“…Additionally, the observed dynamic changes in bacterial diversity were consistent with previous study results, including decreases with increasing cultivation age (Ma et al, 2021). It has been shown that in the rhizosphere microbial community of ginseng, cultivation age has a more positive effect on the bacterial community than on the fungal community (He et al, 2022). The rhizosphere environment may be influenced by increasing planting age, and therefore the complex interactions of rootassociated bacteria are more susceptible to changes in the rhizosphere environment than those of fungi.…”

“…Frontiers in Plant Science 09 frontiersin.org community was observed in older plantations compared to younger plantations (Liu et al, 2018a). Additionally, the extent of influence varied between bacterial and fungal communities (He et al, 2022). Despite a long-term legacy of plant growth that exceeds the age of the plant in shaping the microbiome of the rhizosphere, the impact of the latter was hard to ignore (Manici et al, 2017).…”

Rhizosphere microbial communities profoundly affect plant health, productivity, and responses to environmental stress. Thus, it is of great significance to comprehensively understand the response of root-associated microbes to planting years and the complex interactions between plants and rhizosphere microbes under long-term cultivation. Therefore, four rabbiteye blueberries (Vaccinium ashei Reade) plantations established in 1988, 2004, 2013, and 2017 were selected to obtain the dynamic changes and assembly mechanisms of rhizosphere microbial communities with the increase in planting age. Rhizosphere bacterial and fungal community composition and diversity were determined using a high-throughput sequencing method. The results showed that the diversity and structure of bacterial and fungal communities in the rhizosphere of blueberries differed significantly among planting ages. A total of 926 operational taxonomic units (OTUs) in the bacterial community and 219 OTUs in the fungal community were identified as the core rhizosphere microbiome of blueberry. Linear discriminant analysis effect size (LEfSe) analysis revealed 36 and 56 distinct bacterial and fungal biomarkers, respectively. Topological features of co-occurrence network analysis showed greater complexity and more intense interactions in bacterial communities than in fungal communities. Soil pH is the main driver for shaping bacterial community structure, while available potassium is the main driver for shaping fungal community structure. In addition, the VPA results showed that edaphic factors and blueberry planting age contributed more to fungal community variations than bacterial community. Notably, ericoid mycorrhizal fungi were observed in cultivated blueberry varieties, with a marked increase in relative abundance with planting age, which may positively contribute to nutrient uptake and coping with environmental stress. Taken together, our study provides a basis for manipulating rhizosphere microbial communities to improve the sustainability of agricultural production during long-term cultivation.

“…The second crop (i.e., replanted ginseng) had a higher abundance of Acidobacteria, Solibacteres, and Rhizomicrobium in the soil compared to the first crop soil and non-cultivated soil, which was correlated with decreased soil pH caused by long-term ginseng growth. For farmland cultivation of P. ginseng, cultivation age had a more pronounced effect on soil bacteria than on soil fungi with decreasing pH in older soils related to negative impacts on soil bacteria [56]. While overall abundance was higher in 6-than in 5-year-old cultivated soil, beneficial and neutral microbes decreased over time, while potentially harmful microbes, such as the pathogenic fungi, Cylindrocarpon and Fusarium, increased over time.…”

The rhizosphere of ginseng contains a wide range of microorganisms that can have beneficial or harmful effects on the plant. Root exudates of ginseng, particularly ginsenosides and phenolic acids, appear to select for particular microbial populations through their stimulatory and inhibitory activities, which may account for the similarities between the rhizosphere microbiomes of different cultivated species of Panax. Many practices of cultivation attempt to mimic the natural conditions of ginseng as an understory plant in hilly forested areas. However, these practices are often disruptive to soil, and thus the soil microbiome differs between wild and cultivated ginseng. Changes in the microbiome during cultivation can be harmful as they have been associated with negative changes of the soil physiochemistry as well as the promotion of plant diseases. However, isolation of a number of beneficial microbes from the ginseng rhizosphere indicates that many have the potential to improve ginseng production. The application of high-throughput sequencing to study the rhizosphere microbiome of ginseng grown under a variety of conditions continues to greatly expand our knowledge of the diversity and abundance of those organisms as well as their impacts of cultivation. While there is much more to be learnt, many aspects of the ginseng rhizosphere microbiome have already been revealed.

“…Continuous soil management might alter soil properties, and such change varies across planting years [11,[21][22][23][24][25]. For example, the storage of soil carbon, nitrogen, and phosphorus in tea gardens [11] and ginseng fields [25] increases with an increase in planting years. Under conventional farming practices, the soil structure in Brazilian tobacco (Nicotiana tabacum) fields continuously declines with increasing planting years [21].…”

The effects of long-term monocropping systems combined with climate on soil water aggregate stability (WSA) and soil fertility in the karst region of Southwest China (KRSWC) are unclear. Our research was conducted in the KRSWC, wherein tobacco (Nicotiana tabacum) production is characterized by heavy fertilization and continuous monocropping. The tobacco fields in the study area have similar soil types and fertilization and tillage practices and are spread over an area of 11,500 km2. A total of 568 topsoil samples were collected in 2021. Soil fertility was reflected using the soil fertility index (SFI), which was calculated using the minimum data set method with six soil fertility-related factors, namely, soil pH, soil organic matter, cation exchange capacity, available nitrogen, available phosphorus, and available potassium. Results showed that long-term planting generally promoted soil fertility levels and WSA content. WSA and SFI had inconsistent spatial distribution patterns likely due to different climate-driven effects. WSA variability was greatly controlled by precipitation (Spearman correlation coefficient [r] = −0.49, p < 0.01), whereas SFI variability was mostly dominated by temperature (r = −0.36, p < 0.01). The levels of SFI and WSA were optimal under conditions of low temperature and precipitation and poor under conditions of high temperature and precipitation. Moreover, long-term planting could alleviate the negative effects of climate on SFI and WSA in the KRSWC. The results of this study could provide valuable information on fertilization and climate-adapted strategies for tobacco fields in the KRSWC.
