A. Stepanov ; N. Manucharova ; L. Polyanskaya | 1997Anaerobic 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 nitr[...]
