The measurement of pH in the rhizosphere soil was conducted to clarify whether the growth of pokeberry plants affect the acidity of rhizosphere soil in two environmentally contrasting area Ulsan and Chongju city. The rhizosphere pH between 5.25 and 5.33 was shown in the pokeberry stand at Mt. Boomo located at Chongju. The rhizosphere pH of pokeberry stands at Mt. Bongdae, Mt. Sinsun and Mt. Totchil was below 5.0, and did not differ with depth and distance from the main axis of root. At Mt. Bongdae, however, the pH in the rhizosphere soil was significantly changed with soil depths though that was not changed horizontally. The rhizosphere pH at top soil was lower than that at subsoil, which indicates the fact that soil acidification at Mt. Bongdae was not caused by pokeberry plants. Furthermore, the rhizosphere pH did not change with the growth of pokeberry plants. These results indicate that the hypothesis that pokeberry plants acidify local soil environment should be reconsidered.
