Plant-Soil-Microbe Interactions for Sustainable Agriculture and Reforestation

Dear Colleagues,

In recent decades, synthetic chemicals have been increasingly used in agriculture to maximize crop yields. This strategy has led to agrochemical poisoning of the soil, with negative impacts on the planet’s health. The soil system is a nonrenewable resource and, therefore, the development of sustainable alternatives are urgently needed to avoid further worsening of this imbalance and to preserve this delicate system responsible for survival of the planet and its inhabitants.

Several microbial formulations can be utilized in sustainable agriculture to reduce or avoid the use of agrochemicals whilst safeguarding soil biodiversity and planet health. Microbes associated with plants provide advantages to their hosts by promoting their growth and development. The mechanisms by which they perform this positive action can be direct (e.g., nitrogen fixation, abiotic stress tolerance, nutrient solubilization) or indirect (e.g., antagonistic molecule production).

This Special Issue is focused on the different aspects of plant–microbe interactions and on their impact on productive landscapes. We welcome research articles, reviews, communications, and concept papers that address any aspect of plant–microbe interactions—from isolation and formulation of microbial biostimulants and biocontrol agents to utilization effects on plant hosts and soil biodiversity.

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 250 words) can be sent to the Editorial Office for assessment.

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. Sustainability is an international peer-reviewed open access semimonthly 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 2400 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.
