The measurement of nutrient elements N, P, SiO2, K, Ca, Mg, Cu, Fe, Zn and Mn in rainfall, through-fall of canopy and shrub layer, and dripping of herb layer in Cinnamomum camphor plantation showed that the concentrations of test elements in rainfall varied with different month, and their monthly average concentrations decreased in the sequence of Ca>SiO2>Zn>NH4-N>K> NO3-N>Fe>Mg>Mn>P>Cu. The concentrations of these elements in the through-fall of canopy and shrub layer and in the dripping of herb layer varied in the same way and changed seasonally, most of which w...
