AB - BACKGROUND:Composting is the most frequently used waste management process for animal manure in Korea’s livestock industry. In the composting process, a large amount of nitrogen (N) is volatilized to the atmosphere as amonia (NH3). However, quantitative information of NH3 emission from composting of liquid manure is required to obtain emission factors for management of livestock manure in Korea.METHODS AND RESULTS:To evaluate the NH3 emission from composting of liquid manure affected by aeration, we conducted composting of liquid pig manure with three forced aeration systems. The aeration conditions were continuous (A60), cycle of 30 min aeration and 30 min pause (A30S30) and without aeration(A0). All treatments were aerated 12 hour per day with these aeration systems. The total ratio of NH3 volatilization loss to total N content in liquid manure throughout composting period was estimated to 19.9% for A0 treatment, 25.9% for A30S30 treatment and 36.3% for A60 treatment. The A30S30 and A60 aeration systems increased NH3 volatilization by 30.2 and 82.3% compared with systems without forced aeration.CONCLUSION(S):Ammonia emission during liquid pig manure composting was highly affected by forced aeration. The development of liquid pig manure composting systems with forced aeration would be considered both reducing ammonia emission and efficiency of composting.
