Special Issue Information
Dear Colleagues,
Biochar is a solid material, rich in carbon, obtained by thermochemical processes from various organic residues. Biochar as a soil amendment has been widely studied and the results indicate that it can partially or fully replace chemical fertilizers in agricultural production. However, in some cases, low concentrations or imbalanced nutrients may limit the use of biochar as a fertilizer. In view of this, several strategies have been assessed to make use of biochar as a fertilizer viable. Enriching biochar with one or multiple nutrients is a promising strategy to increase nutrient-use efficiency, reduce final product costs and reduce the environmental damage caused by chemical fertilizers, such as nutrient leaching and greenhouse gas emissions. There are several techniques to enrich biochar with nutrients to produce biochar-based fertilizers, including pre- and post-pyrolysis procedures. The feedstocks used to enrich biochar can be grouped into i) chemical fertilizers; ii) organic wastes; iii) rock dust; iv) minerals; and pure inorganic compounds.
This Special Issue welcomes submissions on biochar-based fertilizers including feedstocks, production, and effects on the soil–plant system.
We look forward to receiving your contributions.

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.
