Description

Distribution and turnover of phosphorus, nitrogen, potassium, calcium, magnesium, sodium and BHC in a low-land forest ecosystem were examined in Taiwan (Lake Chengching Kaohsiung County, and Kenting Park Ping Tung County, and Taoyuan Village Taitung County) and in Japan (Kamiuracho Minamiamabe County, Oita Pref.) from February to November, 1985. The results were as follows. The contents of P, K and Mg in the A-layer of soil, and P and K in the H-layer in Japan were higher than those in Taiwan, but the content of Ca in the L-layer of soil in Japan was lower than that in Taiwan. The contents of P in plants and N in trees in Taiwan and the contents of six kinds of elements (P, N, K, Ca, Mg, Na) in insects in Taiwan were higher than those in Japan. Furthermore, BHC residues in the A, H and L-soil-layers in Japan were higher than those in Taiwan. According to the distribution and turnover of P, N and Ca in the Taiwan ecosystem (Kenting Park Ping Tung County), the turnover of those three kinds of elements was more active in Taiwan than in Japan.
