Abstract
Anaerobic conditions are formed within natural soil aggregates of 0.4- 1 cm diameter in chernozem. These conditions suffice to maintain the p rocess of denitrification even in a normal oxygen atmosphere (oxygen c oncentration 20%). Emission of nitrous oxide from aggregates increases with their diameter. More cells of bacteria and actinomyces mycelium and more intense accumulation of nitrous oxide by bacteria cultures an d actinomyces-bacteria associations are found in the centers of aggreg ates as compared with their periphery.
