Claims5
A method for suppressing the nitrification of ammonium nitrogen in growth media which comprises treating said growth media with a compound having the formula ##STR2## wherein X is hydrogen, or R'CO--;
- wherein R' is alkyl of 1 to 4 carbon atoms or phenyl and R" is 3, 4 or 5 ring substituted chloro or alkyl of 1 to 4 carbon atoms and n is 0, 1 or 2.
A fertilizer composition useful for suppressing the nitrification of ammonium nitrogen in growth media and for preventing rapid loss of ammonium nitrogen therefrom comprising a reduced nitrogen fertilizer and a compound having the formula ##STR3## wherein X is hydrogen, or R'CO--;
- wherein R' is alkyl of 1 to 4 carbon atoms or phenyl and R" is 3, 4 or 5 ring substituted chloro or alkyl of 1 to 4 carbon atoms and n is 0, 1 or 2.
