P. Boeckx ; O. Van Cleemput ; I. Villaralvo | 1996Methane emission from a small covered landfill site showed, seasonally varying fluxes, ranging from -5.9 to 914.3 mg CH4 m(-2) d(-1). The moisture content of the CH4-oxidising cover soil was thought to cause this variation. Comparing gross and n[...]![]()

R. Lessard ; P. Rochette ; E. Topp ; E Pattey ; AL Et | 1994Des enceintes fermées (dix par site) ont été utilisées pour mesurer les dégagements de CH4 et CO2 à la surface de sols agricole (maïs) et forestier (feuillus) adjacents. L'ojectif était de décrire la variation temporelle et spatiale des échanges[...]![]()

K. Goulding ; T. Willison ; C. Webster ; D. Powlson | 1996Aerobic soils are an important sink for methane (CH4), contributing up to 15% of global CH4 destruction. However, the sink strength is significantly affected by land management, nitrogen (N) fertilizers and acidity. The rates of uptake from the [...]![]()

Methane oxidation in two swedish landfill covers measured with carbon-13 to carbon-12 isotope ratios
G. Borjesson ; J. Chanton ; B. Svensson | 2001The release of methane from landfills to the atmospere and the oxidation of methane in the cover soils were quantified with static chambers and a C-isotope technique on two landfills in Sweden.![]()
