Conclusion• Stand age may not be the factor that affects the foliar cation
concentrations for most species
• Natural heterogeneity of soil nutrients may affect foliar cation
concentrations ( PC (Ca), AB(Ca, Mg), RM (Ca), SM(Ca), WB(Ca, Mg),
YB(Ca)), even in a small scale.
• Soil nutrients availability in the 0-10cm may be the best predicator of
foliage cation concentrations

Future plan
• We need more soil data!
