  5. Reducing greenhouse gas (GHG) emissions from agriculture is an important way to mitigate climate change. Diet manipulation influences enteric fermentation and has the potential to reduce GHG emissions; however, few studies have examined the effect of diet composition on GHG emissions after manure is applied to the soil. We conducted a 70-day lab incubation experiment to investigate this knowledge gap and analyze how different manure types affect soil biogeochemical cycling and GHG emissions. We are analyzing the results now and a poster will be prepared and presented at the 21. 21st World Congress of Soil Science in August 2018.
