摘要
The behavior of different elements in solutions from gleyic peaty-podzolic soils was described by four types of fluctuations (from weak to strong ones). With account for the spatial and temporal variation, chemical elements were divided into groups with stable (Si, Al, Na, and Cwso) and variable (Co, Mo, Ni, Sb, and Pb) concentration levels. The spatial variation component of the solution composition was lower than its time dynamics. The intratype variability of the composition of the solutions was insignificant within a season, but it was significantly affected by the contrasting climatic conditions of different years. The solutions from the upper soil horizons had different specific features. The F, H, and AE horizons were similar in their solution composition, and the solutions from the E horizon and litter differed in the concentrations of most macro-and microelements and their pH values.
