abstract:
In model experiment (anaerobiosis) with full saturation of soil samples with water and their incubation at 5, 10 and 20°C during 0-60 days, phosphate ions (PO4–3) 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 PO4–3 concentration in the range of 0.18-2.10 mg dm–3 was found, depending on the temperature and time of soil samples incubation and also on the place of sampling.
