This document proposes changes to the World Reference Base for Soil Resources (WRB) to better acommodate soils dominated by technic material. It is the second draft, aiming at the revision of the WRB to be submitted at the 2006 International Union of Soil Sciences (IUSS) meetings. Three new definitions are proposed: – Artifacts are defined as solid or liquid material created by humans as part o...

Background, Aims, and Scope. Historically, built areas were ignored in soil mapping and in studies of soil formation and behaviour. It is now recognized that these areas, and therefore their soils, are of prime importance to human populations. Another trend is the large increase in reclaimed lands and new uses for old industrial areas. In several countries there are active projects to map such ...

During opencast lignite mining, the natural landscape is damaged, along with soils, and new anthropogenic landforms are created which require reclamation. Usually, evaluation of effects reclamation (mostly forestry) concerned changes in chemical properties first years, mainly surface horizon. This study analyzed effect long-term agricultural (43 years) on physical water retention Technosols. Th...

In this work the adsorption and immobilization of copper ions four different Technosols constructed with wastes were tested. These soils made from mixtures limestone wastes, organic matter, sand, bentonite. The methods used “batch” columns experiments, where in contact a Copper (Cu) rich solution for 24 h afterwards 24-weeks. Total concentration adsorbed Cu, sequential extraction Cu leachates e...

Organic compounds resulting from the decomposition of organic amendments are used in the remediation of trace element (TE) contaminated soils. The mobility, phytoavailability and soil exposure intensity of molybdenum (Mo), chromium (Cr), zinc (Zn), copper (Cu), Cobalt (Co) and Arsenic (As) were evaluated in the phytoremediation of contaminated technosols after the addition of two organic matter...

in this study, micromorphological properties of some samples collected from pedons polluted with petroleum refinery wastes and some adjacent unpolluted pedons were studied. after description of the studied pedons, disturbed and undisturbed samples were collected for physicochemical and micromorphological analyses. the results showed that the physicochemical properties (i.e. structure, bulk dens...

Reflectance spectroscopy in the visible-infrared and shortwave infrared (450–2500 nm) wavelength region is a rapid, cost-effective non-destructive method that can be used to monitor heavy metal (PTE, potential toxic elements) contaminated areas. Due PTE pollution has accumulated course of wastewater treatment, existence Technosols presents an environmental problem, source for uptake by vegetati...
