“…All the pedons were also tentatively classified as mesic. Tanaka et al (1995) had reported a mesic temperature regime for some Andisols located in comparable climatic environments in the Tohoku region. A soil with a mesic temperature regime has a temperature between 8 and IYC at a depth of 50 cm and its mean summer and mean winter temperatures differ by at least 50C (Soil Survey Staff 1997).…”

Andisols of the Kitakami mountain range were derived from a mixture of tephras and long range eolian dust deposited during the Quaternary. Thus, the relative proportions of the components of the mixture determined the unique properties of the soils. Soils of the northern and central parts of the mountain range were derived mainly from tephras and had been classified, generally, as Typic Kuroboku soils by the Group of Japanese Pedologists. Soils of the southern part showed a strong influence of long range eolian dust and had been classified, generally, as Typic Para Kuroboku soils. We studied the Andic soil properties of 35 pedons covering the mountain range in order to classify them under the Andisols order. All the soils showed a bulk density (BD) < 0.90 Mg m-3 and Pretention >85% in the Andisol diagnostic horizon. The soils of the northern and central parts of the mountain range had a pH(H 2 0) range of 5.1-6.7 and acid oxalate-extractable Al plus half Fe (Alo+0.5Feo) level was >2%. They were therefore classified under criterion one of the Andic soils requirements. The soils of the southern part of the mountain range had a pH(H 2 0) range of 4.3-5_7 and the majority of them contained <2.0% of Al o +0.5Fe o . The pedons with Alo +0.5Fe o level < 2.0%, however, had a sufficient amount of volcanic glass in their sand fraction to satisfy the criterion two of the Andic soil requirements. The soils of the northern part contained moderate amounts of organic C and were mainly Typic Hapludands. The soils of the southern part contained large amounts of KCI-extractable Al and organic C and also showed a wider spectrum of Andisols. However, Alic and Typic Fulvudands, and Alic and Typic Melanudands tended to occur in higher frequencies. The classification of the pedons of the central part bridged that of the pedons of the northern and the southern parts.Key Words: Andisols, Kitakami mountain range, long-range eolian dust, tephra, USDA Soil Taxonomy.Soils derived from tephras and others with similar properties, perhaps more than any other group of soils, have been subjected to continuous changes in their terminology. Apart from numerous local names, these soils have been classified variously; Ando soils (Thorp and Smith 1949), Andosols (FAa/UNESCO 1974), Andepts (Soil Survey Staff 1975) and, presently, Andisols (Soil Survey Staff 1990. The extent of the changes is a measure of the advances in the knowledge of their pedogenesis. Although these soils have originally been associated solely with tephra, with the creation of the Andisols order and its subsequent revisions, Andisols derived from parent materials other than tephra have been reported. The reports cover tephric nonallophanic Andisols (Baham and Simonson 1985;Hunter et al. 1987;Shoji and Otowa 1988), nontephric nonallophanic Andisols (Garcfa-Rodeja et al. 1987;Clayden 1989;Leamy et al. 1990;Baumler and Zech 1994) and non-tephric allophanic Andisols (Whitton et al. 1985). Thus, the central concept of Andisols has expanded from soils dominated by allophane, imogolite...

“…This correlation might be induced by hexose originating from microorganisms. According to Tanaka et al (1995), the amount of neutral sugars including mannose considered to be mainly of microbial origin was highly correlated with the total carbon content in volcanic soils in Japan, and the correlation of the content of cellulose-type glucose which was assumed to be mainly of plant origin was relatively less significant. The content of humic acid as well as that of total carbon was significantly correlated with the contents of hexose and pentose in all the fractions, and showed a higher correlation with the pentose content in cellulosic carbohydrates (r = 0.763, p <0.001).…”

At Mt. Hirugatake in the W z a w a Mountains, Kanto district, Japan, the deciduous broadleaved forests have rapidly declined. In our previous studies, we reported that the amount of soil organic matter had significantly decreased at the early and final stages of forest decline, and that the soil microbial biomass also showed a large decrease at these stages, suggesting that the composition of soil organic matter might have also changed with forest decline. To clarify the influences of forest decline on the composition of soil organic matter, the amount of humic substances, optical properties of humic acid, and the amount of soil carbohydrates in surface soils at m e r e n t stages of forest decline were investigated. The amounts of humic acid and fidvic acid decreased to a lesser extent at the early and middle stages of forest decline, and showed a significant decrease at the final stage. As the amount of humin significantly decreased at the early stage, it was plausible that the distinct decrease in the total carbon content of the soil surface horizons at the early stage of forest decline was induced by the decrease in the amount of humin, and at the final stage, by the decrease in the amounts of humic acid and fulvic acid. The amount of soil carbohydrates did not change appreciably with forest decline although the soil organic matter content markedly decreased. It was suggested that most of the carbohydrates in the soil surface horizons were in a stabilized form consisting of complexes with humic substances, metals, and minerals, and would not be affected by the environmental changes associated with forest decline.
