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 pH_KCL 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.

蚁丘对Bryansk Opolie休耕地灰色森林土壤化学性质和放射性核素迁移的影响

富美禾蚁丘，发生在覆盖着灰色淋溶phaeozems，同时改变当地的纹理和土壤性质在布良斯克Opolie休耕土地面积很大的数字。它们的穹顶中的土壤pH _KCL比周围土壤平均高0.6个单位。在最上层的5 cm土层中，记录到有机质含量增加，并且流动性磷和钾含量增加，而阳离子交换容量和水解酸度却降低了。蚁底内外的天然放射性核素分布是均匀的。在蚁丘下更深的深度发现了最大的¹³⁷ Cs技术。可以用蚂蚁的自慰活动来解释。
