Abstract
In this study pig manure from organic farming systems is composted with passive aeration. Effectiveness of the composting process strongly depended on the density of the compost. Best results were observed at a density of 700 kg/m3, where both aerobic degradation and drying were adequate and temperatures were high enough to kill pathogens and weeds. Monthly turning shortened the process and gave a more homogeneous end product. There were low ammonia and nitrous oxide emissions and no methane emissions.
