    Japanese Black cattle (Japanese Wagyu) beef is attracting attention for its aroma and marbling, and its handling is increasing worldwide. Here, we focused on the origin discrimination of Wagyu beef and analyzed the nutritional components of Japanese Wagyu (produced in multiple prefectures of Japan), Hybrid Wagyu (a cross between Angus and Wagyu cattle born in Australia and transported to Japan), and Australian Wagyu beef using mass spectrometry (MS). Triple-quadrupole liquid chromatography-MS was used to clarify the molecular species of lipids in Wagyu beef. Fourteen classes of lipids were separated, and 128 different triacylglycerides (TGs) were detected. A simple comparative analysis of these TGs using high-performance liquid chromatography revealed significantly higher levels of triolein (C18:1/C18:1/C18:1; abbreviated OOO) and C18:1/C18:1/C16:1 (OOPo) in Japanese Wagyu. Wagyu elements beef were comprehensively analyzed using inductively coupled plasma (ICP)-MS and ICP-optical emission spectrometry. We found significant differences in the rubidium, cesium, and lithium levels of Japanese and Australian Wagyu beef. On comparing metabolites using gas chromatography-MS, we identified significant differences in the levels of amino acids and other components of the Japanese and Australian Wagyu beef. These results suggest the possibility of determining the origin of Wagyu cattle breeds using MS and genetic discrimination.

    In response to decreases in the assimilation efficiency of CO2, plants oxidize the reaction center chlorophyll (P700) of photosystem I (PSI) to suppress reactive oxygen species (ROS) production. In hydro-cultured sunflower leaves experiencing essential mineral deficiencies, we analyzed the following parameters that characterize PSI and PSII: (1) the reduction-oxidation states of P700 [Y(I), Y(NA), and Y(ND)]; (2) the relative electron flux in PSII [Y(II)]; (3) the reduction state of the primary electron acceptor in PSII, QA (1 - qL); and (4) the non-photochemical quenching of chlorophyll fluorescence (NPQ). Deficiency treatments for the minerals N, P, Mn, Mg, S, and Zn decreased Y(II) with an increase in the oxidized P700 [Y(ND)], while deficiencies for the minerals K, Fe, Ca, B, and Mo decreased Y(II) without an increase in Y(ND). During the induction of photosynthesis, the above parameters showed specific responses to each mineral. That is, we could diagnose the mineral deficiency and identify which mineral affected the photosynthesis parameters.

    "Heatphos method" is a technology to recycle phosphorus by adding calcium to heated sewage sludge. In this study, two calcium-rich phosphorus materials air dried or roasted at 700℃ were used as phosphorus fertilizers. These two phosphorus materials were named dried recycled calcium phosphate (dRCP) and roasted recycled calcium phosphate (rRCP), respectively. The monomial efficiencies of dRCP and rRCP were compared with that of single superphosphate (SSP) by the following. 1) The effect of each added phosphorus fertilizer (SSP, dRCP, rRCP) on phosphorus availability on five soil types. 2) The response of three crops [maize (Zea mays L.), soybean (Glycin max L. Merr.), and groundnut (Arachis hypogaea L.)] grown in pots to the three phosphorus fertilizers. 3) Phosphorus adsorptions on the five soil types incubated for six months as evaluated from the three phosphorus fertilizers. Available P measurements show no significant difference among the three fertilizers on Red soil, Gray Lowland soil, Andosol or Non-allophanic Andosol, but the available P of Terrestrial Regosol (pH 8.2) showed that both dRCP and rRCP were inferior to SSP. The effect of dRCP on P uptake by maize was found to be equal to or better than that of SSP in Andosol and Red soil (pH 5.9 and 4.7, respectively) ; however, those of dRCP and especially rRCP were much lower than SSP in the Terrestrial Regosol (pH 8.2). These results indicated that the effect of RCPs may be affected by soil pH. dRCP showed high efficiency in relatively low pH soils ; this result suggests that it is possible to use dRCP as P fertilizer as well as SSP at low pH soil. However, rRCP was less soluble than the other two P sources (SSP and dRCP) because the roasting procedure may develop the crystallinity of calcium phosphate. In Non-allophanic Andosol and Red soil, the influence of incubation on P uptake by crops was different from expectation from P absorption coefficient of soil. It may be necessary to develop a new evaluation method for P adsorption in soil.

