Abstract

Distributions of weakly acidic and strongly acidic soils in non-Andosols of Japan was shown using the data of exchange acidity y_1, which appeared in the soil survey reports on reclaimed land. The soils having less than 15 gP_2O_5 kg^<-1> of phosphate absorption coefficient were regarded as non-Andosols from the data of Hikazanseido, and soil profiles of 2876 non-Andosols were divided into two groups by exchange acidity y_1: exchange acidity y_1 < 6 for weakly acidic soil and exchange acidity y_1 ≧ 6 for strongly acidic soil. The weakly acidic soil occupied 24% of the total soil profiles and scattered in Japan. On the other hand, the strongly acidic soil occupied 76% of the total soil profiles and distributed in northern part of Hokkaido District, central part of Tohoku District, a part of Hokuriku District, a part of Chubu District, a part of Kinki District, Chugoku District, Shikoku District, and northern part of Kyushu District. These results suggested that the distribution of strongly acidic non-Andosols roughly corresponds to the distribution of non-allophanic Andosols.
