El impacto de la ganadería y la agricultura en los ecosistemas terrestres.-Tratamiento de purines de ganado porcino en España para minimizar la contaminación de suelos y su impacto ambiental

Abstract

ABSTRACT The pig farms in Spain have experimented on the last years a great development, giving place to a new productive, sanitary, economic and environmental reality. His intensification has generated the presence of farms of great capacity, which generate high quantities of excrements and residues. Due to the dynamism of the sector, the legislative existing frame until ends of the nineties of the past 20th century remains obsolete. For such motive, the Government of Spain establishes basic standards of management of pig farms (RD 324/2000); regulatory rules for awarding grants to projects that seek to improve environmental management of pig farms (RD 987/2008); and, in December 2008, is approved, in Ministers' Council, a plan of bio-digestion of excrements, which has as aim decrease the greenhouse gases and reduce the risk of pollution of soils, fluvial riverbeds and undergrounds aquiferous.
