The current study presented a genesis characterisation of iron-illuvial podzols formed on esker mainly coarse-grained deposits consisting of coarse and moderately coarse-grained sands including the gravel-pebble fractions with rubblestones. Under similar bio-climatic conditions, the iron-illuvial podzols on esker showed quantitative differences in composition and their properties from the iron-illuvial podzols formed on sandy moraines. The source of these differences were the relief and lithology of deposit genesis of uncommon structure of esker. The still commonly used description of fluvioglacial deposits, without their differentiation in esker as an inner-glacial deposit and periglacial deposits formed out of glacier range were insufficient in terms of a pedogenesis with special features in relief and sediments.
