“…Meanwhile, Streptomyces has the ability to degrade autotoxic substances and has been found to successfully control Fusarium oxysporum and Botrytis cinerea -caused soilborne diseases ( 36 ). Additionally, the type and amount of the organic materials have a greater effect on the generation of anaerobic conditions and the production of volatile organic compounds toxic to plant pathogens ( 18 , 37 ). For example, RSD incorporated with maize straw can effectively inhibit Artemisia selengensis root rot pathogens and the inhibition efficiency can reach 90% when the application rate is 2% ( 38 ).…”

Reductive soil disinfestation (RSD) is an effective method to inhibit soilborne pathogens. However, it remains unclear how RSD combined with different types of organic materials affects the soil ecosystems of perennial plants. Pot experiments were conducted to investigate the effects of RSD incorporated with perilla (PF), alfalfa (MS), ethanol, and acetic acid on soil properties, enzyme activities, microbial communities and functions, and seedling growth. Results showed that RSD-related treatments improved soil properties and enzyme activities, changed microbial community composition and structure, enhanced microbial interactions and functions, and facilitated seedling growth. Compared with CK, RSD-related treatments increased soil pH, available nitrogen, and available potassium contents, sucrase and catalase activities, and decreased soil electric conductivity values. Meanwhile, RSD-related treatment also significantly reduced the relative abundance of Fusarium while increasing the relative abundance of Arthrobacter , Terrabacter , and Gemmatimonas . The reduction was more evident in PF and MS treatment, suggesting the potential for RSD combined with solid agricultural wastes to suppress pathogens. Furthermore, the microbial network of RSD-related treatment was more complex and interconnected, and the functions related to carbon, nitrogen, sulfur, and hydrogen cycling were significantly increased, while the functions of bacterial and fungal plant pathogens were decreased. Importantly, RSD-related treatments also significantly promoted seed germination and seedling growth. In summary, RSD combined with solid agricultural wastes is better than liquid easily degradable compounds by regulating the composition and function of microbial communities to improve soil quality and promote plant growth. IMPORTANCE Reductive soil disinfestation (RSD) is an effective agricultural practice. We found that RSD combined with solid agricultural wastes is better than that of liquid easily degradable compounds, may improve soil quality and microbial community structure, inhibit the proliferation of pathogenic bacteria, and contribute to the growth of replanted crops. Thus, RSD combined with solid agricultural wastes is more effective than liquid easily degradable compounds.

“…Different types of organic materials can have different effects on RSD practices ( 18 ). Currently, organic materials are mainly divided into two categories: liquid and easily degradable materials (like molasses and ethanol) and solid agricultural wastes (like crop straw and livestock manure) ( 19 , 20 ).…”

“…Specifically, our previous study has demonstrated that the relative abundance of Paenibacillus sp. in the RSD incorporated with liquid-readily decomposable compounds (such as molasses) was significantly higher than that amended with solid plant residues (such as sawdust) ( Yan et al., 2022 ). In the present study, therefore, the diseased soil of Momordica charantia severely infected with Fusarium oxysporum f. sp.…”

“…The treatment was followed for 18 days at an average greenhouse temperature of 28~40 °C (randomly measured by a thermometer). The additive amount of molasses and incubation period and temperature during RSD treatment were according to our previous study ( Yan et al, 2022 ), which has demonstrated that RSD treatment under the above conditions can significantly improve soil quality by improving soil microbial community and function. The plastic films in the RSD treatments were then removed, and the soils were then drained.…”

Reductive soil disinfestation (RSD) is an anaerobic and facultative anaerobic microbial-mediated soil management process. The extent of improvement of diseased soil properties by RSD relative to comparable healthy soil is, however, not well characterized. Importantly, how to promote the colonization efficiency of these facultative anaerobic functional species to ensure soil and plant health remain unknown. Here, Fusarium wilt-diseased soil of Momordica charantia grown under a plastic-shed field (PS-CK) was used to conduct molasses-RSD (MO-RSD) along with Paenibacillus sp. (a model of facultative anaerobic species) (MOPA-RSD) treatment, and the soil from a nearby open-air paddy field was considered comparable healthy soil (OA-CK). Both RSD treatments significantly improved the properties of PS-CK soil, and the extent of improvement of soil pH, Fusarium oxysporum reduction efficiency (98.36%~99.56%), and microbial community and functional composition were higher than that achieved for OA-CK soil, which indicated that RSD-regulated most soil properties outperformed those of the comparable healthy soil. The disease incidence and ascorbic acid content of M. charantia in MO-RSD- and MOPA-RSD-treated soils were considerably decreased, while the weight and soluble protein contents were correspondingly increased, as compared to those of M. charantia in PS-CK soil. Specifically, the changes in these physiological properties of M. charantia in MOPA-RSD soil performed well than that in MO-RSD soil. The relative abundances of Cohnella, Effusibacillus, Rummeliibacillus, Oxobacter, Thermicanus, and Penicillium enriched in both RSD-treated soils were positively correlated with Paenibacillus and negatively correlated with F. oxysporum population and disease incidence (P < 0.05). Notably, the relative abundances of these potential probiotics were considerably higher in MOPA-RSD-treated soil than in MO-RSD alone-treated soil. These results show that the RSD process with inoculation of Paenibacillus sp. could promote the colonization of this species and simultaneously stimulate the proliferation of other probiotic consortia to further enhance soil health and plant disease resistance.

Chemical soil fumigation (CSF) and reductive soil disinfestation (RSD) have been proven to be effective agricultural strategies to improve soil quality, restructure microbial communities, and promote plant growth in soil degradation remediation. However, it is still unclear how RSD and CSF ensure soil and plant health by altering fungal communities. Field experiments were conducted to investigate the effects of CSF with chloropicrin, and RSD with animal feces on soil properties, fungal communities and functional composition, and plant physiological characteristics were evaluated. Results showed that RSD and CSF treatment improved soil properties, restructured fungal community composition and structure, enhanced fungal interactions and functions, and facilitated plant growth. There was a significant increase in OM, AN, and AP contents in the soil with both CSF and RSD treatments compared to CK. Meanwhile, compared with CK and CSF, RSD treatment significantly increased biocontrol Chaetomium relative abundance while reducing pathogenic Neonectria relative abundance, indicating that RSD has strong inhibition potential. Furthermore, the microbial network of RSD treatment was more complex and interconnected, and the functions of plant pathogens, and animal pathogen were decreased. Importantly, RSD treatment significantly increased plant SOD, CAT, POD activity, SP, Ca, Zn content, and decreased MDA, ABA, Mg, K, and Fe content. In summary, RSD treatment is more effective than CSF treatment, by stimulating the proliferation of probiotic communities to further enhance soil health and plant disease resistance.
