Deterioration of Norway spruce vitality despite a sharp decline in acid deposition: a long-term integrated perspective
Since the late 1970s, several long-term ecological studies were conducted to better understand the biogeochemical functioning of Norway spruce stands in the Ardennes as these nutrient-poor ecosystems were subject to high levels of acid deposition and exhibited symptoms of tree health decline. Between 1978 and 2009, acid deposition declined sharply,...

Evaluation de la pertinence des deux méthodes d'analyse du phosphore dans les sols forestiers.
Deux méthodes d'analyse du phosphore biodisponible des sols sont comparées sur des sols non calcaires : la méthode Duchaufour (deux extraits successifs, le premier à l'acide sulfurique dilué, le second à la soude) et la méthode "Dyer" (extraction à l'acide citrique dilué) et sont mises en rapport avec les résultats d'analyses foliaires. Les deux mé...
Water supply and sulfate pollution of groundwater under agricultural and forested areas. Sub-project 2: Hydrochemical st...
A significant increase in sulphate concentration in groundwater and raw water has been observed in many waterworks in alluvial aquifers in Germany. Quantifying sulphate inputs into groundwater and release from soils is necessary for a sulphur balance and a prognosis of future sulphate concentrations in groundwater. Aims of the project included the ...
