### Structure of the Rhizosphere Bacteriobime  
The examination of microbiota diversity conducted at the phylum level revealed that Proteobacteria constituted the most abundant phylum of microorganisms (averaging 43.0%), with the highest prevalence observed in the ZM-w variant (68.6%) and the lowest frequency following the control (31.9%). The second most prevalent phylum was Firmicutes, making up about 19.1% on average. They were most abundant in the TM treatment (27.0%) and least abundant in the ZM-w one (13.5%). Planctomycetota, the third most dominant phylum, with an average of 9.1%, showed the highest frequency in the TM variant (12.7%) and the lowest in the ZM-d variant (4.8%). The frequency of subsequent phyla, i.e., Bacteroidetes and Acidobacteria, fluctuated over 7.0%.  
Detailed analysis (Table 1) revealed a large taxonomic rearrangement compared with the control. On average, the most abundant OTU was the genus _Bacillus_, which was predominant in each variant. Another OTU, the order Rhizoles, was equdominant only in the case of the ZM-w variant, and dominated the microbiome, with more than half of the percentage share. In the remaining variants, this OTU was almost absent. In the case of the order Burkholderiales, a significant increase in the share of this OTU was observed from the occasional class in the control to the equdominant class in the VC and ZM-w variants. OTUs Gemmataceae and Xanthobacteraceae decreased their shares under the influences of the ZM-d and ZM-w treatments. The Comamonadaceae, Rhizolesae, and _Flavitalae_ OTUs reached the equdominant classes, and significant increases in these OTUs, compared with the control, were observed in the ZM-d treatment. The genus _Paneibacillus_ was an occasional OTU under almost every variant, but after the application of TM, it reached the equdominant class. Eudominant taxa in the control, such as Nitrosomonadaceae, _Geoalkalibacter_, and _Terromonas_, significantly reduced their shares, or at least their dominance classes, after the application of any of the tested fertilizers. Other important OTUs, such as Acicmicrobia, occurred only in the VC variant, _Novierbaspirillum_ in TM, Gemmatimonadaceae in the ZM-d treatment, and Piellulaceae in the ZM-w treatment.  
Based on the diversity results, it was observed that, in terms of [PERSON]'s dominance, the TM variant, in which dominance decreased, and the ZM-w variant, which achieved an almost-twice higher dominance index, differed significantly from the control. The Shannon diversity and Pielou evenness indices were significantly higher in the TM and ZM-d variants, and lower in the ZM-w variants (Table 1).  
Based on the results of the hierarchical analysis and nMDS (Figure 1), it was observed that only the VC treatment had a largely similar bacteriobiome structure compared to the control. In contrast, the bacteriobiome structures of the other treatments were much more different from the bacteriobiome in the control. The TM and ZM-d variants were approximately half similar to each other (0.01), whereas the formation of a unique rhizobium, different from those in the other treatments, was observed in the ZM-w treatment.
