| Popis: | Formica pratensis anthills, which occur in great numbers in the Bryansk Opolie fallow land areas covered with the grey-luvic phaeozems, change both the local microrelief and the soil properties. The soil pHKCL in their dome is higher than that in the surrounding soils by an average of 0.6 units. In the top 5-cm soil layer, increased contents of the organic matter and the mobile phosphorus and potassium are recorded, while the cation exchange capacity and the hydrolytic acidity are decreased. The natural radionuclide distribution under and outside the anthill is uniform. The technogenic 137Cs in its maximum is found at a greater depth under the anthill. It may be explained by the ant pedoturbation activities. |
