Special Issue Information

Dear Colleagues,

This Special Issue aims to advance the understanding of soil microbiology, plant–soil interactions, and biochemical processes that regulate soil functions and ecosystem dynamics. Emphasizing interdisciplinary approaches, it welcomes original manuscripts exploring the role of soil microorganisms in nutrient cycling, soil health, agricultural sustainability, and ecosystem services.

Key topics include the ecology of soil microorganisms, plant–soil relationships, and the interactions between soil microbiome, physical properties, and chemical properties. Studies applying innovative molecular, microscopic, and analytical techniques to soil microbiota dynamics are highly valued. Manuscripts should address mechanistic insights, integrating soil microbiology, plant nutrition, agronomy, mineral fertilizers, organic amendments, and environmental sciences, particularly in human-managed and semi-natural systems.

The journal prioritizes research that bridges fundamental discoveries with practical applications, enhancing sustainability and resilience in agricultural and natural systems while providing novel perspectives on soil ecosystem functions. Interdisciplinary and groundbreaking contributions are especially encouraged.

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.

Zygophyllum coccineum L. and Haloxylon salicornicum are dominant plant species in the natural habitats of Saudi Arabia. The soil microbiome is indispensable for nutrient cycling and stress resilience. In the present study, the analysis of soil nutrients under the two plants displayed variable differences in total N, K, Zn, Mn and Cu, with significant differences in both K and Mn (p ≤ 0.05). In general, the available soil nutrients were higher under Haloxylon than Zygophyllum plants, reflecting higher N, K, Fe and Cu contents in the leaves of the Haloxylon plant. Metagenomic analysis of soil microbiome revealed that the top abundant bacteria at the phylum level were Actinobacteriota, Chloroflexi and Proteobacteria, whereas the uppermost fungal communities were Ascomycota, followed by Basidiomycota. The predicted abundant enzymes in the bacterial communities included Phosphoadenylyl-sulfate reductase, Serine-type D-Ala-carboxypeptidase, ADP-glyceromanno-heptose 6-epimerase and glutathione hydrolase. The fungal communities associated with Haloxylon possessed more than 48 enzymes that differed in their richness from the communities of Zygophyllum. Pentose-P and Sulphate-Cys pathways disclosed the extreme abundant pathways in Zygophyllum bacterial communities, while the nonoxipent pathway was overabundant in the Haloxylon fungal communities. While genomic predictions provide insights into functional potential, integrating these data with environmental parameters remains key to managing soil health. Full article
