Экологический аспект твердости почвы в пристенной дубраве
Ecological aspect of the soil mechanical resistance in the oak forest of the steep bank

Summary/Abstract: The obtained data revealed that soil mechanical resistance is an important factor affected many essential ecological properties of the biogeocoenosis. The soil layer’s mechanical resistance of 5MP is a limitation factor for the projective cover of herbaceous vegetation. If the 5MP mechanical resistance spreads to upper soil layer up, then the the grass cover decreases. The development of the plants projective cover affects the soil animals’ trophic activity and soil electrical conductivity. The expansion of the plant cover impacts on the capasity of dead plant horizon. The decrease of the projective plant cover favours the increase of the litter mass. The litter also influences the soil animals’ trophic activity and soil electrical conductivity.