    The chemical composition of the hydrophobic acid fraction, which is adsorbed to XAD-8 resin at low pH and desorbed with high pH solution, of water-extractable organic matter in soil probably influences its environmental role and, therefore, it is important to recognize the differences in its chemical composition with season and soil horizon. Hydrophobic acid fractions were collected seasonally in 2004 from Oi, Oe/Oa, A and B horizons of Cambisol and were investigated using elemental analysis, high-performance size exclusion chromatography and ^1H nuclear magnetic resonance (NMR) spectroscopy. Atomic ratios of H/C and O/C decreased with increasing soil depth in winter and summer, suggesting that the hydrophobic acid fraction from lower mineral horizons had lower saturated bond content and carbohydrate content than the fractions from upper organic horizons. Based on high-performance size exclusion chromatography, the molecular weight at peak maximum of the hydrophobic acid fraction decreased significantly with increasing soil depth. The ^1H NMR spectra of the hydrophobic acid fraction showed remarkable changes. The signal intensities of carbohydrate protons (δ 3.0-4.3 p.p.m.) in the hydrophobic acid fraction from organic horizons decreased from winter to summer and increased in autumn, while the signal of aliphatic protons (δ 0-3.0 p.p.m.) increased and decreased. In all seasons of the year, the signal intensities of carbohydrate protons were greater in organic horizons and decreased significantly with depth in mineral soil, but the signal for aliphatic protons increased. Our results demonstrate that season and soil depth influence the chemical composition of the hydrophobic acid fraction of water-extractable organic matter.

    An attempt to create a soil amendment containing Type A humic acid-like substances was done by means of thermal incubation of a mixture of rice straw (RS) and coal fly ash (CFA). The specific objectives of the study are the following: 1) To make an effective use of CFA, a by-product of coal-fired power stations, and 2) To fix carbon in the soil for a long term period as Type A humic acids which are known to be hard to decompose. Optimal incubation conditions to create Type A humic acid-like substances were examined. Furthermore, the chemical properties of the created samples were analyzed. The results obtained can be summarized as follows: 1) It was found that among the three temperature conditions imposed (60, 75 and 90℃), 90℃ was the most suitable for the progress of humification, and that a water supply was very necessary. 2) Since the humic acid-like substances extracted from the incubated sample showed a high degree of humification at the pH range of 3-4, the increase in the degree of humification of the humic acid-like,substances may be accelerated by maintaining a low pH condition during incubation. 3) The highest RF value was observed in the mixture with a dry weight ratio of 1:1 (CFA:RS) after 180 d incubation at 90℃ with water. The 〓logK and RF values of the humic acid-like substances extracted with the mixed solution (pH 7) of 0.1 mol L^<-1> Na_4P_2O_7 and 0.1 mol L^<-1> H_4P_2O_7 was 0.686 and 94.2 respectively, and these humic acid-like substances corresponded to Type A humic acids. 4) The yields of Type A humic acid-like substances from the incubated mixture of CFA and RS (dry weight ratio of 1:1 and 1:2) were estimated to be at least 13.6% and 14.6% of the carbon contents of the samples at the start of the incubation, respectively. 5) The contents of nutrients, such as nitrogen and phosphorus in the incubated sample were smaller than those reported for other soil amendments such as rice straw compost. Therefore, additional application of nitrogen and phosphate fertilizers would be needed in the actual scene for agronomical application of this soil amendment.

  • Humification of three plant residues with Sakurajima volcanic ash as influenced by phosphate addition and low pH condition
    Bulosan-Atendido SA, Suzuki Takeshi, Otsuka H, Fujitake Nobuhide, ISHIBASHI T
    The influence of phosphate addition and low pH condition on humification of three plant residues were determined by performing model thermal incubations of the plant residues rice straw (Oryza sativa), broadleaf sawdust (Kashiwa, Quercus dentate), and coniferous sawdust (Japanese cider, Cryptomeria japonica) with Sakurajima volcanic ash. Four experimental set ups were prepared: (Group 1) plant residues only; (Group 2) plant residues with Sakurajima volcanic ash; (Group 3) plant residues with Sakurajima volcanic ash and Na_2HPO_4; and (Group 4) plant residues with Sakurajima volcanic ash and Na_2HPO_4 with the pH adjusted to 5. Humic acids were extracted using a mixed solution of 0.02 M Na_4P_2O_7 and 0.1 M NaOH. Extractable Fe and Al oxides were determined using three different extraction methods: dithionite-citrate-bicarbonate (DCB), acid-oxalate (TAMM), and Na-pyrophosphate (NaPP). The pH values obtained for Group 1 samples ranged from 2.75 to 6.21; Group 2 samples were from 3.74 to 4.78; Group 3 samples were near neutral or alkaline, ranging from 6.93 to 7.59; and the values for Group 4 samples ranged from 5.38 to 6.28. The ΔlogK values decreased with longer incubation times while the RF values increased. Group 3 samples showed a decrease in RF values compared to Group 2. Type A humic acids were produced only from Group 2 samples derived from rice straw and broad leaf sawdust after about 120 incubation days. The amounts of the Fe and Al from all types of extraction methods decreased in Groups 3 and 4 indicating a possible binding up of these components with phosphate ions. It can be concluded that addition of Na_2HPO_4 increased the pH of the system and at the same time lowers the solubility of Fe and Al present in the Sakurajima volcanic ash. However, adjusting the pH to 5 to maintain lower pH conditions, has slightly increased the solubility of Fe and Al. Therefore, the higher the amount of extractable Fe and Al, the higher the RF values indicating a faster humification process. The relatively small amounts of Fe and Al in higher pH values and their reaction with phosphate rendered these components ineffective in hastening the humification process. Based on the correlation analysis, Al was more effective in hastening the humification process than Fe.

