Abstract
This study was carried out to examine the effect of soil improvement according to the shape of charcoal and the kind of carbonized tree species. As the results, all of the seedlings of Thuja occidentalis and Aesculus turbinata grew better in the charcoal-treated soil than the non-treated soil. In case of powder charcoal, Thuja occidentalis seedlings grew up best in the soil treated with powder charcoal of Pinus koraiensis and then grew well in order of Larix leptolepis > particle board > Quercus acutissima. In case of granulated charcoal, the seedlings grew well in order of the granulated charcoal of Larix leptolepis > particle board > Pinus koraiensis. It was analyzed that the soil porosity and the organic matter content were mo re in the charcoal -treated soil than the non-treated soil also. It is inferred that because the aeration property and the absorption of organic matter were increased in the root zone, the growth of seedlings was better in the char-coal-treated soil.
