This study is conducted to investigate soil chemical properties based on planting structure in thirty urban parks in Daejeon Metropolitan City, Korea. Planting structure in urban parks is categorized into multi-layer planting, single-layer planting (Pines densiflora S. et Z. and P. strovus L.), and the grass. Soil analyses in multi-layer planting have shown that the average pH (1:5, w/w), O.M, P2O5 (mg/kg), CEC (cmol+/kg), T-N, K+ (cmol+/kg), Ca2+ (cmol+/kg), and Mg2+ (cmol+/kg) are 6.88, 0.99%, 52.10, 5.73, 0.05%, 0.15, 5.23, and 0.47, respectively. As a result of soil analyses in single-layer planting (P. densiflora S. et Z.), the average pH, O.M, P2O5, CEC, T-N, K+, Ca2+, and Mg2+ are 6.98, 1.19, 39.14, 5.85, 0.05%, 0.14, 5.47, and 0.74, respectively. Soil analyses in single-layer planting (P. strovus L.) have shown that the average pH, O.M, P2O5, CEC, T-N, K+, Ca2+, and Mg2+ are 5.8, 1.25, 12.75, 5.98, 0.06%, 0.14, 4.66, and 0.46, respectively. In a result of soil analyses in the grass, the average pH, O.M, P2O5, CEC, T-N, K+, Ca2+, and Mg2+ are 7.05, 1.05, 36.54, 6.16, 0.04%, 0.14, 4.78, and 0.56, respectively. In the grass, pH and CEC levels are higher, but T-N level is lower. In multi-layer planting, K+, Ca2+, and P2O5 levels are higher, but Mg2+ and O.M levels are lower. In single-layer planting, however, Mg2+, O.M, and T-N levels are higher, but pH, P2O5, and K+ levels are lower.
