AbstractFine-root nitrogen (N) and phosphorus (P) concentrations play an important role in driving ecological processes such as nutrient cycling in terrestrial ecosystems. Previous studies have demonstrated that the N versus P scaling relationship for fine roots (−1, 1.01 mg g−1, and 15.14, respectively. N and P concentrations, N:P ratios, and the numerical values of the N versus P scaling exponents differed significantly within and across the different fine-root classes. The numerical values of absorptive roots N versus P scaling exponents varied within plant functional groups (e.g., life-form, phylogenetic and mycorrhizal groups). The numerical values of absorptive roots scaling exponents declined from 0.89 in boreal regions to 0.61 tropical regions. These results indicate that fine roots ( © 2021 Elsevier B.V.