  • Properties of soil humic substances in fractions obtained by sequential extraction with pyrophosphate solutions at different pHs.
    FUJITAKE Nobuhide, STRYNAR M. J, YANAGI Y, SUZUKI T, OTSUKA H
    The FT-IR and ^1H NMR spectra of humic acids, which were obtained from four soils of different types (a Fibric Histosol, Dystric Cambisol, Umbric Andosol, and buried Umbric Andosol) by sequential extraction with pyrophosphate solutions at different pH values (i.e. at pH 3, 5, 7, 9, 11, and 13), were measured. The shape of the IR spectra for each humic acid depended on the differences in the soil origin rather than the pH values. The IR spectra of humic acids in the Histosol and Cambisol showed typical absorption associated with lignin. The humic acids in the Andosol and buried Andosol were characterized by the disappearance of the absorption assigned to aliphatic C-H and the prominence of the absorption attributed to aromatic C=C and COOH groups. The humic acids in the Histosol and Cambisol showed aliphatic properties compared with those in the Andosol and buried Andosol. As the pH values of the extractant increased, the absorption strength of the bands attributed to aliphatic and amide groups increased and those to carboxylic groups decreased. The XH NMR spectra were broadly divided into five regions, namely aromatic (H_), methoxyl (H_), and aliphatic protons a (H_α, β(H_β), and γ(H_γ) to aromatic rings, while the proportion of each proton species was estimated. The proportion of H_ in all the humic acids, except for the humic acids at pH 3 in the Histosol and the Andosol, decreased with the increase of the pH values. The increase of the ratio of H^ to Har with the increase of the pH values, was more conspicuous in the following order: Cambisol > Andosol > Histosol and buried Andosol. Based on the results obtained in this study and the results from repeated analysis of the particle size distribution by gel permeation chromatography conducted in Fujitake et al. (.Soil Sci. Plant Nutr., 44: 253-260, 1998), a model representation of the relationship between the proton composition and particle size in taking account of the differences in the properties of humic acids among soil types and extraction pH values, was illustrated.

    It will be important in future analyses of humic acids (HAs) by various chromatographic and spectrometric methods to obtain high yields of methylated HAs. A derivatization procedure for permethylation of HAs was evaluated in relation to the yield of the chloroform-soluble fraction. The procedure involved a 3 h incubation of HAs (50 mg) with methylsulfinyl carbanion (MSC) obtained by mixing petroleum-purified NaH with anhydrous dimethylsulfoxide (DMSO), followed by incubation with methyl iodide (CH_3I). Ten HAs isolated from different Japanese and American soils (three Andisols, four Inceptisols, one Histosol, one Alfisol, and one Ultisol) were used to optimize this procedure. Optimum derivatization was achieved within the first 6 h after the addition of MSC and CH_3I; further incubation (up to 24 h) did not result in significant changes in the yield of the chloroform-soluble fraction (60-100%). For most HAs, the maximal yields of chloroform-soluble fractions were obtained at concentrations of 10 mM for MSC and 13 mM for CH_3I.

  • Occurrence of Smectite on the Pumice Surface Derived from Taal Volcano in the Phillppines
    SUZUKI Takeshi, OTSUKA Hiroo, BABIERA Victorciti B., BRIONES Angelina M., FUJITAKE Nobuhide, OHTA Takeshi, ATENDIDO Socorro A. B.
    The pumice layer was derived from the northwest fringe of Taal Volcano somma in Kaybagal, Tagaytay City in the Philippines. It has a gravel diameter of 3 to 5 centimeters (cm). The pumice gravel has a yellow surface color and a black inner color. These were observed using an optical microscope and scanning electron microscope (SEM). The chemical and mineralogical constituents were determined using a electron probe micro analyzer (EPMA), and X-ray diffraction apparatus. The results obtained from the optical microscope and SEM showed bubbles in the black or inner part of the pumice, while the surface showed weathered fine particles. Some of the bubbles observed were also partly weathered. The X-ray diffraction pattern showed smectite as the predominant mineral in the yellow surface layer, while amorphous materials were predominate in the black inner part. We speculate that smectite of the pumice may result from the weathering of amorphous glass in the inner part of pumice.

