The increasing economic activity reinforces the importance of climate change on a global scale. Together with the development of the economy and the increase in people's well-being, the emissions of greenhouse gases (GHG) which are released into the atmosphere as a result of human activities, also increase. Nitrous oxide (N2O) is one of the main greenhouse and ozone (O3) depleting gases. Seven percent of the anthropogenic greenhouse effect is nitrous oxide. From a molecular perspective, N2O has a 310-fold greater ...

Nitrous oxide (N2O) is one of important greenhouse gas (GHG) whose main sources are agricultural soils. N2O forms in soil as a result of microbial processes, reinforced by the use of nitrogen-containing fertilizers. This study will look at how the formation of N2O in soil is affected by soil moisture and soil granulometric composition. Soil N2O isotopes of ?15N? (central nitrogen position) and ?15N? (end nitrogen position) which could help to identify natural and anthropogenic sources of N2O emissions and the invo...

Agricultural activity accounts for two-thirds of the total anthropogenic nitrogen oxide (N2O) emissions worldwide. Most of the N2O emissions from agricultural soils come from the use of inorganic fertilizers and/or manure. As agricultural activity intensifies worldwide, N2O emissions are currently increasing by 0.25% per year. In order to investigate the feedback of soil N2O emissions with changes in environmental conditions, an improved understanding based on the wider use of isotopic tracer methods is needed. Th...
