Special Issue Information

Dear Colleagues,

Conservation agriculture (CA) is a powerful tool to improve soil health and promote sustainable agricultural practices. Field and watershed studies have shown that CA increases organic matter content, improves soil biodiversity, reduces erosion, improves water infiltration and storage, and reduces nutrient leaching. By implementing CA principles, farmers can increase crop productivity, protect the environment, and ensure the security of food and nutrition. However, these benefits may be impacted by increasing droughts and climate instability and are site-dependent. It is critical to improve how such concerns are handled to maintain CA's widespread regenerative capabilities while also improving soil resilience and health, enhancing resource efficiency, and facilitating agricultural sustainability for future generations. In this regard, identifying areas for improvement is crucial. This is achieved by investing in research and the development of new technologies and processes that can further increase the benefits of CA. Adapting CA to new environments will also ensure its continued widespread acceptance.

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 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 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.

Organic agriculture is widely regarded as an important approach to reducing biodiversity loss and promoting sustainable agricultural development compared to conventional agriculture. Notably, organic farming practices have substantially boosted the diversity of soil microbial communities. However, empirical studies on the functional structure of soil microbial communities in organic agroecosystems and the mechanisms influencing them remain relatively scarce. Using high-throughput sequencing technology, we analyzed soil microbial communities associated with organic (orange lands) and conventional (coffee and maize lands) farming practices in the Gaoligong Mountains (GLGM) region, with the aim of revealing differences in soil properties, microbial community structure, and functional composition across different agricultural management practices. The results revealed that organic farming boosted soil organic carbon and fertility, driving changes in the microbial community composition. Organic farming notably increased the abundance of bacterial functional groups involved in the carbon and nitrogen cycles but decreased the abundance of symbiotic fungi. Furthermore, no significant differences were observed in the abundance of saprotrophic and pathogenic fungi between the organic and conventional farming systems. The present study demonstrates that organic farming enhances the functional roles of oil microorganisms in nutrient cycling and overall ecosystem processes by enhancing soil’s organic carbon content and soil fertility, thereby modifying the soil’s microbial community structure and functions. Overall, organic farming contributes to improvements in soil health and supports the sustainable development of agriculture in the GLGM region. Full article
