Halving N Waste: Quantification and Abatement of Reactive N Losses to the Atmosphere in Cropping Systems

Dear Colleagues,

The recent XXI International Nitrogen (N) Workshop celebrated in Madrid in October 2022 (https://nworkshop.org/) faced the challenge of halving the waste of N from agro-food systems considering different systems and spatial scales. Losses of this valuable resource have major environmental (e.g., gaseous emissions of reactive N to the atmosphere) and economic impacts. The ambitious goal of halving N waste by 2030 requires the implementation of effective reduction practices to reduce pollution, economic costs, and to develop reliable and accurate emission inventories. In the present Special Issue, we are calling for cutting-edge research to share the current knowledge about measurements of direct or indirect gaseous N losses (N₂O, NH₃, NOx) and quantification of the mitigation potential of management practices to be implemented in cropping systems.

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. Agronomy 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.
