Abstract
The shallow soil depth and severe rock exposures on the hillslopes in the Kwanak aboretum area
which resulted from the heavy soil erosion have made very poor growth of forest vegetation.
In order to establish the forest vegetation in this area, it is urgent to recover the fertility of soil
and the productivity of existing trees.
For this reason, fertilization experiment (using the briquet compound fertilizer) was conducted
on summer and autumn season in 1983 with the 4 main native species (Pinus densiflora, Pinus
rigida, Juniperus rigida, Rhododendron schlippenbachii) growing on these eroded hillslopes. Result
in 1985 and 1986 of this experiment represented that the fertilization was effective toward both
height and root-collar diameter growth of trees and spring fertilization was, relatively, more effective
than autumn fertilization. It also represented that effects of fertilization to P. rigida were more
than those to other species.
Therefore, besides the engineering methods and afforestation measures for soil erosion control,
rapid establishment of vegetation through conservation and recovery of existing trees by fertilization
is available measures for the rehabilitation of rockily eroded hillslopes like Mt. Kwanak area.
