Classification of technogenic soils according to WRB system in the light of Polish experiences

Abstract

Abstract Technosols are relatively young soil group in WRB soil system, and there is still a lot of to do to better understand processes taking place in these soils and to classify them in a proper way. The objectives of this paper were to (1) evaluate Technosol and 'technogenic' qualifiers for other Reference Soil Groups, and (2) propose new solutions which would improve the classification of technogenic soils in WRB. New qualifiers . Edific, Nekric, Misceric, Artefactic, Radioactivic and new specifier . Technic . are proposed to be added to keys to Technosols. Moreover, Salic and Sodic qualifiers should be also available for Technosols. Furthermore, the supplementation of definitions of thionic horizon and sulphidic material with reference to Technosols is also suggested
