A preview of the useful topics that will be discussed and presented via posters and informational sessions at the Waste to Worth Conference in Seattle, a group of professors and extension professionals present about the use of gypsum in dairy bedding. Gypsum recycled from dry wall is used to supplement traditional bedding materials with agronomic, milk quality, and cow health benefits. But once in the manure storage, gypsum bedding is a source of sulfur that leads to increased hydrogen sulfide gas production. This toxic gas is commonly found at deadly levels in enclosed manure pits, though dangerous levels are found even around outdoor open-air storages during agitation of gypsum manure. An application for continuing education credit for Certified Crop Advisors (CCAs) and members of the American Registry of Professional Animal Scientists (ARPAS) has been submitted.
