Isotope pool dilution studies are increasingly reported in the soils and ecology literature as a
means of measuring gross rates of nitrogen (N) mineralization, nitrification, and inorganic N …

Average nitrogen (N) deposition across Europe has declined since the 1990s. This resulted
in decreased N inputs to forest ecosystems especially in Central and Western Europe where …

Soil gross nitrification (GN) is a critical process in the global nitrogen (N) cycle that results in
the formation of nitrate through microbial oxidation of ammonium or organic N, and can both …

Soil enzymes, as indicators of microbial metabolism, play an important role in nutrient
biogeochemistry at the ecosystem level. In this study, we present information from a …

The knowledge of tree species effects on soil C and N pools is scarce, particularly for
European deciduous tree species. We studied forest floor and mineral soil carbon and …

A laboratory experiment was designed to challenge the idea that the C/N ratio of forest soils
may control gross N immobilization, mineralization, and nitrification rates. Soils were …

The C: N ratio is considered as an indicator of nitrate leaching in response to high
atmospheric nitrogen (N) deposition. However, the C: N ratio is influenced by a multitude of …

Humans have altered global nitrogen cycling such that more atmospheric N2 is being
converted ('fixed') into biologically reactive forms by anthropogenic activities than by all …

Concern is resurfacing in the United States over the long-term effects of excess nitrogen (N)
deposition and mobility in the environment. We present here a new synthesis of existing …

Application of manure is reported to effectively improve agricultural soil fertility. However, the
potential of annual manure applications to increase stocks of soil organic carbon (SOC) and …
