“…Thus, for technogenically disturbed areas, the microbial composition serves as an indicator of the degree of soil recovery and indicates the nature of internal processes, being one of the most sensitive ecological indicators of different stages of pedogenesis. In combination with agrochemical predictors, the composition of microorganisms can serve as a criterion for assessing the suitability of restored soils for a particular type of economic activity [22,29,30].…”

This research evaluates the development of microbiomes in primary soils, forming in various mining dumps in the arid terrain in the Republic of Bashkortostan, Russia. A metagenomic analysis of the communities was performed by sequencing extended gene sequences. The evaluation of the agro-chemical properties was in accordance with conventional pedology methods. Inverse voltammetry was used to measure the heavy metals (lead, cadmium, mercury, zinc, copper, and nickel) and arsenic content. In all the samples studied, Actinobacteria and Proteobacteria phylas dominated, and, in smaller numbers, Acidobacteria and Bacteroidetes were present. In the natural samples, the proportion of Actinobacteria was higher, and the proportions of Proteobacteria and Bacteroidetes were lower than in the samples from anthropogenically disrupted soils. Verrucomicrobia bacteria and Thaumarchaeota archaea were not found in the forming soils of the Kulyurtau and Tubinsky quarries, although in all other samples, there was a significant content of representatives of these types. Soil formation was observed at the Kulyurtau and Tubinsky mines, with a self-restoration period of more than 30 years. The microbial communities of the forming soils were similar in species richness to the background soils, and the alpha diversity showed a high level of dispersion, although the beta diversity had a different clustering, but the absence of Verrucomicrobia and Thaumarchaeota phyla in the samples from both sites indicates the underdevelopment of new soils compared with the natural background. Agrochemical indicators showed a dependence on the type of growing vegetation and the degree of anthropogenic load, and the correlation with the microbial composition of soils was traced poorly.

“…Initially, microbiomes of young soils are abundant in Chloroflexi and Cyanobacteria, photosynthetic bacteria which can survive with limited number of nutrients ( Gladkov et al, 2019 ). Quite rapidly after development, however, copiotrophic bacteria populate these soils ( Kimeklis et al, 2020 ).…”

Rendzic Leptosols are intrazonal soils formed on limestone bedrock. The specialty of these soils is that parent rock material is more influential in shaping soil characteristics than zonal factors such as climate, especially during soil formation. Unlike fast evolving Podzols due to their leaching regime, Leptosols do not undergo rapid development due to the nature of the limestone. Little is known how microbiome reflects this process, so we assessed microbiome composition of Rendzic Leptosols of different ages, arising from disruption and subsequent reclamation. The mountains and foothills that cover much of the Crimean Peninsula are ideal for this type of study, as the soils were formed on limestone and have been subjected to anthropogenic impacts through much of human history. Microbiomes of four soil sites forming a chronosequence, including different soil horizons, were studied using sequencing of 16S rRNA gene libraries and quantitative PCR. Dominant phyla for all soil sites were Actinobacteria, Proteobacteria, Acidobacteria, Bacteroidetes, Thaumarchaeota, Planctomycetes, Verrucomicrobia and Firmicutes. Alpha diversity was similar across sites and tended to be higher in topsoil. Beta diversity showed that microbiomes diverged according to the soil site and the soil horizon. The oldest and the youngest soils had the most similar microbiomes, which could have been caused by their geographic proximity. Oligotrophic bacteria from Chitinophagaceae, Blastocatellaceae and Rubrobacteriaceae dominated the microbiome of these soils. The microbiome of 700-year old soil was the most diverse. This soil was from the only study location with topsoil formed by plant litter, which provided additional nutrients and could have been the driving force of this differentiation. Consistent with this assumption, this soil was abundant in copiotrophic bacteria from Proteobacteria and Actinobacteria phyla. The microbiome of 50-year old Leptosol was more similar to the microbiome of benchmark soil than the microbiome of 700-year old soil, especially by weighted metrics. CCA analysis, in combination with PERMANOVA, linked differences in microbiomes to the joint change of all soil chemical parameters between soil horizons. Local factors, such as parent material and plant litter, more strongly influenced the microbiome composition in Rendzic Leptosols than soil age.

Russian North-West is the region with extremely high diversity of superficial mining wastes, deposited in form heaps and hills. These substrata are potentially dangerous for environments and. therefore, should be reclaimed. One of the most effective way of utilization of mineral wastes is to incorporate them to natural processes of revegetation and to initialize the priming of initial soil formation process. Thus, we have investigated microbial processes in very initial superficial ecosystems of numerous heaps of pre quaternary materials of former abandoned and recently explored quarries. The research question of this study: what groups of microorganisms we do have on the surface of mining mineral wastes and are we able to qualify their role in further recycling of mineral waste to natural processes, including pedogenesis and ecogenesis of terrestrial ecosystems. The great variation of taxonomy composition of microbiome composition was revealed. At the same time, some phylums of microorganisms were dominant in all revegetated heaps investigated - Proteobacteria, Actinobacteria, Acidobacteria, Bacteroidetes, Chloroflexia, Verrucomicrobia. They could be considered as a core components of very initial soil microbiome. Primary data have showed the increasing of microbial biodiversity with timing rate of waste exposure on surface.
