The influence of Black Sea deep-water organo-mineral sediments (sapropels) on the quantities of basic for soil fertility trophic groups of microorganisms at cinnamon рseudopodzolic soil (Planosol) was investigated. The study was conducted in conditions of pot experiments with cultivating oriental type tobacco. Sapropels were added in an amount of 30 g / kg dry samples for microbiological analysis from rhizosphere zone of tobacco plants were taken. | Microbiological characteristic of cinnamon Рseudopodzolic Soil Planosol at using of black sea deep-water sediments Sapropels
