This study was carried out to evaluate the effects of soil conditioner treatments in chestnut cultivated stands in Jinju-city and Sancheong-gun, Gyeongnam province. The chestnet cultivated stands were treated with four fertilization (organic fertilizer 20kg/tree, compound fertilizer 4kg + woody charcoal 2kg/tree, lime fertilizer 3kg/tree, and compound fertilizer 1kg+organic fertilizer 10kg + woody charcoal 1kg/tree) and control treatments. The soil type was reddish brown dry forest soil in Jinju and slightly wet brown forest soil in Sancheong. Soil property in chestnut cultivated stands was changed following soil conditioner treatments. Soil liquid phase in Jinju was increased after soil conditioner treatments, while soil bulk density, solid phase and air phase in Sancheong and Jinju were not changed following soil conditioner treatments. Soil pH following soil conditioner treatments was increased 0.17 - 0.42 units except for compound fertilizer treatment. However, organic carbon and total nitrogen content were not changed following soil conditioner treatments. Calcium and magnesium concentrations following soil conditioner treatments were increased in Jinju, but the concentration was not affected by soil conditioner treatments in Sancheong. The result indicated that the soil property following soil conditioner treatments was more changed in Jinju than in Sancheong.
