“…Similarly, pH and AK content were among the main factors associated with bacterial community differences in continuously cropped potato fields ( Zhao et al, 2020 ). Even though pH and nutrient contents affect fungal communities as well ( Glassman et al, 2017 ; Li et al, 2022a ), we found no clear associations between fungal community composition and soil properties.…”

AimsIn garlic cultivation, long-time monoculture has resulted in continuous-cropping obstacles. However, the cause has not been studied to date.MethodsWe analyzed soils from garlic fields in Pengzhou, China, to determine continuous-cropping obstacle related changes in soil physicochemical properties and enzyme activities, and in the diversity and composition of bacterial and fungal communities. Furthermore, we examined the relationships between soil properties and the bacterial and fungal communities.ResultsThe soil pH and the soil catalase, urease, invertase, and polyphenol oxidase activities were lower in the cropping obstacle soil than in the healthy control soil. The richness and diversity of the bacteria were lower in the cropping obstacle soil than in the control. The bacterial and fungal communities in the cropping obstacle soil were clearly different from those in the control soil. The differences in bacterial communities between the cropping obstacle soil and the control soil were associated with differences in pH and available potassium content. The taxa with higher relative abundances in the cropping obstacle soils included potential plant pathogens and the taxa with lower relative abundances included potential plant growth promoters.ConclusionThe enrichment of plant pathogens and the depletion of plant growth promoting fungi may have contributed to the poor growth of garlic in the cropping obstacle soil. The enzyme activity and microbial community differences were associated with acidification that was likely an important factor in the deterioration of the soil ecological environment and the garlic cropping obstacle. The results provide information to guide agricultural practices in cultivating garlic.

“…We also observed that some microbial biofertilizers significantly reduced fungal soil-borne pathogens, even when the cucumber plants were uprooted. That may have been due the presence of beneficial microorganisms in the biofertilizers that had multiplied rapidly and inhibited the growth of pathogens 43 . We observed that 267, BS and HZ were better at controlling soil-borne pathogens than other biofertilizers, but the efficacy of most of them tested reduced during the late growth stage of cucumber.…”

Reductions in the quality and yield of crops continuously produced in the same location for many years due to annual increases in soil-borne pathogens. Environmentally-friendly methods are needed to produce vegetables sustainably and cost effectively under protective cover. We investigated the impact of biofertilizers on cucumber growth and yield, and changes to populations of soil microorganisms in response to biofertilizer treatments applied to substrate or soil. We observed that some biofertilizers significantly increased cucumber growth and decreased soil-borne pathogens in soil and substrate. Rhizosphere microbial communities in soil and substrate responded differently to different biofertilizers, which also led to significant differences in microbial diversity and taxonomic structure at different times in the growing season. Biofertilizers increase the prospects of re-using substrate for continuously producing high-quality crops cost-effectively from the same soil each year while at the same time controlling soil-borne disease.

“…Thirty-six Brassica chinensis L. plants were randomly selected from each treatment plot, and the height, crown width and leaf width of the plants were measured with a tape measure ( Liu et al., 2014 ; Amoah et al., 2017 ). A handheld, non-destructive SPAD chlorophyll meter (SPAD-502, Konica Minolta, Japan) was used to measure the chlorophyll concentration in the plant leaves ( Li et al., 2022c ). The leaves of each plant were numbered from the bottom to the top of the stem ( Alemayehu et al., 2020 ).…”

“…Sequencing was performed on an Illumina Miseq platform (Majorbio Bio-Pharm Technology Co., Ltd., Shanghai, China). Sequences were comparedagainst the Silva (SSU123) 16S rRNA Database and the fungal (ITS) Unite Database to obtain the species annotation information ( Li et al., 2022c ). Sequence data associated with this project have been deposited in the NCBI Short Read Archive database (Accession Numbers: PRJNA862974 and PRJNA863750).…”

As a functional probiotic, Bacillus subtilis can promote crop growth and improve nutrient utilization by various mechanisms, so it has been made into bioorganic fertilizer as a replacement for chemical fertilizer. However, the effects of B. subtilis bioorganic fertilizer application on the yield and quality of commercial crops of Brassica chinensis L., the soil physicochemical properties and the microflora have not been clarified. In this study, pot experiments were conducted using Brassica chinensis L. plants with four fertilization treatments: control without fertilization (CK), chemical fertilizer (CF), organic fertilizer (OF), and bioorganic fertilizer containing B. subtilis (BF). After 30 days of pot experiment, the results showed that BF efficiently improved plant height and biomass (1.20- and 1.93-fold, respectively); as well as significantly increasing soil available potassium and pH value. Using high-throughput sequencing, we examined the bacterial and fungal communities in the soil, and found that their diversity was remarkablely reduced in the BF treatment compared to CK group. A principal coordinate analysis also showed a clear separation of bacterial and fungal communities in the BF and CK groups. After application of B. subtilis bioorganic fertilizer, some beneficial bacteria (such as Bacillus and Ammoniphilus) and fungi (Trichoderma and Mortierella) were enriched. A network analysis indicated that bacteria were the dominant soil microbes and the presence of B. subtilis stimulated the colonization of beneficial microbial communities. In addition, predictive functional profiling demonstrated that the application of bioorganic fertilizer enhanced the function of mineral element metabolism and absorption and increased the relative abundance of saprotrophs. Overall, the application of bioorganic fertilizer effectively changed the soil microflora, improved the soil available potassium and pH value, and boosted the yield of Brassica chinensis L. This work has valuable implications for promoting the safe planting of facility vegetables and the sustainable development of green agriculture.
