Table 4 Leaf nitrogen (LN) and phosphorus (LP) concentrations and N:P ratio (L N:P), and the soil nitrogen (SN) and phosphorus (SP) concentrations and soil N:P ratios (S N:P) measured in the five S. superba forest sites (means with S.E. in parentheses, n = 30 for plant samples and n = 5 for soil samples)
From: Nitrogen and phosphorus stoichiometry of Schima superba under nitrogen deposition
