Biomass of microbial communities in catenas of virgin and arable chernozems and gray forest soils

The biomass of microbial communities was studied in catenas virgin chernozems and dark-gray forest soils within the "Belogor'e" natural reserve vicinal arable developed same geomorphological lithological conditions. Living active estimated from point phospholipid content respiratory responses cells to glucose amendment respectively. In catena chernozem northern exposure, community changed slightly, while southern a decrease observed soil on lower part slope. opposite trend accumulation towards slope chernozems. gray soils, did not differ watershed part, but distinctly decreased middle catena. agro-gray tended increase both plowing has led living biomass.
