Field experiments demonstrate that tailored fertiliser strategies reduce ammonia emissions in maize, suggesting a path to enhance sustainability.

Key Points

This research aims to explore how blending controlled-release urea with different maize varieties can reduce ammonia emissions and improve nitrogen use efficiency.
Conducted a two-year field experiment on summer maize in North China Plain.
Evaluated four nitrogen treatments: conventional urea and combinations of controlled-release urea with conventional urea.
Examined two maize varieties: early-maturing (JNK728) and late-maturing (ZD958).
Utilized structural equation modeling to identify the underlying mechanisms impacting ammonia emissions.
N180C1 and N180C2 treatments increased grain yield for JNK728 by 10%-17.4% and ZD958 by 5.5%-24.5%.
N180C1 reduced ammonia emissions by 23.52%-23.56%, enhancing sustainability by 154.11% for JNK728.
N180C2 achieved a 23.62%-27.83% reduction in ammonia emissions and a 162.63% improvement in sustainability for ZD958.
