Special Issue Information
Dear Colleagues,
The use of organomineral fertilizers (OMFs) has recently increased, and they mainly comprise fertilizers synthesized through processes such as composting, pyrolysis (biochar), and the use of humic substances. Compared with mineral fertilizers, OMFs can enhance crop productivity, especially in soil conditions where nutrients naturally have low use efficiency when applied via soil.
The synthesis route used, as well as the properties and nutrient pools in OMFs, controls the efficiency of the applied nutrients. For some nutrients, reducing the amount of readily soluble nutrients while maintaining available fractions has a high correlation with nutrient crop demand, thus increasing their use efficiency.
In addition to directly controlling nutrient availability, these classes of fertilizers, compared to mineral fertilizers, contain organic compounds that can act as plant biostimulants due to their organic matrix, which mainly comprises organic compounds. However, little is known about this effect in this class of fertilizers, with studies primarily focused on pure organic materials such as biochar, compost, or humic substances.
Therefore, the aim of this Special Issue is to provide more information related to the properties and nutrient pools in OMFs, linking these characteristics to increased nutrient use efficiency, biostimulant effects, and enhanced plant production in order to promote the advancement of this field.

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.
