内容 We have conducted a series of experiments to obtain fundamental data for the improvement of hedoro soil which are widely existing in lowlands of Japan. In this paper, we investigated the physical and chemical properties of hedoro soils taken from three different place, which were Kasumigaura, Saga and Obagawa hedoro soil existing under the fresh water. We also investigated the changes of pH, carbon content and its effect on the consistency limits and sedimentation volume of hedoro soils by H_2O_2 treatment. When 100ml of 6% H_2O_2 was treated on 10g of soil, the pH of Kasumigaura hedoro soil lowered from 6.5 to 2.9, and Obagawa hedoro soil from 7.6 to 2.4. Also the pH of Saga hedoro soil lowered from 6.8 to 2.2 by 6% H_2O_2 treatment on 50ml. These pHs recovered when treated with an increased amount of H_2O_2. Kasumigaura and Saga hedoro soils changed in the sedimentation volume by air-drying. Kasumigaura and Saga hedoro soils greatly changed in the consistency limits by air-drying, but showed only a little effect of that after the H_2O_2 treatment.
