Description
We analyzed the top 15 cm of soil at 133 sites in a region of Andosols around the northern Aso somma and the east of the Kuju Plateau, Kyushu; we divided the samples into 69 nonallophanic soils (Al_p/Al_o ≥ 0.5), 59 allophanic soils (Al_p/Al_o < 0.5), and 5 non-Andosols. Nonallophanic soils were densely distributed on the Kuju Plateau and on the northwestern Aso somma; their acidity was similar to that of nonallophanic Andosols in other regions, such as Tohoku, whereas the total carbon content, the ratio of total carbon to Al_p/Al_o, and the ratio of total carbon to Al_p were larger than those of other regions. In addition, the relatively large Sio of the nonallophanic soils suggested a greater content of allophane and imogolite than in nonallophanic Andosols in other regions. The nonallophanic and allophanic soils in this area could be distinguished to a large extent by pH(H_2O) and color.
