Visual indicator of the relationships the between index of biological activity of soils in agrocenoses of leguminous crops and bacterization of plants (p < 0.05): a – Rhizobofit, b – Rhizobofit, Phosfoenterin, Biopolicyd; c – Cyano-rhizobial consortium; d – Rhizobofit, Arbuscular mycorrhizal fungi. Notes: the number of: Amt – bacteria which are using mineral forms, Amf – ammonificators, Olg –oligotrophic bacteria, NitF– nitrogen-fixing bacteria, Phm – phosphate-mobilizing bacteria, Cel – cellulose-decomposing bacteria, Mcm – micromycetes, Actm – actinomycetes, Sp – bacteria which form spores; PFA – polyphenoloxidase activity, PA – peroxidase activity, Kt – activity of catalase, Inv – activity of invertase, PhA – activity of phosphatase, CO₂ – the intensity of the release of carbon dioxide, *Kmin – coefficients of mineralization, *Iolg – coefficients of oligotrophy, *Kmtos – coefficients of microbial transformation of organic matter, *CCG – coefficients of humification.
