### Chemical Properties of Soils  
As part of the analysis of the impact of various fertilization methods on soil chemical parameters, a detailed examination of soil chemical components was performed after 60 days of beet cultivation. The results show significant differences in the concentrations of key soil components (Table 2, Figure 2). \begin{table}

* OTU abundance results marked with an asterisk indicate a significant difference (\(p<0.05\)), as calculated by [PERSON]’s exact test, compared to the control; it test was used for diversity indices. The background colors in the table represent: green for eudomination (>10.0%), light green for domination (5.1–10.0%), pale green for subdomination (21–5.0%), and white for rare or occasional occurrences (<2%).

Table 1: The structure and diversity of bacteriobiomes depending on the fertilizer used *. Soils fertilized with vermicompost (VC) and dry superworm frass (ZM-d) had the highest concentrations of most of the tested components. In turn, the lowest values of most chemical parameters were recorded in the control soils, except for the P content, which was the lowest in the soil with the addition of mealworm frass, TM. The total nitrogen content (Ntotal) indicates higher concentrations for fertilization with dry superworm frass (ZM-d). In the case of ammonium nitrogen (NH\({}_{4}\)-N) and nitrate nitrogen (NO\({}_{3}\)-N), the highest values were also observed for fertilization with ZM-d, at 336.38 and 1341.80 mg/kg, respectively, significantly higher compared with the control, where the concentration of these ingredients were 203.58 and 949.01 mg/kg. Similarly, the highest concentrations of potassium (K) and calcium (Ca) were also observed in VC-fertilized soils, at 4525 mg/kg and 6275 mg/kg, respectively. Magnesium (Mg) shows less variation between the fertilization methods used, but the ranges on the graph show some variability. The soil fertilized with ZM-w had the lowest Mg content among the tested soils, and the soil without fertilization had the highest. In this study, soil pH changed depending on the fertilizer used.
