摘要:
Certain metal salts of certain substituted pyrazole compounds are employed as the active nitrification inhibitor in the presence of reduced nitrogen fertilizers. Compositions containing these salts can be applied to the surface of soil and can remain on said soil surface for up to 3 days or more without incorporation into the soil and retain at least about 70 percent of the pyrazole in the salt in the composition.
