Abstract

This study analyzed and compared the physicochemical characteristics of topsoil and subsoil of Grade 1 soil from an igneous rock area on the ecological and nature map. The water content and pH of the collected soil samples were measured, and X-ray fluorescence and X-ray diffraction analyses were performed. The results showed that the water content of the topsoil was higher than that of the subsoil, and its pH was more acidic than that of the subsoil. According to the X-ray fluorescence analysis results, sample I9 was closest to kaolinite, while sample I7 was most distant from kaolinite. All other samples were located between samples I7 and I9. The X-ray diffraction analysis showed that the average content of clay minerals was higher in the topsoil than in the subsoil. The most notable clay minerals produced included illite, vermiculite, kaolinite, chlorite, and gibbsite. The results of this study will be used as a basic data for topsoil restoration to convert subsoil into topsoil.

본 연구는 화성암 지역의 생태 ‧ 자연도 1등급 토양의 표토와 심토를 채취하여 물리화학적 특성에 대해 분석하고 비교하는 것이 목적으로, 채취한 토양시료를 대상으로 함수율과 pH를 측정하고 X-선 형광분석 및 X-선 회절분석을 실시하였다. 연구결과, 함수율은 표토가 심토보다 높게 측정되었고 pH는 표토가 심토보다 더 산성으로 측정되었다. X-선 형광분석 결과, I9 시료가 카올리나이트와 가장 가까운 위치에 도시되었고 I7 시료가 카올리나이트와 가장 먼 위치에 도시되었으며, 그 외 시료들은 모두 I7 시료와 I9 시료의 사이에 위치한다. X-선 회절분석 결과, 점토광물의 평균 함량은 표토가 심토보다 높게 나타났으며 대표적으로 산출되는 점토광물로는 일라이트, 버미큘라이트, 카올리나이트, 녹니석, 깁사이트 등이 있다. 본 연구에서 얻은 결과는 향후 심토의 표토화를 위한 표토 복원 시 기초자료로 활용될 것으로 기대된다.
