Biochar-Nitrogen Interactions: Mechanisms, Transformations, and Agricultural Impacts

Dear Colleagues,

Nitrogen (N) management plays a central role in agriculture. Recently, the study of N interaction with biochar has gained attention, with this interaction being proposed to maximize N use efficiency in agricultural systems. Nitrogen-rich materials, when pyrolyzed, depending on the pyrolysis temperature, can be sources of N for plants. Additionally, when biochars are mixed at different stages with N sources, this interaction can also improve the N use efficiency for plants. However, for proper management, the mechanisms involved, both during and after pyrolysis, need to be elucidated, creating a foundation for recommendations and guidelines on biochar–nitrogen interaction. This interaction significantly affects N dynamics in plants, as well as its uptake by plants. In this context, this Special Issue aims to promote the advancement of this field and provide more information related to the following:
(i) The dynamics of N during the production of biochars by pyrolysis;
(ii) The interaction between biochar and nitrogen when mixed after pyrolysis;
(iii) Providing information on how biochar–nitrogen interaction affects N dynamics and other elements in the soil;
(iv) Elucidating how these interactions affect nitrogen uptake dynamics in plants.

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. 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 1000 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.
