“…It can be speculated that this environment is also conducive to N 2 O emissions via nitrifier denitrification if NO 2 2 accumulates because of selective inhibition of NOB (de Boer and Kowalchuk, 2001;Kool et al, 2011). Indeed, Fukumoto (2006) showed that addition of NOB to a compost prevented NO 2 2 accumulation and N 2 O emission.…”

Ongoing intensification and specialisation of livestock production lead to increasing volumes of manure to be managed, which are a source of the greenhouse gases (GHGs) methane (CH 4 ) and nitrous oxide (N 2 O). Net emissions of CH 4 and N 2 O result from a multitude of microbial activities in the manure environment. Their relative importance depends not only on manure composition and local management practices with respect to treatment, storage and field application, but also on ambient climatic conditions. The diversity of livestock production systems, and their associated manure management, is discussed on the basis of four regional cases (Sub-Saharan Africa, Southeast Asia, China and Europe) with increasing levels of intensification and priorities with respect to nutrient management and environmental regulation. GHG mitigation options for production systems based on solid and liquid manure management are then presented, and potentials for positive and negative interactions between pollutants, and between management practices, are discussed. The diversity of manure properties and environmental conditions necessitate a modelling approach for improving estimates of GHG emissions, and for predicting effects of management changes for GHG mitigation, and requirements for such a model are discussed. Finally, we briefly discuss drivers for, and barriers against, introduction of GHG mitigation measures for livestock production. There is no conflict between efforts to improve food and feed production, and efforts to reduce GHG emissions from manure management. Growth in livestock populations are projected to occur mainly in intensive production systems where, for this and other reasons, the largest potentials for GHG mitigation may be found.Keywords: methane, nitrous oxide, storage, treatment, farm model ImplicationsLivestock manure is a source of greenhouse gas (GHG) emissions, mainly as methane and nitrous oxide. GHG emissions are biogenic and regulated by manure characteristics, and therefore emissions can be manipulated via handling, treatment and storage conditions. Globally, livestock production systems vary widely, and this is also true for GHG mitigation potentials, but generally efforts to conserve nutrients in manure for crop production will also reduce GHG emissions. Future growth in livestock production is projected to occur mainly in confined animal feeding operations, which also appear to have the greatest potential for GHG mitigation. IntroductionSince the mid 20th century, there has been a growing pressure on land resources for production of food and feed for livestock and, increasingly, crops for energy production (Hoogwijk et al., 2005). To fulfil the demand for meat, milk and eggs, livestock production in developing countries is expanding, especially in peri-urban areas (Gerber et al., 2005), and worldwide becomes more specialised (Steinfeld et al., 2006). In consequence of these trends, increasing volumes of livestock manure are produced, which are a source of greenhouse gases (GHGs) contributing t...

“…First, there was a difference in the scale of piled manure compared to that of the previous study (Fukumoto et al 2006). In the case of piled compost, the volume of the anaerobic portions established inside the pile may increase logarithmically compared to the volume of aerobic portions as the scale of the compost pile increases.…”

“…At the practical scale employed in the present trials, N2O mitigation reached 11% in Run 1, but conversely increased to 38% in Run 2. In following the procedure previously reported by Fukumoto et al (2006), mature compost was added at the 6-week turning since N2O generation had started in both runs. Figure 3 shows the changes in daily N2O emissions and BOD degradation during composting.…”

“…The population sizes of ammonia-oxidizers and nitrite-oxidizers of the compost materials were determined by using the MPN method. The basal medium and procedures were based on a previous study by Fukumoto (2006). Ten grams of raw sample with 90 ml of sterilized distilled water (DW) were shaken for 20 min., and then the shaken slurry was diluted for a tenfold series.…”

“…In swine manure composting, ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) are involved in the nitrification process. Fukumoto et al (2006) reported success in regulating N2O emissions during composting at laboratory-scale facilities by harmonizing these related bacterial populations. They showed that the nitrogen dioxide (NO2 -) accumulated and N2O emissions generated during manure composting could be controlled by the addition of NOB, and using such as mature compost.…”

We investigated the environmental effects of gas regulation practices using nitrite-oxidizing bacteria (NOB) for nitrification promotion in practical-scale manure composting experiments. With several tons of swine manure piled in parallel chambers, we determined the effects of adding NOB to matured swine manure by conducting two runs of composting trials. Both the control pile (without NOB) and the experimental pile (with NOB) were stored in composting chambers under continuous ventilation, and composting entailed several turnings in following the general swine farming procedure. During all periods of composting, the concentrations of greenhouse gas (GHG) and ammonia (NH3), ventilation rate, and temperature were measured every hour. We found that the addition of NOB significantly increased both the nitrate nitrogen (NO3 --N) and nitrite nitrogen (NO2 --N) content of compost products. However, environmental gas regulations were not met in the two runs. The addition of NOB effectively reduced N2O under oxidation facultative conditions (Run 1), but N2O increased in the passive-type compost under cool temperature conditions (Run 2). N2O emissions were found to largely depend on the manure composting conditions.
