Technical Abstract: This paper will discuss the USDA-NRCS conservation practice standard regarding the use of gypsum products in agriculture. Gypsum products include gypsum (CaSO4 .2H2O), has been used as an agricultural soil amendment for over 250 years as a soluble source of calcium and sulfur for crops. Research has also demonstrated that gypsum application can improve soil physical and chemical condition as well. The standard addresses the use of gypsum to improve soil physical and chemical properties as it is related to natural resources conservation. Specifically, the standard addresses the use of gypsum to 1) improve soil physical/chemical properties to increase infiltration and reduce soil erosion; 2) reduce dissolved phosphorus concentrations in surface runoff and subsurface drainage; 3) mitigate subsoil aluminum toxicity; and 4) reduce the potential for pathogen transport. These soil improvement can be very important in conjunction with environmental concerns associated with animal waste applications. The specific details of the new conservation standard will be discussed.
