Special Issue Information
Dear Colleagues,
Agricultural soil is an important source of anthropogenic greenhouse gas (GHG) emissions, and reducing farmland greenhouse gases and enhancing soil carbon sequestration are essential means of mitigating climate change. In recent decades, the overuse of chemical fertilizers has led to a significant increase in the GHG emissions produced by farmland. Fertilizer management practices are commonly suggested as techniques able to enhance the efficiency of fertilizer use and mitigate GHG emissions. Relevant practices include, but are not limited to, the following: The replacement of inorganic fertilizers with organic fertilizers or composted manure partially, thus improving soil quality and increasing crop yield while reducing the quantity of nitrogen fertilizer utilized. The application of nitrification inhibitors in order to significantly increase the efficiency of nitrogen use and reduce the emission of greenhouse gases such as N2O. The development of biofertilizers that enrich and optimize the structure of the soil microbial community, increase the content of soluble nutrients in soil, and improve soil fertility and crop yield. The application of straw-returning and no-tillage measures can increase the content of organic carbon in the soil content and improve soil productivity. In addition, the fertilization method, fertilization time, water and fertilizer integration, etc., all have an important impact on farmland GHG emissions.
In this Special Issue, we aim to collect studies conducted by researchers from all over the world in order to exchange knowledge on farmland GHG emissions under different fertilizer management practices.

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.
