Introduction This study examined the impact of biochar application on agricultural productivity and greenhouse gas emissions in irrigated regions northern Xinjiang. The objective this was to assess nitrogen fertilizer levels soil respiration rate, enzyme activity, spring wheat yield. Materials methods experiment employed a randomized block design comprising two (N1: 300 kg·hm -2 N2: 255 ) four (B0: 0 , B1: 10×10 3 B2: 20×10 B3: 30×10 ). resulted eight groups (N1B0, N1B1, N1B2, N1B3, N2B0, N2B1, N2B2, N2B3), each replicated three times. Results discussion findings indicated that N2B2 group exhibited reduction CO 2 emissions, with cumulative decrease 4.42% compared N2B0 control. and/or fertilizer, particularly combination, observed increase urease, sucrase, catalase activities. yield 8301.35 representing 22.1% over N1B0 group. improvement attributed capacity regulate water content variability, stabilize aggregate composition, mitigate organic carbon mineralization, reduce farmland emissions. Furthermore, biochar’s fixation provided essential nutrients for microorganisms, thereby enhancing enzymatic reactions promoting crop growth. Conclusion In conclusion, regime determined be optimal approach cultivation Xinjiang, resulting enhanced mitigation Nevertheless, further investigation its long-term is recommended.
