Description
Summary:Aim Fine roots play an important role in biogeochemical cycling in terrestrial ecosystems. However, our understanding of large scale biogeographical patterns and drivers of fine‐root C:N:P stoichiometry is extremely limited. Location China. Methods We compiled data for fine‐root carbon (C), nitrogen (N) and phosphorus (P) concentrations at 165 sites across China to explore large‐scale biogeographical patterns and drivers of fine‐root C:N:P stoichiometry. Results The geometric means of fine‐root C, N, and P concentrations were 448.81, 10.73, and 0.9 mg/g, respectively, whereas C:N, C:P, and N:P ratios were 41.84, 508.32, and 11.73, respectively. The fine‐root elemental concentrations and their ratios varied widely among plant groups and biomes, and showed clear latitudinal and longitudinal trends, as a consequence of differences in climate, soil, and plant type. However, plant type was the largest contributor to the total variance in fine‐root C, N, and P and their ratios compared to climate factors or soil features. Main conclusions The data reveal the existence of broad biogeographical patterns of fine‐root C:N:P stoichiometry in China. These results advance our knowledge about the biogeochemical cycling of fine roots.
