Soil environmental factors, affecting population of Fusarium spp. and root rot of Panax ginseng were investigated in the ginseng cultivated soil. In the 2-year-old ginseng cultivated soil, the number of Fusarium spp. and the amount of available phosphorus were significantly decreased as clay content was increased in the soil. Also the missing rate of ginseng plants and the amount of nitrate nitrogen appears to be decreased as clay content was increased in the soil, although, it was not statistically significant. In the 6-year-old ginseng cultivated soil, there was highly significant negative correlation(r=-0.3976, p=0.01) between the number of Fusarium spp. and that of Streptomyces spp. Relationship between root rot and the amount of available phosphorus was significantly positive (r=0.3162, p=0.05), however, there was no correlation between the two factors within same soil torture.
