Main Features

USG Ben Franklin™ No. 1 Agricultural Gypsum is an exceptional source of calcium and sulfur for crop production. It provides a wide range of particle sizes which helps to ensure consistent nutrition throughout the growing season. Applied by a broadcast spreader, Ben Franklin™ No. 1 Agricultural Gypsum:
  • Is more readily available than ag lime which will enable the crop and soil to easily absorb calcium, and can minimize yield-reducing problems
  • Offers superior flow and consistent spreadability
  • Does not significantly affect soil pH – a critical consideration for crop growth
  • Improves the soil structure
  • Is OMRI Listed® - it may be used in certified organic production or food processing and handling according to the USDA National Organic Program Rule
  • Is available at USG facilities in Plaster City, CA and Southard, OK.
