This study introduces a plant-soil mesocosm system capable of continuously measuring N2, N2O, and CO2 fluxes during plant cultivation. Through a 33-day experiment with germinated wheat plants, the system's effectiveness in assessing soil denitrification dynamics and CO2 respiration rates is demonstrated, showcasing its potential for advancing environmental research.
