Distribution of elements in soils of moraine landscape in Masurian Lakeland
Wydanie: 1 / 2010
The research was carried out in three catenas, in which the soils made a typical toposequence of the moraine landscape in Masurian Lakeland, i.e. eroded soils, deluvial soils, mucky soils as well as slightly and strongly silted peat-muck soils. The total content of Ca, Mg, K, P, Na, Fe, Mn, Zn and Cu was analyzed in these soils. The amounts of soil organic matter and measured elements showed catenal variation. Mucky soils had the highest content of Mg, K, Fe and Na whereas strongly and slightly silted peat-muck soils contained the highest amounts of P, Mn, Ca and Cu. The content of Ca was positively correlated with organic matter content. The amount of Mg, K, Cu and Mn was positively correlated with the amount of clay fraction. As the studied soils are located at the bottom of a slope, downwards water flow, where mineral compounds are accumulated in deposits or dissolvedin water, mucky soils and silted peat-muck soils contain high amounts of the analyzed elements. Mucky soils and silted peat-muck soils play a role of biogeochemical barriers protecting wetlands against nutrients from surrounding moraine uplands. Surface horizons of deluvial soils were depleted of the analyzed elements (excluding P) whereas AO horizons of mucky soils and Mt horizons of peat-muck soils were abundant in the measured elements (excluding Ca). Various amounts of the analyzed elements in the pedons of the catena sequences should be taken into consideration when planning land use in the moraine landscape, which has unique natural values.
