Does the nitrification inhibitor dicyandiamide affect the abundance of ammonia-oxidizing bacteria and archaea in a Hap-Udic Luvisol?

To date, there are several studies on the responses of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) to nitrification inhibitors, but only a limited number of observations are available for higher than regular application rates. Here, we report the results of a study investiga...
