- Аннотация: The operation of stationary soil lysimeters is largely determined by the areal and vertical limitationsof the soil mass. The areal spatial limitations of large lysimeters operating at the Moscow State University SoilStation and the proximity of phytocoenoses developing in them to each other contribute to the additionaltransport of plant litterfall by wind, while the vertical limitations eliminate the role of groundwaters and theirsoil-forming effects. The absence of lateral subsurface flow that is typical for natural landscapes and theincreased inflow of alkaline-earth elements with atmospheric precipitation and dust reduce the manifestationof the eluvial–illuvial process. Comparative analysis of lysimetric waters in 1967–1968 and in 2014–2015shows a significant increase in concentrations of such cations as calcium, sodium, magnesium, and potassiumand such anions as chloride and sulfate over this period. The local spatial geochemical contrast of lysimetricwaters caused by the impact of deicing agents does not affect the relative migration capacity of elements.Based on their biogeochemical accumulation levels in the soil, macroelements form the following seriesCa > K > Al > Mg > N; microelements: Zn > Sr > Cu > Ba. The above patterns persist in all types of lysimeters.The calcium concentration in soils increases in the series: broadleaf forest > mixed forest > spruce forest >black fallow. The increased accumulation of elements in soils of spruce forests correlates with the humus type(moder-like) formed under them; this humus type is determined by the combination of coniferous and deciduouslitterfall.
