Abstract Deciphering the linkage between ecological stoichiometry and ecosystem functioning under anthropogenic nitrogen (N) deposition is critical for understanding impact of afforestation on terrestrial carbon (C) sequestration. However, specific changes in above‐ versus belowground stoichiometric asymmetry with stand age response to long‐term N addition remain poorly understood. In this study, we investigated following a decadal three levels (control, no addition; low addition, 20 kg ha −1 year ; high 50 ) young, intermediate, mature stands temperate larch plantations ( Larix principis‐rupprechtii North China. We found that had both (leaf litter) (soil microbe) stoichiometry. contrast, resulted significant stoichiometry, which then diminished during development. Following 10 years inputs, young intermediate transitioned from state relative limitation co‐limitation by phosphorus (P), whereas plantation continued experience limitation. Conversely, soil microorganisms exhibited P all plantations. Broader niche differentiation (N trees, but microorganisms) input may have been responsible faster attainment homeostasis than Our findings provide stoichiometric‐based insight into operating mechanisms large C sinks forests, particularly stock asymmetry, highlight need consider role flexible when forecasting future forest sinks.
