This study was to set the guidelines of soil chemical components in order to assure the safety and quality ofthe panax ginseng from physiological disorder. The disorder symptoms appeared on the leaf with yellow spot, atrophy, yel-low-brown spot, also showed red skin and rough skin of the root. Occurrence type of physiological disorder in cultivatedfield divided into two types:type I ‘such as, yellow spot’ consist of single disorder symptom; type II ‘such as, yellow spotand yellow-brown spot’ consist of two or more different disorder symptoms. The individual contribution of soil properties tothe occurrence type was as follows ; The yellow spot was affected by Na>NO3-N>salinity (EC) in soil. The same results wasobserved in red skin. Atrophy was affected by NO3-N>salinity (EC)>Ca>Mg. Rough skin was affected by P2O5>pH>Organic material > K. It showed positive associated to P2O5, pH and K, but negative associated to organic matter. Simulta-neous occurrence of two different disorder, including cases which yellow spot and yellow-brown spot, those were affected byNO3-N > salinity (EC) > Na > Mg. In the case of atrophy plus yellow-brown spot, those also were affected by in the order :NO3-N > salinity (EC) > Ca > Mg > Na. Red-rough skin was affected in the order : salinity (EC) > NO3-N > K > Na. Soilchemical 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 criticalroles in attributing to complex occurrence of physiological disorder.
