• 論文の詳細を見る

• The potential sulfate acidity of two mangrove soils (Agortoe and Ada) from Ghanaian saline and brackish tidal flats was studied. Potential sulfate acidity was high in both the lower and upper layers of the Agortoe soil which was covered with a thick mangrove vegetation (Avicennia mitida). In the Ada soil which was covered with dispersed mangrove vegetation, potential sulfate acidity was only found in the lower layer. Only the number of sulfur bacteria in the lower layer sample of the Agortoe soil showed a clear decreasing trend with the decrease of the pH. Except for the upper layer of the Ada soil, all the other samples contained pyrite. Based on the results of this experiment it was suggested that pyrite accumulation in the upper layer of mangrove swamp soils is directly related to the thickness of the mangrove vegetation.
