금산지역 토양별 화학적 특성과 주요 용존성분

This study is for know chemistry of the representative soils from Keumsan, its relationships with dissolved compositions, and its absorption relationships within the flora. It has been done for two comparisons: 1) phyllite, shale and granite(PSG), and 2) granite and coal bearing shale(GC). Among the soil leachate of the PSG, cations are mainly low in the phyllite area while anions are mainly low in the granite area. In the soil compositions, Ca and Mg of the beans are high and Na is high in the granite area while Ca and Na of the perilla are high in the granite area and Mg is high in the phyllite area. In th both species, Na for the granite area and Mg for the phyllite area are high while Ca for the shale area is low. Among the flora, shale area shows low Ca and Mg contents while granite area shows slightly high Na contents, regardless the species. Compared with beans, perilla is low in the Mg and high in the Na contents. These relationships show that the contents of the soil leachate do not reflect absorption within the flora. Among the soil leachate of the GC, shale area is high in the most of the elements. Especially, SO$_4$ is over 15 times high In the phyllite area. In the soil, granite area shows high Ca, Na and low Mg contents. In the flora, the Miscanthus sinensis shows high Ca and Mg contents in the granite area while the Artemisia vulgaris shows high Ca, Ca and Mg contents in the shale area. These relationships for contents of the flora and soil leachate suggest that the flora has a different absorption according different species.
