Special Issue Information
Dear Colleagues,
Nowadays, greenhouse gas (GHG) emissions are an important concern because of their direct effect on global warming and climate change. According to the Intergovernmental Panel on Climate Change (IPCC, 2019), agriculture, forestry, and other land uses contributed to 23% of the total net anthropogenic GHGs emissions during 2007–2016, which represented 13%, 44%, and 81% of the carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), respectively. Agricultural soils are the main source of anthropogenic N2O, which are emitted especially during inefficient nitrogen (N) utilization, over-doses, or non-synchronised mineral fertiliser application to crops. This N excess produces an important imbalance in the soil N cycle, leading to concomitant environmental risks such as an increase in the GHGs fluxes, soil acidification, biological diversity losses, and human health and economy problems. For these reasons, GHG mitigation strategies should be focused in pursuing agricultural practices that could lead to a reduction in the over-application of N fertilizers, without compromising the yield productivity.
We invite the scientific community to contribute TO this Special Issue with research articles and reviews including chemical, biological, or multidisciplinary aspects of the N2O emissions derived from agronomy. Studies based on CO2, CH4, and N2O soil emissions; N cycle processes; fertilizer application; agricultural management practices; microbial diversity; or alternatives to mineral fertilizers are also welcomed.

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.
Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
