摘要:In this study, we explored the role of biochar (BC) and/or urease inhibitor (UI) in mitigating ammonia (NH
3) and nitrous oxide (N
2O) discharge from urea fertilized wheat cultivated fields in Pakistan (34.01°N, 71.71°E). The experiment included five treatments [control, urea (150 kg N ha
−1), BC (10 Mg ha
−1), urea + BC and urea + BC + UI (1 L ton
−1)
