by Wentao Wu The conflict between food production and environmental protection calls for climate-smart agricultural solutions. This study investigated data-driven climate-smart strategies for optimizing cropping systems and nitrogen management to increase crop yield and cut greenhouse gas emissions in China’s Beijing-Tianjin-Hebei (BTH) region, which is grappling with pronounced climatic and environmental challenges.
The study evaluated three cropping systems: spring maize monoculture (M), winter wheat followed by summer maize double-cropping (WM), and a triple-cropping system encompassing winter wheat, summer maize, and spring maize (WMM). Additionally, four nitrogen fertilization treatments were assessed to understand their impacts.
The crop climate resilient index was created to identify the optimal management practices. Leveraging the Agricultural Production Systems sIMulator (APSIM) model, this study simulated the daily dynamics of crop yields, soil organic carbon (SOC) content, and nitrous oxide (N₂O) emissions over a comprehensive 40-year period spanning from 1981 to 2020.
The findings revealed intriguing insights into SOC dynamics and nitrogen fertilizer efficiency.
