It has been widely assessed that the increase in the world’s population, which is predicted to reach nine billion people by 2050, requires that agriculture maintain and/or enhance its productivity potential to meet the global demand of food. Up to now, this objective has been fulfilled by progressively increasing the input of external fertilizers; however, in the last few decades, fertilizer inputs did not enhanced crop yield proportionally, but posed serious threat for the environment. The overcoming of this issue necessarily requires the improvements in nutrients-use efficiency of crops, which can be achieved by deeply understanding and, afterwards, exploiting the intrinsic biological potential of rhizosphere processes.
The rhizosphere is commonly used to describe the volume of soil influenced by root biological activities and it represents a complex and highly-dynamic environment where a vast number of interactions, between roots, minerals, organic compounds, solutes, gases, and microorganisms, determine the biogeochemical cycling of elements. In spite of its pivotal importance, rhizosphere research faces several challenges, mainly related to i) the study of root activities under field conditions, ii) the correlation of the root activities with the physical-chemical alterations of both rhizosphere soil and microbiome, iii) the understanding of the molecular mechanisms underpinning root exudation and nutrients uptake, and iv) modelling acquired knowledge to develop strategies to manage the rhizosphere, aimed at improving agriculture productivity and sustainability.
On these bases, the main aim of this Special Issue, “Rhizosphere Research in Agriculture”, is to bring together the more up-to-date pieces of knowledge concerning: i) the relationships established between plants, soil, and microorganisms in the rhizosphere, ii) the molecular/biochemical mechanisms underlying the release of root exudates and the acquisition of nutrients, and iii) innovative tools and methods for rhizosphere research.

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. Agriculture 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 1800 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.
