Inhibition of Nitrification by Acetylene¹

ABSTRACT

The effect of C₂H₂ on nitrification in soils was determined to evaluate the use of C₂H₂ in field and laboratory denitrification studies. The presence of as little as 0.1% (vol/vol) C₂H₂ completely inhibited nitrification. The effect of C₂H₂ was reversible, but an 8- to 10-day period was required before nitrification returned to the rate in the control. The results suggest that the C₂H₂ approach must be limited to those experiments in which either only nitrate fertilizers are used or where nitrification is assumed complete before denitrification commences.
