Special Issue Information
Dear Colleagues,
Nitrogen is the most abundant element on the planet, covering 78% of the atmosphere, with great importance for life as it is an essential component of DNA and proteins or enzymes and a key nutrient of plants participating in the fundamental reaction of plant life i.e. in photosynthesis. Nevertheless, atmospheric nitrogen is not available to most organisms and in order to be used by them, it must be converted to reactive compounds (e.g. the oxidizing forms NO3-NO2- and the reducing forms of NH3 and NH4 +). N of the atmosphere can be bound by natural processes, through lightning, and by biological fixation to terrestrial and aquatic systems. However, the quantities bound by these processes, are not adequate for the demands of the ecosystems, which are supplemented by reactive forms of N that can be produced in unlimited quantities after the discovery of the Haber-Bosch process that allows the conversion of N2 to NH3/NH4 on an industrial scale (Denk et al., 2017). Nitrate is the most important form of soil N for plants, agricultural production, environment, and human health, positively or negatively, entering their body through the food chain (Tsadilas, 2022). The N cycle includes a number of compounds converted by plants and microorganisms. Among these intermediate forms is NO3- which, in addition to their importance for agricultural production, can create serious problems in the environment, endangering biodiversity and climate. Therefore, the processes controlling the conversions of N in the soil are of particular importance as well as monitoring them through the techniques and methods that have been developed up to date. These two main purposes, biogeochemical processes governing N transformations in soils and their monitoring in the soil are the subjects of this special issue.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
