Special Issue Information
Dear Colleagues,
Efficient nitrogen (N) management remains a critical challenge in achieving sustainable agricultural intensification. Nitrogen is a fundamental macronutrient for plant metabolism; however, its overuse and mismanagement across diverse cropping systems contribute to severe environmental issues, including nitrate leaching, eutrophication, soil degradation, and greenhouse gas emissions. This Special Issue aims to advance our understanding of Innovative Nitrogen Management Strategies across aquaponics, hydroponics, soilless culture, and soil-based agriculture, with a particular focus on optimizing nitrogen use efficiency (NUE) and minimizing environmental impact. We welcome contributions that explore nutrient cycling in closed-loop systems, precision fertigation technologies, and integrated nutrient solutions that utilize both organic and inorganic fertilizers. Special emphasis is placed on decoupled aquaponics systems, bioponics, and controlled environment agriculture (CEA), where system-specific innovations allow for real-time monitoring and adaptive nitrogen control. Moreover, studies that assess the role of microbial consortia, biochar, and smart-sensor networks in regulating nitrogen transformation and loss mitigation are of particular interest. This Special Issue encourages multidisciplinary research—from molecular insights into plant-nitrogen interactions to system-level models and policy implications—that collectively contribute to a more environmentally sustainable, resource-efficient, and climate-resilient agricultural future.

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 250 words) can be sent to the Editorial Office for assessment.
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. Nitrogen is an international peer-reviewed open access quarterly 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 1200 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.
