OP Gypsum is more effective and faster acting than traditional gypsum products. Each pellet of NutraSoft OP Gypsum is created by grinding nutrients into a fine powder before granulating them with a water-soluble binder. This allows the granules to quickly and completely dissolve into the soil after coming into contact with water from rain or irrigation.

The spreader settings for this product were established using standard equipment available from the spreader manufacturer at swath widths and speeds typically used within the industry. Many variables such as walking speed, terrain, particle size, density, and spreader condition can affect these settings. Spreader settings are intended as a guide and unit calibration should still be performed to ensure proper application rates. They are not intended to replace calibration.
