Other claims from this paper (10)
- Observation Fine roots resorbed a mean 9.5% nitrogen.
- Association Fine root nitrogen resorption was much lower than leaf resorption of 72.8%.
- Intervention effect Chronic nitrogen addition reduced fine root nitrogen resorption efficiency only in young stands.
- Intervention effect Chronic nitrogen addition reduced fine root resorption proficiency across all ages.
- Association Leaf and fine root nitrogen resorption covaried synergistically.
- Association Fine root nitrogen acquisition was decoupled from leaf nitrogen resorption.
- Association Fine root nitrogen acquisition traded off with fine root resorption in young trees.
- Association Fine root nitrogen acquisition was synergistic with fine root resorption in mature trees.
- Mechanism The authors interpret young trees under nitrogen abundance as using a self-reliant acquisition strategy.
- Recommendation The authors recommend flux-based approaches to quantify nitrogen pathway contributions dynamically.
