초록

The objectives of this study were to investigate soil chemical and microbiological characteristics in Yeongnam, Honam, Chungcheong and Kangwon for forest rehabilitation and management in abandoned coal mine areas. Average soil pH was 5.5 (4.2 ~ 8.1). Average contents of TOC, total N and available P2O5were 1.1% (0.1 ~ 2.6%), 0.08% (0.02 ~ 0.14%) and 16.1 ppm (3.4 ~ 63.1 ppm), respectively. Average CEC was 3.4 cmol kg-¹ and total no. of bacteria1 showed 4.9 × 1012 CFU g-¹. According to areas, soil pH was the highest in Kangwon (6.1), and Yeongnam (5.7), Honam (5.3) and Chungcheong (4.7), respectively.
TOC and total no. of bacteria showed no difference. Total-N was higher in order of Yeongnam (0.10%) >Chungcheong (0.08%) = Honam (0.07%) > Kangwon (0.06%), while Av. P2O5 Yeongnam (23.9 ppm) =Chungcheong (24.5 ppm) > Honam (10.9 ppm) = Kangwon (4.9 ppm). Yeongnam showed higher value in CEC (17.5 cmol kg-¹) than any other areas. Generally, soil characteristic of Yeongnam was better for vegetation growth than any other areas, while Kangwon was worse. According to elapsed time from forest rehabilitation, patterns of soil pH and CEC showed decrease according to time while TOC and total-N increased. There were no significant differences in Av. P2O5 and total no. of bacteria. Soil chemical characteristics in abandoned coal mine areas were disadvantageous for vegetation growth in comparison with general forest soils. Therefore, sustainable managements such as fertilization are necessary for good rooting and growth of vegetation.
