The management of soil chemical properties is very important to sustainable agriculture of many horticultural crops, including cucumber. This study was conducted to find the optimal soil properties of environmentally friendly agriculture in controlled horticulture. Soil chemical properties of 267 samples were collected from soil in Chungnam Province. The average of pH, EC, OM, available P₂O?, exchangeable K, Ca, and Mg was 6.1, 5.38 dS m<SUP>-1</SUP>, 34 g kg<SUP>-1</SUP>, 1,321 mg kg<SUP>-1</SUP>, 1.50 cmolc kg<SUP>-1</SUP>, 10.3 cmolc kg<SUP>-1</SUP>, and 3.4 cmolc kg<SUP>-1</SUP>, respectively. The organic matter content in silty clay loam was significantly higher than in the other soil textures, whereas the pH, EC, exchangeable K, and Mg in loamy fine sand showed significantly lower among soil textures. The EC value and exchangeable Mg concentration were highest in mountain foot-slope soils. The frequency distribution within optimum range of soil chemical properties was 26.2%, 30.3%, 2.3%, 3.8%, 3.4%, and 6.7% for pH, OM, available P₂O?, exchangeable K, Ca, and Mg, respectively. Especially, excessive portion of available P₂O? and exchangeable Ca were 94.0% and 94.4%, respectively. The EC value and organic matter content of soil samples were positive correlation with all chemical properties except soil pH. In principle component analysis of chemical properties in soil samples, the percentage of variance explained by PC 1 was 52.2%, while PC 2 explained 21.3% of the variance, for a cumulative total of 73.5%. In conclusion, these results are considered to improve soil nutrient management for sustainable controlled horticulture.
