Short summary
We explored soil microbial respiration (Rh) kinetics of low-dose and long-term N fertilization in N-limited boreal forest in connection with CH4 and N2O fluxes and soil and tree C sinks. The insights show that N fertilization affects C retention in boreal forest soils by modifying Rh sensitivities to soil temperature and moisture. The key findings reveal that N-enriched soils exhibited reduced sensitivity of Rh to moisture, which contributed to enhanced soil C sequestration on an annual level.
