The content of calcium in the A-, H-, F- and L-soil layers was high, but that of phosphorus in the soil layers was low. While the content of nitrogen in the soil layers decreased in the lower layers, the sodium content tended to increase. The content of the six elements in plants was N>K>Ca> Mg>Na>p, in the descending order. The content of Ca, Mg, and Na in the forest ecosystem of Hokkaido was lower than that in Oita Pref. The content of P and N increased with the ecological niche of the food chain, while that of K and Mg tended to decrease. The content of P and N in the herbs of the damp plains was higher compared with that of the grassland in Oita Pref. The content of P, N, and K in Pteridophyta of the grassland was higher than that of the damp plains. BHC residues in the forest ecosystem of Iwamizawa decreased with the ecological niche of the food chain.
