Bioindication of desalination in grassed soil by microbiome diversity

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