This article presents the results from the development of a technology for producing biohumus from the feces of cattle and winter wheat straw in a biodynamic fermenter. Nitrifying agents are important for soil fertility, which is dependent on the intensity of the nitrification process. This group includes aerobic cellulose-destroying microorganisms, denitrifiers and sulfate-reducing bacteria. The ratio of these groups and their composition are changing. Therefore, the study of the quantitative ratio of microbial communities involved in the formation of biohumus was of considerable scientific interest. During the microbiological analyses, a large number of microorganisms were found to be involved in the decomposition of the organic compounds. Aminoautotrophic microorganisms represented the largest physiological group of microorganisms in the biohumus. The chemical composition of the biohumus was determined during the study and a sanitary microbiological analysis was performed. The content of gross forms of elements in the humic extract was also examined. The humic extract from the biohumus was a brown liquid with 15 g / l of humic acids, 5.0 g / l of fulvic acids, and gross forms of elements (potassium, phosphorus, nitrogen). The dry matter in the biohumus was 1.0% of the total composition and contained 0.1% nitrogen, 0.03% phosphorus P2O5 and 0.01% potassium K2O. It was found that high-quality organic fertilizer can be obtained using this technology. Keywords: biohumus, humic extract, chemical composition, sanitary-microbiological analysis, organic fertilizer

“…According to Maji et al (2017), application of humic substances derived from vermicompost stimulated microbial biomass carbon, microbial biomass nitrogen and CO 2 respiration. Another recent study demonstrated that application of humic substances originated from spent mushroom substrate to paddy field olocated at south eastern China showed a remarkable effect on improving soil organic carbon, alkali-soluble humic carbon, microbial biomass carbon and microbial biomass nitrogen (Li et al, 2020). In additional study, Til'ba and Sinegovskaya (2012) reported that humic acid supplementation to soybean either as seed coating or foliar spraying with sodium humate maximized nodules number and nitrogen-fixing efficiency, thereby increased the produced yield by about 22% relative to the control (without humic substances supplementation).…”

“…Moreover, some families of Basidiomycota have been confirmed to have enzymes that degrade complex macromolecular organic matter in the soil (Floudas, et al, 2012). When the soil carbon content increased, the abundance of Agaricomycetes significantly increased (Li, et al, 2020). Therefore, this might be the reason why Basidiomycota became the dominant fungus after the soil carbon content increased.…”

To compare the rhizosphere communities under Masson pine trees with different carbon sequestration abilities, we sampled three families of Masson pine that showed significant differences in their carbon sequestration ability and conducted high-throughput sequencing of the 16S rRNA and ITS in the corresponding soil samples. The diversity of rhizosphere soil microorganisms, the patterns of differences in relative abundance among the different samples and the responses of microorganisms to environmental factors were analyzed. There was no significant difference in the diversity of soil bacteria or fungi among the different samples from Masson pine families with different carbon sequestration abilities, but with the increase in carbon sequestration, the dominant phyla of bacteria and fungi changed. The dominant phylum of soil bacteria changed from Proteobacteria to Acidobacteria, and that of fungi changed from Ascomycota to Basidiomycota. In addition, we investigated the core microbial communities at the genus level among the different samples, and a significant portion of the core genera were involved in carbon metabolism. The microbial communities were greatly influenced by environmental factors such as soil carbon content, soil moisture and altitude. Soil fungi were more sensitive than soil fungi to the rhizosphere activity of Masson pine.
