2007 m. Nr. 3 Development, properties and classification of dune soils
in the Curonian Spit National Park, Russian part
Especially for the Russian part of the Curonian Spit detailed descriptions of dune-soils are lacking.
The present work focuses on an ecological soil characterisation carried out across a well-dated sand-dune chronosequence. The soil development is characterised by a fast decalcification combined with a rapid decrease of soil pH and an increase of organic matter and cation exchange capacity with increasing soil age and vegetation cover. Following the international WRB classification (FAO, 2006), the examined soils can be classified as Calcaric Arenosol, Dystric Arenosol, Hyperdystric Arenosol, Protic Arenesol, Dystric Gleysol and Haplic Podzol. It is possible to distinguish three different soil development stages associated with respective stages of plant succession: Initial (Calcaric, Protic and Dystric Arenosol), intermediate (Hyperdystric Arenosol) and mature (Haplic Podzol) soils. Keywords: arenosols, soil development, soil classification, pedogenesis, podzol, migrating dunes, coastal ecology, the Curonian Spit |
