Intensive farm systems handle large volume of livestock wastes, resulting in adverse environmental effects, such asudgaseous losses into the atmosphere in form of ammonia (NH3) and greenhouse gases (GHG), i.e. methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O). In this study, the manure management continuum of slurry storage with impermeable cover and following cattle slurry band spreading and incorporation to soil was assessed for NH3udand GHG emissions. The experiment was conducted in an outdoor covered storage (flexible bag system) (study I),udwhich collected the slurry produced in 7 dairy cattle farms (2,000 m3 slurry) during 12 days in the northern Spain.
