内容記述タイプ Abstract
内容記述 From tephra, not only Andisols, but Spodosols can also be formed depending on changes in the soil formation factors. In Andisols, the in situ accumulation of humus in the A horizon and that of the active Al and Fe in the A and Bw horizons are the major soil formation processes, whereas in Spodosols, the eluviation and illuviation of organic matter (OM), Al and Fe are predominant. Among the soil characterization data, the pyrophosphate-extractable Al (Al_p), cation exchange capacity (CEC) and organic carbon (OC) content were selected in order to examine the similarities and differences in metal complexation and related properties of these soils. The A horizon soils of the Andisols and the Bh-Bhs and Bs horizon soils of the Spodosols derived from tephra (SPT) and those derived from nontephra deposits (SPN) are similar in their Al_p/OC ratios suggesting that the metal complexation of humus is a property common to these horizons. In contrast, the Al_p/OC ratio of the E horizon soils in the SPT and SPN was significantly lower than those in the Bh-Bhs and Bs horizon soils of the SPT and SPN and the A and Bw horizon soils of the Andisols. Furthermore, the CEC in these E horizon soils did not exceed those in the other horizon soils. These results indicate that the static OM in the E horizons has less total carboxyl groups, including both the complexed and free ones, than that in the other horizons. Recent information on the SPN formation was applicable to the SPT according to their soil characterization data.
