Résumé :
|
Anaerobic conditions are formed within natural soil aggregates of 0.4-1 cm diameter in chernozem. These conditions suffice to maintain the process of denitrification even in a normal oxygen atmosphere (oxygen concentration 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 and actinomyces-bacteria associations are found in the centers of aggregates as compared with their periphery.
