Although it is well established that soils are the dominating source for atmospheric nitrous
oxide (N2O), we are still struggling to fully understand the complexity of the underlying …

Background Knowledge of biological and climatic controls in terrestrial nitrogen (N) cycling
within and across ecosystems is central to understanding global patterns of key ecosystem …

The nitrogen (N) cycle involves a set of N compounds transformed by plants and microbes.
Some of these N compounds, such as nitrous oxide (N 2 O) or nitrate (NO 3−), are …

We report a new method for measurement of the isotopic composition of nitrate (NO3-) at the
natural-abundance level in both seawater and freshwater. The method is based on the …

Soils are the main sources of the greenhouse gas nitrous oxide (N2O). The N2O emission at
the soil surface is the result of production and consumption processes. So far, research has …

Denitrification, the reduction of the nitrogen (N) oxides, nitrate (NO3−) and nitrite (NO2−), to
the gases nitric oxide (NO), nitrous oxide (N2O), and dinitrogen (N2), is important to primary …

Nitrous oxide (N 2 O) is one of the key trace gases playing an important role in global
climate change. Soils are the most important source of global N 2 O. A large number of …

Fixed nitrogen limits primary productivity in many parts of the global ocean, and it
consequently plays a role in controlling the carbon dioxide content of the atmosphere. The …

The intramolecular distribution of nitrogen isotopes in N2O is an emerging tool for defining
the relative importance of microbial sources of this greenhouse gas. The application of …

We report the first measurements of coupled nitrogen (N) and oxygen (O) isotope
fractionation of nitrate by laboratory cultures of denitrifying bacteria. Two seawater strains …
