Abstract


The function of the elements of the agricultural landscape: two shelterbelts of different age and the composition of plants, and peatland for the control of the spread of nonpoint pollution in ground water between ecosystems were evaluated. In ground water under shelterbelts and adjoining cultivated fields, and peatland - pH, content of total nitrogen (Ntotal), nitrates (N-NO3 -), ammonium ions (N-NH4+ ) and organic nitrogen (Norganic) were determined. The most significant removing of nitrogen compounds revealed peatland. Two shelterbelts of different age and composition of plants showed lower effectiveness than peatland in concentrations of these compounds in ground water. Moreover, both shelterbelts supplied ammonium to ground water. The manipulation of the rural countryside through the introduction of the shelterbelts and peatlands of different age and the composition of plants, leads to modification of biochemical soil condition and finally efficiency decrease of the nonpoint pollution content in ground water. Thus, we recommend the utilization of young shelterbelt and peatland as favorable element of the landscape for the control of the spread of nonpoint pollution between ecosystems in ground water.
