Abstract
An ‘electrolytic’ respirometer was used to study the effects of oxygen, moisture and glucose on denitrification in undisturbed cores from a solodized solonetz B horizon. Under the experimental conditions, nitrous oxide present after 144 h was a reasonable index of total denitrification. Nitrous oxide evolution was positively correlated with moisture, quantity of added glucose, and negatively correlated with per cent oxygen. With glucose present, denitrification proceeded at high oxygen and moderate moisture levels, but was most rapid at low oxygen and high moisture. At low oxygen content, denitrification increased with increasing water content. In horizons with high potential denitrifying activity, denitrification could occur under field conditions at moderate aeration and moderately high moisture contents.
