토석 채취 후 식생복구지의 토양 특성은 복구 식생의 생육에 중요하다. 본 연구는 토석 채취 후 식생복구지와 인접 소나무 및 굴참나무 임분을 대상으로 0∼10cm, 10∼20cm, 20∼30cm 깊이에 토양의 물리·화학적 특성을 조사하였다. 토양용적밀도와 토양 pH는 식생복구지가 소나무나 굴참나무 임분에 비해 유의적으로 높았으나(P<0.05), 유기탄소와 전질소농도는 인접 산림지에 비해 낮았다. 유효 인은 0~10cm 깊이에서 식생복구지 와 산림지 간 유의적인 차이가 없었으나, 교환성 칼슘은 식생복구지가 인접 산림지에 비해 유의적으로 높게 나타났다. 토양 유기 탄소저장량은 식생복구지가 9,896 kg C ha-1로 소나무 임분 131,368 kg C ha-1나 굴참나무 임분 154,381 kg C ha-1에 비해 유의적으로 낮았으며 질소저장량도(식 생복구지: 2,406 kg N ha-1; 소나무: 10,496 kg N ha-1; 굴참나무: 8,081 kg N ha-1) 유사한 경향을 보였다. 그러나 인, 포타슘, 마그네슘 저장량은 식생복구지와 인접 산림 간 유의적인 차이는 없었다. 한편, 칼슘저장량은 식생복구지가 8,998 kg Ca ha-1로 소나무 임분 697 kg Ca ha-1나 굴참나무 임분 660 kg Ca ha-1에 비해 유의적으로 크게 나타났다. 본 연구 결과에 따르면 토석 채취 후 식생복구지는 토양용적밀도와 토양 pH를 낮추고 유기물의 증가와 질소 시비 같은 양분관리가 필요한 것으로 나타났다.

This study was performed to determine soil property of the quarry restoration area and adjacent forests in Tongyeong-si, Gyeongsangnam-do. Soils at 0-30cm (0-10cm, 10-20cm, and 20-30cm) depth were collected from the quarry restoration area and adjacent pine and oak forests to compare soil property. Soil bulk density and soil pH at three soil depths were significantly higher in the quarry restoration area than in the adjacent pine and oak forests. Soil organic carbon (C) and nitrogen (N) concentrations were significantly higher in the adjacent pine and the oak forests than in the quarry restoration area. However, the phosphorus (P) concentration at 0-10cm depth were not significantly different among the three treatments. The exchangeable potassium (K) were lower in the quarry restoration area than in the adjacent pine and oak forests, whereas exchangeable calcium (Ca) was significantly higher in the quarry restoration area than in the forests. Soil C and N stocks were significantly higher in the adjacent pine (131,368 kg C ha-1; 10,496 kg N ha-1) and the oak (154,381 kg C ha-1; 8,081 kg N ha-1) forests than in the quarry restoration area (9,896 kg C ha-1; 2,406 kg N ha-1). The stocks of P, K, and magnesium (Mg) were not significantly different among the three treatments, whereas Ca stocks were significantly higher in the quarry restoration area (8,998 kg Ca ha-1) than in the adjacent pine (697 kg Ca ha-1) and oak (660 kg Ca ha-1) forests. The results suggest that the quarry restoration area needs to apply organic matter and N fertilizer with amelioration of soil alkalinity.
