What is the best way to reduce methane emissions when storing manure?
How manure is stored can affect the amount of greenhouse gases it emits. Methane and nitrous oxide emissions are smaller for compost than for slurry or stockpile. In terms of dairy manure, slurry emits 1.9 times more greenhouse gases than compost; stockpiled manure emits 1.5 times more. For beef manure, emissions of methane and nitrous oxide are much lower than in dairy. Slurry emitted 4-6 times more gases than compost, while stockpiling was 1.3 times higher than compost.
