Greenhouse gas and ammonia emissions after slurry spreading and influence of slurry treatment
Abstract
Slurry application to arable land is followed by NH3, N2O and CH4 emissions. Slurry composition is one of the key factors that determine greenhouse gas and ammonia losses. The research project aimes at quantifying NH3, N2O and CH4 emissions after surface application of slurry in dependency on the slurry treatment. The following treatments are included in the investigations: raw slurry without any treatment (fresh and after a six months storage), anaerobically digested slurry (fresh and after a six months storage), slurry after mechanical separation of solids (fresh and after a six months storage), aerated slurry (after a three months storage) and slurry with chopped straw addition (after a three months storage). In August 2000 the trials are carried out with dairy cow slurry, in August 2001 pig slurry will be applied. Ammonia emissions are measured with the large open dynamic chamber developed by ILUET (Institute of Agricultural, Environmental and Energy Engineering). Ammonia concentrations in the incoming and in the exhaust air are continuously analysed by high resolution FTIR spectroscopy. N2O and CH4 emissions are quantified with closed chambers. N2O and CH4 concentrations are analysed by gaschromatography. Slurry composition prior to application, climate, soil water content and soil N content are analysed, as well.
