Zusammenfassung:	To provide a method capable of neutralizing alkaline ground even in various conditions.SOLUTION: As a neutralization method for alkaline ground, an acidic inorganic material and a microorganism activation agent are injected into the ground, or are mixed into soil constituting the ground. In the neutralization method, the acidic inorganic material neutralizes an alkaline component in the ground in a short term so as to reduce a pH of the ground. When the pH of the ground is reduced, native heterotrophy bacteria becomes activated, then metabolizes the microorganism activation agent and decomposes the same into organic acid and carbon dioxide. Since organic acid and carbon dioxide are acidic, they can neutralize the alkaline component in the ground for a long term.SELECTED DRAWING: None 【課題】様々な条件下でもアルカリ性の地盤を中和することが可能な方法を提供する。【解決手段】アルカリ性の地盤の中和方法として、酸性の無機資材と微生物活性剤とを、地盤に注入する、又は、地盤を構成する土壌へ混合する。この中和方法では、酸性の無機資材が短期的に地盤中のアルカリ成分を中和して地盤のｐＨを低下させる。地盤のｐＨが低下すると、土着の従属栄養細菌が活性化し始め、微生物活性剤を代謝してこれを有機酸や二酸化炭素へと分解する。有機酸や二酸化炭素は酸性であるので、これらによって長期的に地盤中のアルカリ成分が中和される。【選択図】なし
