The local government planned to restore the cracked paddy fields but was aware that acid sulfate conditions（soils with  pH（H2O2）<3.0 and sulfate ions in H2O2-treated soil extract）occurred in the lower soil layers in some parts of the Aso valley. Acid sulfate soils release sulfate ions that form sulfuric acid when the soils are subjected to aeration and oxidation, so it was important that acid sulfate soil layers not be exposed during the restoration process. Therefore, the distribution of acid sulfate soils in Restoration Areas 1 and 2（five fields per restoration area）was mapped, and the chemical and visible characteristics of the soils were determined for information and guidance in the restoration process.\nIn Restoration Area 1, acid sulfate soils existed in shallow soil layers and were highly acidic\n（pH（H2O2）<  1）. In Restoration Area 2, acid sulfate soils existed only at depths below 80  cm and were weakly acidic（pH（H2O2）~3）. The pH（H2O2）values of the acid sulfate soil samples measured one week after sampling were highly correlated with the pH（H2O）of the same soils after being air-dried for approximately three months, confirming that pH（H2O2）of fresh samples is useful for assessing the status of acid sulfate soil. The acid sulfate soils were olive black to black in color, emitted hydrogen sulfide smell and contained discernible partly decomposed plant materials with a peat-like appearance. The information obtained was used by the local government office of Kumamoto prefecture as a guide in the restoration of the paddy fields affected by the earthquake\n","subitem_description_type":"Abstract"},{"subitem_description":"平成 28 年熊本地震では阿蘇谷（阿蘇カルデラ内の阿蘇中央火口丘より北側の地域）においても農地に亀裂や段差が発生し，修復工事が計画された。しかし阿蘇谷の一部の土壌の下層には，黒泥状を呈し，空気に触れて酸化すると硫酸イオンを生成し，強酸性を示すパイライト（FeS2）に富む土層（以後，「酸性硫酸塩土壌」と呼ぶ）が分布することが報告されている（川崎 ,1982）。そこで，修復工事が予定されている阿蘇市内の 2 工区について各 5 圃場で土壌を採取し，酸性硫酸塩土壌の判定のため，過酸化水素処理した土壌の pH（pH（H2O2））を測定した。\n工区1 では pH（H2O2）が 1.0 を下回る強い酸性を示す土層が存在し，作土付近にも出現したが，工区2 では pH（H2O2）が 3.0 程度の土層のみで比較的酸性は弱く，出現する深さも 80\n㎝以深と作土付近での出現は確認できなかった。酸性硫酸塩土壌の土色は緑色を帯びた黒色が多く，酸性硫酸塩土壌と判定された土壌のほとんどで泥炭物質（ヨシなどの植物遺体）が確認された。また，pH（H2O2）が 2 を下回る土層では刺激臭（腐卵臭）が確認できた。現場においても，土色，泥炭物質の有無，臭いで酸性硫酸塩土壌を簡易的に判定できる可能性が示された。以上の結果については，農地の修復工事を担当する熊本県阿蘇地域振興局に報告した。また，酸性硫酸塩土壌の中和石灰量は，上記の pH（H2O2）測定に用いた土壌抽出液中のイオウ（S）濃度（H₂O₂ 処理 S 濃度）から推定可能であった。pH（H2O2）0.87 ～ 2.56 の場合，中和石灰量は乾土重量に対して 5% ～ 30% となり，修復工事により酸性硫酸塩土壌が大量に土壌表面に露出する可能性は低いと考えられるものの，莫大な量となった。","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00002291","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立研究開発法人
