摘要：Erosion strongly influences soil properties and affects the intra-field variation of nutrients not only in steep young morainic landscapes but also on gentle slopes of old-glacial landscapes.The aim of the study was the evaluation of changes in plant-available nutrient contents in the complex old-glacial eroded landscape of the Bielska Plain in the north-eastern part of Poland.The soil samples were collected from soil profiles located along the transect beginning on the flat summit of the kame hummock extending through south-facing convex slope, the toeslope and footslope and further through the north-facing uniform slope.The content of plant-available forms of phosphorus (Pdl) and potassium (Kdl) and mineral forms of nitrogen (NH4-N and NO3-N) were determined in every soil profile.Soils located in various landscape positions were characterized with different fertility.In soil located on the toeslope the content of NO3-N, Pdl and Kdl was high, while soil located on the summit was rich in NH4-N and poor in plant-available forms of K and P.The erosional distribution of plant-available N, P and K enhances the variation of nutrient content within one field and contributes to high variability of crops.
