Abstract
본 연구는 우리나라 대표적 낙엽활엽수종인 참나무류 중 상수리나무 임분 72개소, 신갈나무 임분 150개소, 졸참나무 임분 97개소, 굴참나무 임분 104개소 등 총 423개소를 대상으로 토양 물리·화학적 특성을 조사하였다. 토양 물리적 특성 중 모래 함량은 상수리나무 임분이 졸참나무, 굴참나무, 신갈나무 임분에 비해 유의적으로 높았으나, 점토 함량은 타 참나무류 임분에 비해 낮게 나타났다. 토양 pH는 임분 간 차이가 뚜렷하여 신갈나무나 졸참나무 임분이 상수리나무나 굴참나무 임분에 비해 토양 산성화가 심하였다. 토양 유기탄소 및 전질소 농도는 신갈나무 임분이 졸참나무, 굴참나무, 상수리나무 임분에 비해 유의적으로 높았다. 유효인산은 신갈나무와 졸참나무 임분이 굴참나무나 상수리나무 임분에 비해 유의적으로 높았으나, 교환성 포타슘, 칼슘, 마그네슘 농도는 낮게 나타났다. 양이온교환용량은 신갈나무, 졸참나무, 굴참나무, 상수리나무 임분 순이었다. 국내 참나무류 임분의 토양 물리·화학적 특성은 임분 간 차이가 있었으며, 신갈나무와 졸참나무 임분은 낮은 토양 pH와 교환성 양이온 농도를 개선할 수 있는 양분관리 방안을 모색할 필요가 있다.
This study was conducted to compare the physical and chemical properties of soils in Quercus acutissima, Q. mongolica, Q. serrata, and Q. variabilis stands. A total of 423 plots (Q. acutissima 72 plots, Q. mongolica 150 plots, Q. serrata 97 plots, and Q. variabilis: 104 plots) were examined to determine the soil properties of A and B horizons throughout the country. The physical and chemical properties of soils were significantly different among the four different Quercus spp. stands. The sand content in both horizons was significantly higher in Q. acutissima stands than in the other three oak stands, whereas the clay content was lowest among the four stands. The soils in Q. mongolica and Q. serrata stands were more acidified than those in Q. acutissima and Q. variabilis stands. The concentrations of organic carbon and total nitrogen in both soil depths were significantly higher in Q. mongolica stands than in Q. serrata, Q. variabilis, and Q. acutissima stands. The content of available phosphorus was significantly higher in Q. mongolica and Q. serrata stands than in Q. acutissima and Q. variabilis stands; whereas the contents of exchangeable potassium, calcium, and magnesium were lower in Q. mongolica and Q. serrata stands than in Q. acutissima and Q. variabilis stands. The cation exchange capacity was highest in Q. mongolica stands, followed by that in Q. serrata, Q. variabilis, and Q. acutissima stands. These data indicate the need to design a nutrient management plan to enhance the low soil pH and exchangeable cation in Q. mongolica and Q. serrata stands.
