Special Issue Information
Dear Colleagues,
Grasslands, critical for carbon sequestration and nutrient provisioning, face unprecedented pressure from climate change. Soil microorganisms drive biogeochemical cycles sustaining these ecosystems, yet their regulatory mechanisms remain incompletely understood. Historically, research focused on abiotic factors or plant dynamics; only recently has the integrative role of microbial communities in grassland resilience gained prominence.
This Special Issue aims to synthesize mechanistic insights into how soil microbes mediate carbon and nitrogen fluxes in grasslands under climate change stressors. We seek interdisciplinary studies linking microbial traits, community dynamics, and process rates to predict ecosystem functioning. The scope spans microbial physiology, community ecology, biogeochemistry, and modeling.
We highlight the following:
Microbial feedbacks to warming, nitrogen deposition, drought, and elevated CO₂;
Trait-based approaches linking microbial diversity to C/N turnover;
Plant–microbe–mineral interactions governing soil organic matter persistence;
Multiomics integration (genomics, metabolomics) to uncover regulatory networks;
Microbial management strategies enhancing grassland sustainability.
We invite original research, reviews, and methodological advances addressing the following:
Field/experimental studies quantifying microbial-mediated C/N cycling;
Novel assessments of microbial functional traits and metabolic efficiency;
Cross-scale integration (molecular to ecosystem) of microbial controls;
Predictive modeling of microbial–climate interactions;
Restoration ecology focusing on microbial functional recovery.

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.
