Juarez-Rodriguez et al. applied the sludge derived from anaerobically digested cow manure in the production of biogas (methane-air), to maize (Zea mays L.) cultivated in a nutrient-low, alkaline-saline soil with EC 9.4 dS m 1 and pH of 9.3. The results showed that the C02... 

Environmental pollution is the subject of many political and social discussions in the Netherlands. This is mainly caused by the concentration of the animal husbandry farms close to the villages and cities. There are technical treatments of air and slurry to decrease the odour of it. Anaerobic digestion is one of these. This technology is known from biogasproduction. Most countries in the western world have studied this possibility for renewable energy. A lot of technical problems are solved but on most places it is not possible to produce biogas from farm waste to a competitive price. What is the feasibility for biogas production if there is a need for reduction of the odour emission on the farm ... 

Since more than 10 years much research is done on the anaerobic digestion from slurry. This research is mainly stimulated by the option of the renewable energy biogas. But there is also an effect on the presence of the malodorous compounds. In the next chapter more details are presented. 

Three major system components which need to be examined when assessing the technical feasibility of using anaerobic digestion to produce methane gas from animal manure include i) manure handling ii) biological process stability and iii) biogas handling.
