The present study aimed to trace the change in microbial communities and the degree of cabbage formation under different variations of the growth medium. Five variants were studied: control - soil, V1 - 10% compost and 90% soil, V2 - 25% compost and 75% soil, V3 - 50% compost and 50% soil, V4 -100% compost. Samples were taken on 15, 30 and 60 days. The amount of total microflora in all variants slightly decreased over time, but the mineralization rate remained almost the same. Throughout the experiment, the main share in the composition of the total microflora was occupied by non-spore-forming bacteria and bacillus, and actinomycetes and micromycetes were less represented. The total amount of microorganisms was higher in the variants with compost compared to the control, highest in the variant with 100% compost content.
