Special Issue Information

Dear Colleagues,

This Special Issue focuses on the central theme of “Diversified Cropping for Sustainable Soil Fertility and Efficient Crop Production”. It seeks to systematically elucidate the synergistic regulatory mechanisms by which diversified cropping systems—such as intercropping, relay cropping, crop rotation, fallow, and mixed cropping—influence soil physicochemical and biological fertility. Simultaneously, it aims to explore technical approaches and region-specific strategies that effectively balance soil health preservation with high-efficiency crop production. The scope of this issue spans interdisciplinary research areas, including innovative cropping system design, dynamics of soil fertility evolution, mechanisms underlying enhanced crop productivity, integration of supporting agronomic practices, and large-scale regional demonstration projects. Existing studies have predominantly focused on soil fertility or crop production in isolation. This Special Issue is poised to fill the research gap regarding the coupling mechanisms among “diversified cropping–soil fertility sustainability–efficient crop production”, enrich the theoretical system and technical support for sustainable agricultural development, and align with the journal’s core positioning of addressing sustainability challenges and advancing multi-dimensional integrated 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 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.

A systematic elucidation of soil ammonia (NH3) volatilization (SAV) and the underlying drivers is imperative for evaluating NH3 pollution mitigation strategies and advancing sustainable agricultural practices. Currently, no scientific consensus has been established on the effects of maize–soybean intercropping on SAV across varying nitrogen (N) application rates. A consecutive field experiment was conducted over a 2-year period from 2024 to 2025 with a split-plot design. The experiment comprised three cropping systems (maize monocropping (MM), soybean monocropping (MS), and maize–soybean intercropping (IMS)) and three N application rates (no N application (NN), 20% reduced N application (20%RN), and conventional N application (ConN)). The results demonstrated that N application markedly increased SAV. Accumulative SAV was 4.94–6.01 kg ha−1 under NN treatment, whereas it was 8.21–27.89 kg ha−1 under ConN treatment, 7.25–21.52 kg ha−1 under 20%RN treatment. Under ConN treatment, the accumulative SAV in IMS was 21.34 kg·ha−1 and 27.89 kg·ha−1 in 2024 and 2025, respectively, which were significantly higher than those in MM by 16.80% and 13.33%. Under 20% RN treatment, the accumulative SAV in IMS was 15.46 kg·ha−1 and 19.24 kg·ha−1 in 2024 and 2025, respectively, which were lower than those in MM by 3.07% and 10.59%. SAV was positively correlated with soil ammonium N concentration. Moreover, within an appropriate range, SAV increased in response to rising soil water content and temperature. Collectively, maize–soybean intercropping integrated with a 20% nitrogen reduction mitigated environmental risks associated with reactive nitrogen losses. This system constitutes a stable yield, resource-efficient, and ecologically sustainable cropping practice. Full article
