Dynamic model for methane emission from manure storage

摘要: Publisher Summary Methane emission from liquid manure is an important source of greenhouse gases agriculture. Methanogenic bacteria produce methane when decomposes in anaerobic environment. Manure management practice a dominant factor determining emissions. emissions agricultural sources should be calculated accordance with the IPCC good guidelines, based on factors and activity data. Emission are volatile solids content, biodegradability conversion (MCF), which differs per system climate region. Not included models dynamic storage systems, like time, loading unloading rates, temperature. A new model has been developed to include these effect slurry pit accumulation system. Experimental results show that velocity (m3/h) linearly increasing filling time. The relation between time quadratic. used derive values for MCF, depending applied typical dairy pig farm, large figures. proposed can improve calculations national
