Soil nitrogen loss through NH3 volatilization and N2O emissions is a crucial issue in soil ecosystems. In this study, we explored the effects of biochar nitrification inhibitor DMPP (dimethyl-phenyl-piperazinium, inhibitor) vegetable soils under 60 200% WHC (water holding capacity). Five treatments were set: CK (control), urea (N), + (N C), DMPP), C DMPP). Results found that promoted ammonia both moisture conditions, with higher rate accumulation at WHC. maintained high NH4 +-N concentration increased volatilization, but effectively reduced emissions, especially The N treatment further significantly decreased cumulative compared to DMPP. QPCR results showed AOB (ammonia-oxidizing bacteria) copies treatment. Applying alone or by 50.0 45.7%, respectively. ammonia-oxidizing archaea (AOA) responded oppositely DMPP; AOA amounts during culture. At 60% WHC, greenhouse effect potential 39.0 43.2% lower than N, their GWP 13.8 0.08% N. Adding soil's water contents. conclusion, using inhibitors combination more effective reducing active emissions.
