COMPLEX BIOLOGICAL PREPARATIONS BASED ON AUTOCHTHONIC SOIL MICROORGANISMS
A comparative assessment of the effectiveness of the action of a consortium of microorganisms consisting of autochthonous diazotrophic (Azotobacter chroococcum 5V, Pseudomonas brassicacearum 26W) and phosphate-mobilizing bacteria (Achromobacter xylosoxidans 5F, Sphingobacterium multivorum 6 F) with the industrial biological product Azolen, based on the strain Azotobacter vinelandii IB-4, was carried out. Consortium compositions with natural minerals and their nanostructured counterparts have been created. The maximum energy of germination and germination of seeds of wheat of the Kazanskaya 560 variety was established when using a consortium of microorganisms with zeolite and nanostructured water-zeolite suspension. The maximum length of the root was noted when using a consortium of microorganisms, and the length of the seedling - with a nanostructured water-diatomaceous suspension. The best indicator in terms of root and seedling biomass was established in the variant with a consortium of microorganisms and nanostructured water-diatomaceous earth, more effective for improving the germination and growth of spring wheat compared to the industrial biological product Azolen.
