| The purpose of this paper is to study the influence of denitrification in soil under different conditions, which inclulude inaerobic intensity, pH value, organic matter contents and temperatue. Data obtained show that velocity of denitrification is logarithmically proportional to time. Adjusting pH values and constantly supplying organic matter will keep continuity of denitrification. N2O, the product of denitrification. is quantified by using gas-charomatography and ethyne is used as an inhibitor. The results of the experiment describe the regularity of denit-tification mechanism in soil. |
