Special Issue Information

Dear Colleagues,

The pursuit of carbon neutrality in agricultural systems has gained significant momentum in recent years, driven by the urgent need to mitigate climate change and its adverse impacts on global food security. Agriculture has been both a significant contributor to greenhouse gas emissions and a potential solution through carbon sequestration practices. This Special Issue of Agronomy seeks to explore innovative pathways towards achieving carbon neutrality in agricultural systems.

This Special Issue covers a diverse array of topics, including but not limited to novel agricultural practices, advances in soil carbon sequestration, precision farming technologies, bio-based solutions, and multi-objective collaborative management strategies. We aim to highlight cutting-edge theoretical and applied research addressing the complex interplay between agricultural practices, carbon emission, and climate change adaptation and offering actionable insights for farmers, scientists, and policymakers alike.

We invite submissions of original research and review articles that contribute to the understanding of the role of agricultural systems in carbon neutrality and propose new solutions for reducing the sector's carbon footprint. Special consideration will be given to interdisciplinary studies that combine agronomy, soil science, and environmental modeling to offer comprehensive solutions.

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.

Perennial crops are crucial for enhancing soil organic carbon (SOC) stocks to mitigate climate change, yet the effects of planting duration on SOC stocks remain inconsistent. In the agro-pastoral ecotone of northern China, where soil degradation is a growing concern, daylily, a perennial crop cultivated for over 600 years, presents both ecological and agricultural potential. This study evaluates the impact of long-term (LD, >10 years) and short-term (SD, ~5 years) daylily cultivation on SOC stocks and identifies key drivers. Paired soil samples (0–100 cm) from eight sites under LD, SD, and long-term maize cultivation (CK) were analyzed using analysis of variance (ANOVA), correlation analysis, random forest, and structural equation modeling (SEM). LD significantly increased SOC stocks by 19.63% compared to CK, while SD showed no significant difference. The sampling site had a greater impact on SOC stocks than the treatment across different geographic locations. At the same location, SEM revealed that soil factors influenced SOC differently across treatments: for LD, soil total nitrogen (TN) > pH > soil water content (SWC); for SD, TN > SWC > soil available phosphorus (AP); for CK, TN > soil available potassium (AK) > SWC. This study provides insights for regional soil management and carbon sequestration strategies, highlighting the role of LD in enhancing soil quality and promoting ecological restoration. Full article
