<p dir="ltr">Declining atmospheric nitrogen (N) deposition does not necessarily mean that the effects of historically elevated<b> </b>N inputs on carbon cycling will disappear rapidly.
Description
However, The legacy effects of historical N addition on forest greenhouse gas fluxes following N cessation remain poorly understood. We conducted this study in a cold-temperate coniferous forest in China that had previously received high N addition at 60 kg N ha<sup>-1</sup> yr<sup>-1</sup>.
We measured soil CO<sub>2</sub> and CH<sub>4</sub> fluxes during the growing season in the first, third, and fifth years after N cessation and examined their relationships with soil enzyme activities and elemental contents. Historical N addition produced persistent but asynchronous legacy effects on different greenhouse gas fluxes. In the first and third years after N cessation, CO<sub>2</sub> flux increased significantly by 37.2% and 57.2%, respectively, but this effect disappeared by the fifth year.

In contrast, historical N addition persistently suppressed soil CH<sub>4</sub> uptake throughout the five years following N cessation. Post-cessation CO<sub>2</sub> emissions were mainly positively correlated with phosphatase activity and total N content, whereas CH<sub>4</sub> uptake was primarily positively correlated with N-acetyl-β-D-glucosaminidase activity and negatively correlated with phosphatase activity and total N content.
These contrasting relationships suggest<b> </b>that these two greenhouse gas fluxes were governed by distinct microbial nutrient-acquisition strategies. Our findings highlight the need for biogeochemical models to account for N legacy effects and their asynchronous recovery among greenhouse gas fluxes to improve predictions under declining atmospheric N deposition.</p>
