With the combination of incubation test and field experiment,the effects of the new nitrification inhibitor 3,5-dimethylpyrazole on urea-N transformation and NO~-_3-N leaching loss from corn field were studied.

Three Hu sheep(35±5)kg fitted with permanent ruminal cannulas,proximal duodenal T-shaped cannulas were used to investigate the effects of three different dietary protein levels on pH,NH_3-N and Urea-N in gastrointestinal tract.

The excretion of nitrite-N,urea-N and organic-N were increased in a pHdependent m.
