About this Research Topic
The nitrogen cycle is one of the most important biogeochemical cycles on the planet and involves a wide range of nitrogen species and biochemical transformations. As an essential element, nitrogen is critical to crop productivity in agriculture, but many environmental issues, such as production of greenhouse and ozone-depleting gases, are linked to the production of nitrogen fertilizer and its extensive use globally. This Research Topic will review current advances in the understanding of a variety of different transformations in the nitrogen cycle at the molecular, physiological and environmental levels. Applications in biotechnology and the interaction of the nitrogen cycle with other biogeochemical cycles, such as the sulfur, iron and carbon cycles, will also be addressed.
Articles to be published in this Research Topic (Original Research, Commentaries, Opinion, Reviews) should contribute to understanding new challenges on the N-cycle from interdisciplinary approaches, summarizing the recent advances presented at the European Nitrogen Cycle meetings.
