streszczenie
In a model experiment (anaerobiosis) with full saturation of soil samples with water and their incubation at 5, 10 and 20°C during 0-60 days, nitrates(V) concentration in soil solution, Eh and pH in soil sediment were determined. For the investigations 12 samples from loess soils representing surface-humus horizons were taken from various parts of 4 eroded slopes in a small river catchment near Lublin, Poland. Differentiation in nitrates concentrations in the range of 0-1.563 mg dm-3 was found, depending on the temperature and time of soil sample incubation, and also on the place of sampling along the catchment and on the slope.
