Abstract
This study was conducted in the Chusan Area of Seoul National University Research Forests at Kwangyang, Korea. The objectives were to compare tree growth, soil nutrient distribution and soil profiles at Pinus rigida, Pinus rigida x P. taeda, Pinus taeda and Abies firma stands. Soils were collected from each layer. The amounts of total nitrogen, available phosphorous and potassium,
and soil conductivity and pH were measured. The results obtained from this study were as follows:
I. The amount of total nitrogen, available phosphorous and potassium decreased from A to B layer.
2. All soils are acidic, and soil pH increased from A to B layer.
3. The annual diameter growth rate of Pinus taeda was higher than those of other species.
4. The annual volume growth rate of Pinus rigida x P. taeda stand was higher than those of other species.
