Abstract
Human agricultural activities affect soil quality, which plays an important role in terms of crop quality and food security. Studies of the impact of human agricultural activities on the soil microbiome and soil quality are extremely important, but such studies on floodplains in river valleys are lacking. The aim of this study was to compare the composition of the bacterial community in river muds (Fluvisols) used for blackcurrant cultivation and those not used for agricultural purposes. The study material consisted of three river muds (Fluvisols) collected in Opatkowice in the Lubelskie voivodeship. The area is the natural floodplain of the river and the classification was made on the basis of an agricultural map. Soil was taken from under the blackcurrant crop (C) and from the nearest meadow (M). The composition of the bacterial community in the soil samples was determined using next-generation sequencing (NGS) of the 16S rRNA gene. The results showed that the biodiversity indices obtained from NGS were higher in the soils under blackcurrant cultivation compared to meadow soils. Both variants (C and M) were dominated by Proteobacteria, Acidobacteria and Actinobacteria, but the differences between the abundances of these bacteria in both variants were statistically significant. Analysis of bacterial diversity at the genus level showed that Mycobacterium predominated among the identified taxa, although their distribution of occurrence differed between soils. The results suggest that microorganisms are more abundant and taxonomically diverse in cultivated soils. This suggests that a smaller pool of microorganisms is sufficient to perform all functions in the soil ecosystem in fertile soils unaffected by agrotechnical measures, whereas the maintenance of eubiosis in mechanically and fertilized agricultural soils requires the involvement of more microorganisms with a broader functional spectrum. However, the results presented here are preliminary and these conclusions require further research. 
The research was carried out within the framework of project No. 2019/35/N/NZ9/00830 entitled “The search for bacteria adapting to extreme soil moisture conditions and the assessment of the effects of hydric stress on the quality of the soil environment” funded by the National Science Centre Poland (NCN).
