| Storage and land application of livestock manure causes considerable odor nuisance to the surrounding neighborhood. Anaerobic digestion and separation of slurry change composition and physical properties of slurry and may therefore lessen the odor pollution during storage and land application. An experiment was set up to study the effects of anaerobic digestion and separation of slurry on the emission of odor. Odor concentration above treated and untreated slurry was compared during storage and following land application using GC/MS analysis and dynamic dilution olfactometry. Slurry concentrations of malodorous volatile fatty acids were reduced by between 79 to 97% by anaerobic digestion, while concentrations of malodorous phenolic and indolic odor... |

| By anaerobic digestion of crops and manure it is possible to produce energy, organic fertilizers and good quality feed with a high content of amino acids. This can be one solution to solve the problems concerning the competition between food and energy crops. At the same time, the production of energy by anaerobic digestion limits the use of fossil fuels. In this study the productive performance of maize and grass silage in terms of biogas and CH4 yield was analysed. The variation of amino acids content of these crops and of cattle and pig manure by anaerobic digestion was studied also. |

| Including grass leys in organic arable rotations has potentially several benefits such as suppression of certain weeds, increased biodiversity (i.e. pollinators), increased soil carbon sequestration and productivity among others. The biomass from the grass mixtures can be refined into protein feed concentrate for monogastrics that can partly replace imported soybean, while the fibre fraction can be used as ruminant feed or for biogas. The grass mixtures can also be used directly for biogas. Increasing diversity of the mixtures will potentially also increase the yield stability and the benefits for biodiversity (pollinators), while the number of cuts per year will also have an effect. Thus, the use of multispecies mixtures in organic arable rotation for... |

| After anaerobic digestion (AD) of manures for biogas production the concentration of ammonium-N is increased and the concentration of decomposable carbon in manure is decreased. That implies that the first year fertilizer value of the manure can be increased by the treatment. However, pH is also increased by AD thereby increasing the risk of ammonia losses while the lowered dry matter content on the other hand improves the manure infiltration in soil and reduces the risk of ammonia loss. Therefore the effects of AD on plant N availability can be expected to interact with the manure application method used. In stockless organic farming it has been suggested that nitrogen utilization can be improved by using anaerobic digestion of plant-based green... |

| Animal manures and plant-based manures are used for biogas production by anaerobic digestion (AD). After AD the concentration of ammonium-N in manure is increased and the concentration of decomposable C is decreased. Thus, the potential first year fertilizer value of the manure can be increased by the treatment. However, pH is also increased by AD thereby increasing the risk of ammonia losses. The objective of this paper was to compare N turnover in soil after application of digested and corresponding undigested manures, and to compare N fertilizer values of digested manures after direct injection or surface-banding in cereals. After AD of pig and cattle slurry the increase in potential plant availability was equivalent to 10-25% of total manure N. AD of... |
