“…Such type of 'anthropogenic soils' has received most attention and some names have been suggested [15] - [16] - [17] - [18] - [19]. In the WRB these soils were not retained as Anthrosols because of they have not been subjected, for a sufficiently period of time, to pedogenetic processes.…”

-In recent decades man's role in soil formation has become a matter of great concern among soil scientists. Man is now considered a soil-forming factor and anthrosolization is recognised as a soil-forming process that consists of a collection of geomorphic and pedological processes resulting from human activities. These human activities include deep working, intensive fertilization, the addition of extraneous materials, irrigation with sediment-rich waters and wet cultivation. In this paper we review the influence of man as a soil forming factor stressing also some peculiar aspects linked to their classification.

“…Toomanian et al (2003) focused on gypsiferous soils in Central Iran and argued that the WRB seems to be the most appropriate system for the classification of these soils. Dazzi et al (2009) proposed a new diagnostic horizon for Anthrosols in WRB as a "geomiscic" horizon which can be succinctly defined as a horizon that develops when a layer of at least 30 cm thick and of different kinds of earthy materials is added to the soil using earthmoving equipment. Charzyński et al (2013) proposed that new qualifiers of Edific, Nekric, Misceric, Artefactic, Radioactivic and new specifier of Technic be added to Technosols in WRB.…”

Abstract. The two most widely used soil classifications are the Soil Taxonomy (ST) and the World Reference Base for Soil Resources (WRB). The purpose of this paper is to clarify the differences and the similarities between ST and WRB in their current state, with some examples for representative soils in arid and semi-arid regions of Iran. Four representative pedons were classified and soil units from WRB were compared to those obtained by using ST at the family level. WRB could show the status of soils polluted by heavy metals through the Toxic qualifier and its subqualifiers. On the other hand, ST could indicate the status of shallow soils in our studied soils but it was not able to show gleyic conditions and the existence of a salic horizon because of the differences in its criteria compared to those of WRB. Special effort should be made to quantify various anthropogenic activities in upcoming editions of both classification systems.

“…The term pedotechnique (Fanning and Balluff Fanning, 1989), indicates all those anthropogenic activities, that since 1980 have seen a growing influence of man on pedogenesis and on soilscapes (as for example in agriculture management, or for waste disposal, or in mining operations, etc. ), both by the selection and evaluation of suitable materials for the "construction" of soils, or by the use of appropriate procedures to modify the characteristics of the soil, till the construction of soils for specific purposes, such as happens in large scale farming (Dazzi and Monteleone, 2007;Dazzi et al, 2009;Lo Papa et al, 2011).…”

a b s t r a c t a r t i c l e i n f oTechnosols are soils developed on non-traditional substrates and containing large quantities of materials mostly due to intensive human industrial activity, such as artefacts. The increasing number of sites affected by Technosols and their impact on the environment as growing media for plants or as source of pollutants require an understanding of their functioning and evolution, above all the knowledge on the transport of toxic substances from contaminated technogenic soils to groundwater. A case study on properties, remediation and evaluation of Technosols made up by vitrified fly ash and glass-ceramics in Italy was carried out. Original technogenic soils, classified as Spolic Technosols (ecotoxic), were pedotechnically in situ remediated by adding smectitic marlstone and Ca(OH) 2 . Chemical analysis on samples from piezometers showed the presence of harmful heavy metals in groundwater. By means of boreholes and soil profiles the new soils generated, after remediation, were physically and chemically characterized and classified as Spolic Technosols (calcaric). Analysis on soil toxicity and leaching tests showed the effectiveness of the remediation and the mobility reduction of some potentially harmful elements according to the environmental Italian regulation.
