Livestock manure management accounts for almost 10% of greenhouse gas emissions from agriculture globally, and contributes an equal proportion to the US methane emission inventory. Current emissions inventories use emissions factors determined from small-scale laboratory experiments that have not been compared to field-scale measurements. Anaerobic lagoons were the largest source of methane, more than three times that from enteric fermentation. Corrals and solid manure piles were large sources of nitrous oxide. Nitrous oxide emissions from anaerobic lagoons and barns were unexpectedly large. Modeled methane emissions underestimated field-measurement means for most manure management practices. Modeled nitrous oxide emissions underestimated field-measurement means for anaerobic lagoons and manure piles, but overestimated emissions from slurry storage. Revised emissions factors nearly doubled slurry CH4 emissions for Europe and increased N2O emissions from solid piles and lagoons in the US by an order of magnitude. Our results suggest that current greenhouse gas emission factors generally underestimate emissions from dairy manure and highlight liquid manure systems as promising target areas for greenhouse gas mitigation.
