The content of elements in the H- and F-soil layers (cryptomeria pure forest and cryptomeria, white cedar, andromeda and hydrangea mixed forest) was in the order of calcium > magnesium > sodium>potassium>nitrogen = phosphorus. On the otber hand, the content was in the order of K>N>Ca>Mg>Na = P for the herbs; N>Ca>K>Na = P for the trees. However, the content of N. K, P and Na (the content of each element was almost the same) was higher than that of Ca and Mg for insects. The content ofN, Mg and P in the herbs near the craters was high compared with that in areas at a lower elevation the amount of BHC residues decreased in the order of L-1ayer>F-1ayer>H-layer and the amount of BHC residues in trees decreased near the creaters.
