Carbon, nitrogen, and phosphorus stoichiometry of organic matter in Swedish forest soils and its relationship with climate, tree species, and soil texture
Abstract ∘ N. The soils are a representative subsample of Swedish forest soils with a stand age > 60 years that were sampled for the Swedish Forest Soil Inventory. We found that the N stock of the organic layer increased by a factor of 7.5 from - ∘ C mean annual temperature (MAT), which is almost twice as much as the increase in the organic layer stock along the MAT gradient. The increase in the N stock went along with an increase in the N: P ratio of the organic layer by a factor of 2.1 from - ∘ C MAT (R 2 = 0.36, p < 0.001). Forests dominated by pine had higher C: N ratios in the organic layer and mineral soil down to a depth of 65 cm than forests dominated by spruce. Further, also the C: P ratio was increased in the pine-dominated forests compared to forests dominated by other tree species in the organic layer, while the C: OP ratio in the mineral soil was not elevated in pine forests. C, N, and OP contents in the mineral soil were higher in fine-textured soils than in coarse-textured soils by a factor of 2.3, 3.5, and 4.6, respectively. Thus, the effect of texture was stronger on OP than on N and C likely because OP adsorbs very rigidly to mineral surfaces. Further, we found that the P and K concentrations of the organic layer were inversely related to the organic layer stock, while the N: P ratio was positively related to the organic layer stock. Taken together, the results show that the N: P ratio of the organic layer was most strongly related to MAT. Further, the C: N ratio was most strongly related to dominant tree species even in the mineral subsoil. In contrast, the C: P ratio was only affected by dominant tree species in the organic layer, but the C: OP ratio in the mineral soil was hardly affected by tree species due to the strong effect of soil texture on the OP concentration.
