ResumoThis chapter discusses podozol and podzolic soils. The term podzol is applied to the bleached horizon that occurs near the surface of soils in the taiga zone. The word was by no means restricted to soils that were well drained. The appreciation of “illuviation” as an important feature of soils with bleached surface horizons led to the application of the word podzol and its derivatives to a wide variety of soils. The distinctions among many of these podzolic soils have never been clearly made, but two main groups of the better-drained varieties have been recognized: podzolic and sod-podzolic. On the basis of laboratory data, the sandy podzolic soils are similar to what are called podzols or humus-iron podzols. The podzolic soils of heavier texture and the sod-podzolic soils show a relatively uniform clay composition.
