[EN] Vermicompost is analternative to add value to livestock excreta. Particularly, the Universitat Politècnica de València has experimental farms which produce about 500 t of manure every year, from rabbit and small ...
Chemical composition and gas emissions from two types of pig slurry were evaluated: the liquid fraction of mechanical solid-liquid separated slurry (SS), and raw slurry (RS). The slurry was obtained at the end of a pig ...
[EN] Swine production has increased steadily throughout the last decades in the European Union (EU). In Spain, swine census grew 58% between 1990 and 2009, being second-ranked within the EU-27, after Germany. This situation ...
[EN] Low frequency aeration of slurries may reduce ammonia (NH3) and methane (CH4) emissions without increasing nitrous oxide (N2O) emissions. The aim of this study was to quantify this potential reduction and to establish ...
