Effect of Soil Agricultural Use on Particle-Size Distribution in Young Glacial Landscape Slopes

In the literature, mainly particle-size distribution (PSD) analyses in soil catenas, of e.g., moraine and riverine landscapes were discussed. Analysis comparison PSD (ML) ice-dammed lakes (ID-LL) not studied. Since landscape origin has diversified relief is under intensive agricultural use, aspects erosion are great importance. The changes studied 14 catenas (toposequences) eroding soils at upper slope (US) as well colluvial middle (MS) lower (LS) slopes depressions (D). fine fractions (<2 mm) was analysed according to hydrometer method. order describe effect use on variability surface horizons, sedimentological granulometric indices calculated. landscape, content coarse silt fraction increasing catenal sequence from 9.7% US 17.7% D. Similar relationships revealed for content. Significant differences found between average contents LS However, such a relation catena lake landscape. Eroded materials very poorly sorted with standard deviation index 2.65–3.69. Humus horizons had fine, skewed PSD, mesokurtic platykurtic (ML), symmetrical, (I-DLL). cluster analysis enabled separation two groups soils: one group other similar only among within type
