“…The predominant soil group is brown forest soil, which covers 70% of the forest sector and has a carbon stock of 87 Mg C ha −1 (Table 5). Japanese brown forest soils are often strongly influenced by volcanic ash (Imaya et al. 2007) and are classified as Andisols in some cases (Soil Survey Staff 2006), but the mean value of all soil groups (90 Mg C ha −1 ) is not as high as we expected and is similar to the value (88 Mg C ha −1 ) indicated in the IPCC guidelines (IPCC 2006).…”

Estimation of carbon sequestration in the forest sector should take into consideration changes in carbon stock in all carbon pools, including above‐ground and below‐ground biomass, litter, deadwood and soil. In this review, we discuss current knowledge of carbon stocks in litter, deadwood and soil in Japan’s forest sector. According to data from published reports and nationwide surveys, the carbon stock in forest litter is less than that indicated in the Intergovernmental Panel on Climate Change (IPCC) guidelines for temperate and cool temperate forests; for example, coniferous species showed 4.4 Mg C ha−1 for Cryptomeria japonica and 3.1 Mg C ha−1 for Chamaecyparis obtusa, and broad‐leaved species ranged from 3.5 Mg C ha−1 for Castanopsis spp. to 7.3 Mg C ha−1 for Fagus spp. For deadwood carbon stock, coniferous plantations with a record of non‐commercial thinning showed 17.1 Mg C ha−1 and semi‐natural broad‐leaved forests showed 5.3 Mg C ha−1 on average, although only limited data were available. The black soil group (comparable to Andosols and Andisols) showed large carbon stocks in soil layers 0–30 cm deep (130 Mg C ha−1). The brown forest soil group (Cambisols and Inceptisols), occupying the most dominant area, showed a carbon stock of 87.0 Mg C ha−1 on average, which was similar to the data shown in the IPCC guidelines. In a comparison of land use between the forest sector and the agricultural sector for the same soil group, the carbon stock in the agricultural soil was 21% lower and in the grassland soil it was 18% higher than the stock in the forest soil. In this review, we also discuss issues for improving the estimation method and inventory of carbon stock in litter, deadwood and soil in Japan.

“…The concentrations of Al and Fe extracted by KCl showed quite low values. The data obtained by a citrate dithionite solution, which can estimate nearly all secondary oxides and organic complexes in soils, also showed low values of Al and Fe as compared with data for various types of soil in central Japan (2.7-28.9 g kg -1 for Al, and 8.1-46.4 g kg -1 for Fe, respectively) (Imaya et al 2007). Consequently, the soil at Mt.…”

“…Volcanic ash soil contains large amounts of aluminum (Al) and iron (Fe) (Bautista and Inoue 1993;Imaya et al 2007; Kayama et al 2011). When plants absorb Al, the cell division of roots and the uptake of various nutrients are inhibited (Marschner 1995;Kochian et al 2004;Yang et al 2011).…”

Key message The growth of Japanese larch seedlings is regulated by the presence of nutrients as well as ectomycorrhizal symbiosis. Abstract The mountain slope of an active volcano is a severe environment for the regeneration of larch (Larix kaempferi Sarg. hereafter larch) seedlings. To determine parameters affecting the growth of larch seedlings, we analyzed stoichiometry of elements in the soils and plant organs, ectomycorrhizal (ECM) colonization, and photosynthetic abilities. These parameters were compared with two different elevations. From nutrient analysis of plant organs from larch seedlings grown on the slope of a volcano, potassium (K) was insufficient compared with the seedlings grown in other habitats. Symbiosis with ECM fungi enabled the uptake of nutrients, especially phosphorous (P) and nitrogen (N). The main factor affecting the differences in relative height growth rate (RHGr) of larch was attributed to ECM colonization. There was a positive relationship between ECM colonization and concentrations of P or N in needles. Larch seedlings with high rates of ECM colonization showed high concentrations of P and N, and had high photosynthetic rates. At lower elevation sites, concentrations of N and K in needles were low with high density of individuals. Moreover, larch showed a high accumulation of aluminum (Al) and iron (Fe) even though the amount of these elements in the soil was small. These seedlings exhibited a suppressed photosynthetic rate and RHGr. Symbiosis with ECM fungi could suppress the excessive uptake of Al and Fe.

“…For example, Takahashi et al (2001) showed that non-allophanic Andosols in several forest soils of Aomori and Akita Prefectures were formed in Pleiocene sedimentary rocks and Miocene green tuff mixed by landslides with no evidence of tephra deposition. Recent studies in forested areas in Japan indicate widespread distribution of non-allophanic Andosols mixed with Brown forest soils (Imaya et al, 2005(Imaya et al, , 2007(Imaya et al, , 2010a.…”

Nature, properties and function of aluminum–humus complexes in volcanic soils

Andosols (or Andisols) possess several distinctive properties that are rarely found in other groups of soils. These properties are largely due to the dominance of short-range-ordered minerals (allophane, imogolite and ferrihydrite) and/or metal-humus complexes (Al/Fe-humus complexes) in their colloidal fraction. While several papers have extensively reviewed the nature and properties of short-range-ordered minerals, there is no comprehensive review of the genesis, characteristics and management implications of Al-humus complexes, the dominant form of active Al in non-allophanic Andosols. In this review, we survey the chemical characteristics of Al-humus complexes and discuss the pedogenic environment favoring their formation in non-allophanic Andosols. The role of Al-humus complexes in carbon cycling and soil organic carbon accumulation is emphasized as an important mechanism controlling organic dynamics in Andosols. While non-allophanic Andosols share many common properties with allophanic Andosols, they display several distinct characteristics associated with Al-humus complexes, such as strong acidity and high exchangeable Al content that impair agricultural productivity due to Al phytotoxicity. Thus, we focus on the role of Al-humus complexes in regulating aqueous Al 3+ solubility and release/retention kinetics, Al phytotoxicity, phosphorus dynamics, and suppression of soil-borne diseases. Knowledge of these soil properties as related to Al-humus complexes is necessary to develop effective soil management practices to assure sustainable agricultural productivity in non-allophanic Andosols. Finally, future research needs are identified concerning the role of Al-humus complexes in regulating soil biogeochemical processes.
