“…Moreover, the discovery of Blastocatellia in the lucuma rhizospheric soil highlights its speci c adaptation to this environment's unique conditions. This nding, supported by prior research indicating Blastocatellia's abundance in bulk soils, underscores the importance of understanding microbial diversity in speci c environments such as the lucuma rhizosphere [76,77]. Additionally, the identi cation of Planctomycetes in the 30 cm rhizosphere of the lucuma plant [78], known for their ability to degrade complex heteropolysaccharides, further emphasizes the intricate interplay between microbial communities and soil health.…”

Characterization of soil microbial community at different depths is essential to understand their impact on nutrient availability, soil fertility, plant growth and stress tolerance. We analyzed the microbial community at three depths (3 cm, 12 cm, and 30 cm) in thenative fruit trees Annona cherimola (cherimoya ) and Pouteria lucuma (lucuma), their fruits are rich in vitamins, minerals, and antioxidants. We used Pac Bio HiFi, along-read high-throughput sequencing to explore the composition, diversity and functions of bacterial communities in the rhizosphere of cherimoya and lucuma at different soil depths. Bacterial diversity, encompassing various phyla, families, and genera, changed with depth. Notable differences were observed in the alpha diversity indices, especially the Shannon index. Beta diversity also varied based on plant type and depth. In cherimoya soils, positive correlations with Total Organic Carbon (TOC) and Cation Exchange Capacity (CEC) were found, but negative ones with certain cations. In lucuma soils, indices like the Shannon index showed negative correlations with several metals and specific soil properties. We proposed that differences between the plant rhizosphere environments may explain the variance in their microbial diversity . This is a solid starting point for understanding the impact of microorganisms in different soil depths and their influence on cro p growth and quality.

“…The work was carried out at the station of the Siberian Federal Scientific Centre of Agrobiotechnologies of the Russian Academy of Sciences (Siberian Scientific Research Institute of Fodder Crops), where studies on the effect of phytomelioration on the properties of solonetz soils have been being carried out since 1987 [9][10][11]. The station is located in the Baraba forest-steppe of the Novosibirsk region.…”

40% of the territory of Western Siberia is occupied by solonetzes, used mainly for growing forage grasses. The phytomeliorative effect of yellow sweet clover (cultivated in crop rotation at the Siberian Federal Research Center of Agrobiotechnologies (SFSCA) of the Russian Academy of Sciences (RAS) for 31 years), as well as post crop rotation grassing with a mixture of brome and alfalfa (the mixture was sown after twenty years of crop rotation) on the microflora of medium solonetz was studied. It is shown that the cultivation of phytomeliorants has led to an increase in the representation of classes and orders of bacteria in the microbiome of the medium solonetz, associated with nitrogen fixation and mineralization activity of the soil in relation to nitrogen-containing substances. In the post crop rotation grassing variant, a low bacterization of the soil with Verrucomicrobia and a high, as in virgin soil, Acidobacteria were found.

Vast areas of Western Siberia (about 40%) are occupied by saline soils. Solonetzic agricultural lands are mainly used for growing perennial grasses - phytomeliorants. To increase the yield of fodder crops on solonetz lands, specialists of the Siberian Research Institute of Fodder Crops in the 80s of the last century developed phytomeliorative crop rotations. The article considers the effect of grassing phytomeliorative crop rotations with a mixture of brome (Bromus inermis Leyss.) and alfalfa (Medicago varia Mart.) on the microflora of meadow solonetzes (hydromorphic) (Gleyic Solonetz Albic) (for 13 years). It is shown that post-rotational grassing led to a significant desalinization of the upper soil horizon and a decrease in its alkalinity, as well as to an improvement in the water-air regime of solonetzes. Long-term cultivation of fodder crop rotations and subsequent grassing formed a specific soil microbiome, characterized by taxonomic diversity of microorganisms and a greater proportion of copiotrophs in the dominant phyla, which indirectly indicates an increase in the carbon content and nitrogen available to plants in the phytomeliorated solonetz.
