        경상북도 문경시 폐탄광 산림복구지 토양의 화학적 특성

        정문호(Mun Ho Jung),심연식(Mun Ho Jung),김태혁(Mun Ho Jung),오지영(Ji Young Oh),정영상(Yeong Sang Jung) 한국토양비료학회 2012 한국토양비료학회지 Vol.45 No.5

        The objectives of this study were to investigate soil chemical properties for forest rehabilitation and suggest design and management in abandoned coal mine areas in Mungyeong, Gyeongsangbuk-do. Total study sites were 10 sites, and soil analysis particular were soil pH, TOC, total-N, C/N ratio, A.v. P₂O5, and CEC. Because most of study sites showed soil pH from 5.0 to 7.0, it seems that soil pH does not affect growth of vegetation. But soil pH in Danbong1 was acidic (pH 4.6), so it is needed to improve with ameliorant such as limestone. Most of study sites is necessary to manage for organic matter and Nitrogen, because there sites showed lower value of TOC and total-N than general forest. The values of A.v. P₂O5 and CEC were good in most of study sites, so it seems that they do not have effect on vegetation growth. All of soil factors has no regression according to elapsed time after rehabilitation. TOC, total-N and A.v. P₂O5 among soil properties have positive relationship between each other. It is necessary to fertilizer for organic matter and Nitroge because of value in TOC, total-N and C/N ratio. The results of this study were analyzed only one time. So, long-term monitoring for soil properties is important for the correct forest rehabilitation and management.

        전라남도 화순군 폐탄광 산림복구지 토양의 화학적 특성

        정문호(Mun Ho Jung),심연식(Yon Sik Shim),김태혁(Tae Heok Kim) 한국토양비료학회 2011 한국토양비료학회지 Vol.44 No.6

        The objectives of this study were to investigate soil chemical characteristics for forest rehabilitation and suggest management in abandoned coal mine areas in Hwasun-gun, South Jeolla Province. Total study sites were 8 sites, and soil analysis particular were soil pH, TOC, total-N, C/N ratio, Avail. P2O5, and CEC. Average soil pH was 5.8 (4.7~6.4). Average contents of TOC, total-N and C/N ratio were 1.1% (0.2~2.0%), 0.08% (0.02~0.13%) and 15.0 (7.9~31.4), respectively. Average Avail. P2O5 was 8.3 mg kg<SUP>-1</SUP> (2.7~15.0) and Average CEC was 13.7 cmolc ㎏<SUP>-1</SUP> (9.9~18.5 cmolc ㎏<SUP>-1</SUP>). Soil pH was decreased according to elapsed time from forest rehabilitation, while TOC, total N and CEC were increased. Av. P2O5 did not show any relationship with elapsed time. Soil pH was stable comparing with general forest soil in South Jeolla Province (5.1), while contents of TOC and total N were lower than general forest soil in South Jeolla Province (4.9% and 0.18%, respectively). Therefore, sustainable managements such as fertilization for TOC and total N are necessary for good rooting and growth of vegetation.
