Special Issue Information
Dear Colleagues,
Nitrogen (N) is essential for plant growth, and N fertilizer greatly contributes to world food production. However, excessive or inefficient fertilizer use has led to low N utilization, low efficiency, and increased environmental pollution. Biochar has emerged as a promising soil amendment for regulating N cycling and mitigating N losses in agricultural systems. Nevertheless, the effects of biochar on soil N transformation are highly context-dependent, varying with factors such as soil type, cropping systems, and tillage practices due to the complexity of environmental interactions.
Therefore, we initiated a Special Issue in Agronomy entitled 'Mechanisms and Effects of Biochar in Regulating the Soil Nitrogen Cycle'. This research topic aims to advance our understanding of biochar-mediated N cycling processes and will focus on the following:
- Investigating how biochar alters soil nitrogen processes and elucidating the underlying mechanisms. Submissions addressing experimental and monitoring methods to quantify these processes, including microbial drivers, are also welcome.
- Exploring strategies to enhance soil nitrogen fertility and fertilizer nitrogen use efficiency through biochar application.
- Assessing the long-term agroecological impacts of biochar, including benefits for nutrient retention and greenhouse gas mitigation, to better understand its contribution to sustainable agriculture.
This Special Issue invites high-quality contributions, including original research articles, reviews, and short communications. We particularly encourage field-based studies to bridge the gap between scientific discovery and practical agricultural applications.

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. Agronomy is an international peer-reviewed open access monthly 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.
