Cambisols Classification in „Central Balkan” National Park

Analysis of the Cambisols classification on the territory of the Central Balkan National Park has been carried out. The assessment of the available information has revealed the insufficient level of knowledge and use of outdated criteria for soil definition. The presence of Dystric Cambisols, Eutric and Dystric Regosols, Haplic Umbrisols, Rendzic Leptosols, Haplic Fluvisols has been determined in separate studies. A detailed study is required in order to define the soils and update their classification. This will contribute to the proper planning of the necessary measures for soil protection for the different types of land use.
