This study was to set the guidelines of soil chemical components in order to assure the safety and quality of the panax ginseng from physiological disorder. The disorder symptoms appeared on the leaf with yellow spot, atrophy, yellow-brown spot, also showed red skin and rough skin of the root. Occurrence type of physiological disorder in cultivated field divided into two types : type Ⅰ 'such as, yellow spot' consist of single disorder symptom; type Ⅱ 'such as, yellow spot and yellow-brown spot' consist of two or more different disorder symptoms. The individual contribution of soil properties to the occurrence type was as follows ; The yellow spot was affected by Na greater than NO₃-N greater than salinity (EC) in soil. The same results was observed in red skin. Atrophy was affected by NO₃-N greater than salinity (EC) greater than Ca greater than Mg. Rough skin was affected by P₂O∧5greater thanpHgreater than Organic material greater than K. It showed positive associated to P₂O∧5, pH and K, but negative associated to organic matter. Simultaneous occurrence of two different disorder, including cases which yellow spot and yellow-brown spot, those were affected by NO₃-N greater than salinity (EC) greater than Na greater than Mg. In the case of atrophy plus yellow-brown spot, those also were affected by in the order : NO₃-N greater than salinity (EC) greater than Ca greater than Mg greater than Na. Red-rough skin was affected in the order : salinity (EC) greater than NO₃-N greater than K greater than Na. Soil chemical components appear to be related to occurrence of physiological disorder, particularly in salinity (EC) and NO₃-N. The salinity (EC) and NO₃-N were negative related to plant growth. In addition, exchangeable cation capacity play critical roles in attributing to complex occurrence of physiological disorder.
