The paper contains a description of the method, which allows assessing soil suitability for growing improved seed potatoes by the totality of microbiological characteristics of the soil. An indicator of the level of suppression of the soil microbial community is proposed as the main indicator of soil suitability, which is based on the species diversity of the soil microorganisms and its total suppressive activity against potato pathogens, in particular Fusarium solani . Among the six soil sites tested by this method at one of potato farms in Tomsk Region, virgin land sites, a site that had been in a fallow state for a long time, and an arable site that had been fertilized for several years were recognized as the most suitable for growing improved seed potatoes.
