Ray, Lauren2023-10-052023-10-052023-10https://hdl.handle.net/1813/113571Dairy farms considering or already using anaerobic digestion of their manure have to account for the digestate effluent in their nutrient management planning. Impacts to volume of digester effluent compared to influent, digestate nutrient composition and remaining volatile solids that can convert to methane, are described. The option of using and impermeable cover and flare system on digestate long-term storage reduces precipitation volume and can yield additional carbon credits or value from the digester operation. An estimate of methane produced from digestate storage under varying conditions and a comparison to methane from raw manure storage is included.en-USPRO-DAIRYdairymanuregreenhouse gasnutrientdigesterarticle
