Special Issue Information

Dear Colleagues,

Soil health has long been crucial for sustainable agriculture, with soil degradation and pollution posing major challenges over time. The history of soil amendment and pollution remediation dates back centuries, with early practices focusing on improving soil fertility. However, recent years have seen increased urgency due to industrial pollution, over-fertilization, and climate change-induced degradation, requiring innovative solutions.

This Special Issue aims to explore the role of soil amendment and pollution remediation in enhancing soil quality for sustainable agriculture, providing the related ecosystem services. It covers a wide range of topics, including the development of new amendment technologies, strategies for detoxifying polluted soils, and innovative methods to improve soil structure, biology, and fertility. This issue seeks to examine how these solutions can contribute to long-term agricultural productivity while minimizing environmental harm and enhance soil health.

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. Agriculture is an international peer-reviewed open access semimonthly journal published by MDPI.

Soil degradation is closely related to the core issue of food security, making the assessment and monitoring of paddy soil quality particularly important. To clarify the impact of a rice–red claw crayfish co-culture on paddy soil quality, this research established two experimental groups: a rice monoculture and a rice–red claw crayfish co-culture. Using 16S rRNA and 18S rRNA sequencing technologies, we systematically compared soil characteristics, microbial diversity, and community composition under the two modes. Principal component analysis based on a minimum data set was employed to integrate soil property parameters with bacterial and eukaryotic microbial community indicators for a comprehensive assessment of the paddy soil quality index. The results showed that the rice–red claw crayfish co-culture substantially increased soil total nitrogen, available nitrogen, total phosphorus, available potassium, and cation exchange capacity. Simultaneously, the rice–red claw crayfish co-culture significantly influenced the beta diversity and composition of bacterial and eukaryotic microbial communities, significantly increasing the relative abundances of Bacteroidota, Cyanobacteria, Verrucomicrobiota, Arthropoda, Cryptomycota, and Nematoda. The soil quality index under the rice–red claw crayfish co-culture was markedly higher than that under the rice monoculture. In summary, a rice–red claw crayfish co-culture can enhance soil fertility and improve overall soil quality. By incorporating microbial community parameters into the evaluation index system, this study confirms that the rice–red claw crayfish co-culture system is indeed a sustainable agricultural practice, providing a theoretical basis for refining the soil quality assessment framework for rice–aquatic animal-integrated farming systems.
