“…In arable soil (AR), the largest number of microfungi (4.88×10 3 CFU/g) was observed in the topsoil horizon and then significantly (more than 10 times) decreased in profile. This is probably due to the most active involvement of the topsoil arable horizon in agricultural practices (fertilization, loosening, plowing) and, as a result, numerous breaks in the fungal mycelium by tillage tools, fragments of which give rise to colonies on nutrient media (Trzciński et al 2018). In the S-R zone soil, a gradual decrease in the number of microfungi was observed in the profile in following order: organic (O) > elluvial (Е) > illuvial (Bs).…”

A comprehensive study of the quantitative and qualitative parameters of soil microfungi, bacteria and algae communities in the Apatity city, located in the subarctic zone of Russia, was carried out for the first time. Urban soil samples were taken from various landuse zones (residential, recreational) and compared to arable and forest soils. In the residential zone, a decrease in the number of microfungi in the topsoil horizon to 1.1 thous. CFU/g compared to 22.7 thous. CFU/g in forest soil was revealed. In the residential zone, an increase was found in the number of saprotrophic bacteria to 7.8 million cells g-1 and oligotrophic to 10.9 million cells g-1 compared to 2.6 million cells g-1 and 1.8 million cells g-1 respectively in forest soils. In the recreational zone, the number of soil microorganisms was similar to that in the forest. A decrease in the species diversity of microfungi in the soil of the residential zone and an increase in the diversity of soil algae were revealed. Among the dominant species of fungi in urban soils, atypical species, including pathogenic ones for humans (Penicillium dierckxii, Stachybotris echinatus, Fusarium sp.), were found. In the algal community, diatoms, yellow-green algae, and cyanobacteria appeared in urban soils in comparison with forest soil. As a result of changes in the quantitative and qualitative indicators of soil microbial communities, a decrease in the enzymatic activity of soils has been noted. This may indicate a weakening of the ecosystem functions of urban soils and an increase in the degree of toxicity for living organisms and humans.

One of the key steps in plant micropropagation is rooting and acclimatization of microcuttings. The aim of the study was to investigate the suitability of commercial biopreparations, TotalHumus® and Bacterbase, to stimulate the growth of young fruit plants derived from in vitro propagation. TotalHumus® is made from brown coal. Bacterbase is a bacterial preparation containing Bacillus velezensis and Bacillus amyloliqefaciens (Skierniewickie Microorganisms) with antifungal properties that stimulates the growth and yielding of plants. Unrooted microshoots of strawberry ‘Grandarosaʼ and highbush blueberry ‘Chandlerʼ, and rooted in vitro microcuttings of hip rose ‘Konstancinʼ were planted in a peat substrate. Three weeks after planting ex vitro, the plants were treated with the biopreparations. Four times, at two-week intervals, the plants were drenched and simultaneously sprayed with mineral fertilizer 0.2% Hydrovit (control), 0.04% TotalHumus® and 0.03% Bacterbase, which were used separately or in combinations. In hip rose and strawberry, compared to the control, similar or better growth parameters of shoots and roots were observed after the use of TotalHumus® and/or Bacterbase. The plants were characterized by the highest fresh weight, longer shoots/runners and more shoots than in the control (mineral fertilization). In strawberry, root parameters were significantly improved by TotalHumus®, and in rose by Bacterbase. The use of both TotalHumus® and Bacterbase separately or in combination significantly reduced the occurrence of symptoms of rose leaf infection with powdery mildew. The biopreparations had no effect on highbush blueberry.
