Abstract

Abstract

En 中文
• Canopy structure compensation mitigates leaf-to-canopy scale mismatch in N sensing. • Integrating thermal-time context stabilizes N diagnosis across diverse growth stages. • Diagnosed N status during the V9-R1 window strongly correlates with relative yield. • Provides quantitative diagnostic information to support in-season N management decisions.
