ABSTRACT:
In the years 2008-2011, the study of surface and subsurface water runoff from the forested loess slope was carried out to determine the concentrations of selected chemical indicators of water quality, soil suspension and loss of the pure matter component. Maximum concentrations of water quality indicators tested were low and amounted to: 1.841 mg‧dm-3 N-Nog, 0.943 mg‧dm-3 N-NH4, 0.478 mg‧dm-3 N-NO3, 0.213 mg‧dm-3 N-NO2, 0.423 mg‧dm-3 P, 1.621 mg‧dm-3 K. The masses of the eroded matter constituents were low and amounted to: 0.808 kg‧ha-1 N, 0.157 kg‧ha-1 P, 0.142 kg‧ha-1 K and 2.989 kg‧ha-1 soil. Parameters of erosive precipitation and water outflow were statistically significantly correlated with the concentration of soil suspended matter and losses of the analyzed components of matter, and negligible concentration of chemical indicators of water quality. Afforestation of loess slopes threatened by erosion is a treatment that effectively protects the soil against water erosion.
