More than 30 years have passed after the collapse of Soviet Union, and huge areas soil were left in a fallow state. The study microbiological status soils is an extremely urgent task because represent “hidden” food basket Eurasia. In this context, we studied influence land use type (pasture, vegetable garden, hayfield, or secondary afforestation) on key agrochemical parameters microbial biodiversity. All anthropogenically transformed included analysis showed increased humus content pH shift to more neutral side compared mature soil; same seemed be case for all nutrient elements. It was established that factor regulating microbiome composition duration degree irreversibility agrogenic impact. phyla microorganisms Pseudomonadota, Acidobacteriota, Verrucomicrobiota, Bacteroidota, Actinobacteriota. proportion other quite variative different use. At time, 30-year-old abandoned similar each reference 130-year-old monoculture gardens. Thus, first factor, composition, continuation transformation. second if age equal territory one initial podzol landscape. are intermediate terms biodiversity between pristine natural podzols plaggic podzol. could suggested involvement agriculture, may turn under intensive amelioration.
