“…It was found that Proteobacteria and Acidobacteriota were the dominant phyla in the soil microbiome in the soils sampled from both fields K20 and K21. Nevertheless, the relative abundance of these bacteria varied with the season and the cropping system, which is consistent with previous studies [60][61][62]. It turned out that a marked increase in the Proteobacteria abundance was recorded in summer, both in K20 and K21, although surprisingly, the highest abundance was also recorded in the rasters of field K21, where the long-term maize monoculture was carried out.…”

The choice of appropriate agricultural practices has a significant impact on soil quality, crop productivity, or soil microbial community. Ten representative soil samples were collected in Wierzchucin Królewski (Kujawsko-Pomorskie Province, NW Poland), an agricultural area belonging to the Potulicka Foundation Group. The cropping systems included a maize monoculture grown continuously for over 30 years and an intercropping mixture (Gorzow mixture) applied in 2020. The study aimed to determine the effect of the intercropping system on the quality and biodiversity of the studied soils and to identify bacterial indicators of sensitivity and resistance to long-term maize monoculture. Therefore, in this study, the impact of the intercrop mixture application on the chemical and biological soil properties and on the diversity of the bacterial community was evaluated by amplifying the 16S rRNA gene sequences and indicators of sensitivity and resistance to long-term maize monoculture were recommended. The results showed that intercropping had a positive effect on soil features and increased the richness and diversity of soil bacteria at the taxonomic level of genera compared to the maize monoculture. Massilia and Haliangium were proposed to be bacterial indicators of sensitivity, while Sphingomonas was recommended to be an indicator of resistance to long-term maize monoculture. Overall, our results evidenced that using an intercropping system may be a sustainable agricultural practice in this area and in north-western Poland.

“…However, the intercropping of Chinese chestnut and tea in separate seasons was complex. Previous studies have demonstrated that seasonal variation regulates soil physiochemical properties and microorganisms (Aon and Colaneri 2001;Onwuka 2016;Li et al 2019;Wu et al 2019;Upton et al 2019;Zhang et al 2020). Spring is the shared growing season for both tea plants and Chinese chestnut trees and results in competition for soil nutrients.…”

This study was to determine the composition and diversity of soil microbial communities and evaluate the effect of intercropping on soil fertility in the tea-Chinese chestnut intercropping system. The Illumina platform was used to characterize the rhizosphere bacteria in the intercropping systems. The rhizospheric soil in intercropping systems in fall was enriched in soil organic matter, available phosphorus, and available potassium, and these were positively correlated with several bacterial taxa including Chloroflexi, WPS-2, Bacteroidota, Myxococcota, Bacteroidota, and Patescibacteria. These bacteria permitted the tea plants to obtain sufficient amounts of nutrients from the soil. In spring, the total nitrogen, total phosphorus, and total potassium of the intercropping system of tea and Chinese chestnut planted in the 1980s (80 T) increased, and these nutrients were positively correlated with Myxococcota, Latescibacterota, Bacteroidota, Deinococcota, Bdellovibrionota, SAR324 Clade (Marine Group B), and Patescibacerlai. In addition, several bacteria (Geobacter, Halomonas, Luteolibacter, Adhaeribacter, and Paludibaculum) contained in the 80 T sample in spring and fall were determined to be beneficial for the soil based on previous studies. The effects of intercropping and monocropping on soils were more complex in spring compared to those with fall, and Chinese chestnut tree age had a strong effect on soil. Our results highlight the need to fully consider factors such as tree age and season in the design of intercropping systems as well as collect additional data for scientific applications of intercropping systems.

“…Numerous studies have shown that seasonal variation strongly regulates soil physiochemical properties and microorganisms [ 10 , 59 , 60 , 61 , 62 ]. However, no studies have assessed the seasonal variation in soil properties and microbial communities in the rhizosphere of C. yuhsienensis .…”

Camellia yuhsienensis Hu, endemic to China, is a predominant oilseed crop, due to its high yield and pathogen resistance. Past studies have focused on the aboveground parts of C. yuhsienensis, whereas the microbial community of the rhizosphere has not been reported yet. This study is the first time to explore the influence of seasonal variation on the microbial community in the rhizosphere of C. yuhsienensis using high-throughput sequencing. The results showed that the dominant bacteria in the rhizosphere of C. yuhsienensis were Chloroflexi, Proteobacteria, Acidobacteria, Actinobacteria, and Planctomycetes, and the dominant fungi were Ascomycota, Basidiomycota, and Mucoromycota. Seasonal variation has significant effects on the abundance of the bacterial and fungal groups in the rhizosphere. A significant increase in bacterial abundance and diversity in the rhizosphere reflected the root activity of C. yuhsienensis in winter. Over the entire year, there were weak correlations between microorganisms and soil physiochemical properties in the rhizosphere. In this study, we found that the bacterial biomarkers in the rhizosphere were chemoorganotrophic Gram-negative bacteria that grow under aerobic conditions, and fungal biomarkers, such as Trichoderma, Mortierella, and Lecanicillium, exhibited protection against pathogens in the rhizosphere. In the rhizosphere of C. yuhsienensis, the dominant functions of the bacteria included nitrogen metabolism, oxidative phosphorylation, glycine, serine and threonine metabolism, glutathione metabolism, and sulfur metabolism. The dominant fungal functional groups were endophytes and ectomycorrhizal fungi of a symbiotroph trophic type. In conclusion, seasonal variation had a remarkable influence on the microbial communities and functions, which were also significantly different in the rhizosphere and non-rhizosphere of C. yuhsienensis. The rhizosphere of C. yuhsienensis provides suitable conditions with good air permeability that allows beneficial bacteria and fungi to dominate the soil microbial community, which can improve the growth and pathogen resistance of C. yuhsienensis.