    Humic substances are most predominant organic carbon on the surface layer of the earth, and are distributed ubiquitously on there. The objective of this study was to propose the visual and actual models of humic substances for enlightening their importance. Humic substances were analyzed from point of view of diversity and poly-dispersed properties. Results were described as follow: 1) A number of samples that were generated from various sources materials and/or different environmental condition were obtained, and the database were constructed from analytical data of carefully screened samples (83 from soils, 75 from rivers and lakes, 13 from soil solution, and 11 from manure etc.), by using NMR analysis, elemental analysis and HPSEC analysis. 2) Among soil humic acids from A horizons, their chemical properties differ among soil types. Among rivers and lakes humic substances, their chemical properties differ from colored water to clear water. For water-soluble humic substances in soils, their chemical properties were similar among samples from 0 horizons while were different among samples from A horizons. 3) The grouping model for humic substances was accomplished by the database as described above 1), and visual image of each group of humic substances were proposed on the basis of the grouping model. 4) On the basis of the grouping model for humic substances, typical humic acids from four types were selected and divided to 64 fractions by sequential extraction techniques and preparative HPSEC technique. As a results, the fraction samples reduced the poly-dispersed properties of humic substances were obtained. It was shown by the analytical data that changes of chemical properties with changes of their molecular sizes in each humic acid. 5) After taking every factor into consideration, the visual image comprehended diversity and poly-dispersed properties of humic substances were proposed.

    In a 450-year-old Douglas fir stand, attached dead branch mass was estimated at 2.60 to 5.56 t and occupied ca 1/4 of total live branchwood mass. Live branchwood died attached at a rate of 0.24% yr^<-1>. Due to branchfall and fragmentation 0.37% yr^<-1> and 4.34% yr^<-1> of live- and dead- branch mass were lost respectively. Dead wood mass of 30.88t ha-1 yr-1 was supplied from the canopy to the ground. Live branch size distribution of Japanese broadleaved trees followed power functions with a gradient of ca 2.5, and the size of fallen branches showed the same pattern as well. The ratio of fallen to attached branches was 3 to 10% in number. In a Japanese secondary broadleaved forest under warm temperate climate, aboveground dead woody mass was estimated at 9.3tC ha^<-1>, accounting for 21% of total aboveground mass. A model parameterized by temperature, water content and decay characteristics of dead wood estimated annual respiration of dead woody parts at 0.5tC ha^<-1>. Smaller size root less than 2mm diameter occupying 15% of total root mass contributed more than 60% of total root respiration.The ratio of root to total soil respiration showed large seasonal fluctuation between 18.7% and 59.8%, although its annual mean was 47%. Annual soil respiration was 9 tC in this forest. In the same forest, water-soluble organic matter in soil was retained largely in A horizon. Carbohydrate moiety in the water-soluble humic substances decreased from litter to B horizon. Chemical and structural properties of the water-soluble humic substances changed with soil depth probably due to microbial degradation in litter and to adsorption to mineral soil in mineral horizon. Humic acids accumulated in soil accounted for 15-16% of total soil organic matter and were 7-24 times higher than water-soluble organic matter.

    ニューファンドランド島(カナダ)において、クロトウヒ(Picea mariana)林土壌とその火事跡地(カルミア(Kalmia angustifolia)が優占)、12年、24年、50年、100年経ったヒース土壌の化学性の変化と、植物毒との変化を検討した。化学性としてはpH、EC、BrayNO2法のリン、全炭素、全窒素、アンモニア態窒素、交換性塩基を測定し、植物毒としては単純総フェノールを測定した。 火事後12、24年経ってもクロトウヒ林は再生せずに、ヒースを形成していた。50年後、100年後は、次第に、パッチ上のクロトウヒ、バルサムモミ(Abies balsamea)が存在し、wood-savannaを形成しつつあった。土壌断面は火事後もほとんど変化が認められず、微地形による変動が大きかった。 土壌化学性としては、O層に置いてBray P、pH(H2O)、EC、ExK、ExCa、NH4-Nが時間とともに減少し、CN、TC、ExMgが火事後の時間の経過とともに増加する傾向が認められた。一方総フェノール含量はヒース化により、上昇傾向が認められたが、火事後の経過に伴う増減は認められなかった。以上の結果から、山火事後のヒース化によりO層の土壌肥沃土は減少し、フェノール含量は変化しないことがわかった。 以上の結果から、ヒースを形成するカルミアなどが出す植物毒よりも、土壌肥沃土の減少能力の法が、ヒース形成維持に役立っていると予想された。
