This study reports the assessment of the pollution to urban soil pollution in few major cities of Romania. In the past few years, in all over Romania an increasing trend could be noticed related to the scientific interest for soil contamination due to anthropogenic activities. Nevertheless, a research aiming to assess a quality screening report related to the presence of contaminants in top soils of urban areas due has never been conducted and the public society is deprived of such information in all cities. The a...

A detailed analysis of a soil chronosequence located in well drained upland positions within broadleaf subzone of the Russian plain was performed to investigate the possible transformation of pedogenic pathways related to the climatic changes during the Late Holocene. The soil chronosequence included a soil buried under fortification (earthen) wall constructed in Early Iron Age and a day surface soil developing under natural (broadleaf forest) vegetation. Different pedogenic processes were evaluated using a number...

The paper presents a description of materials and available data as well as research methods which permitted the development of a complex data base allowing for the analysis of the spatial variability of soil properties in Poland. A data base was developed for the Czermin commune with the application of data on soils available in the State Surveying and Cartographic Resource database. Field and laboratory research were carried out, as well as spatial analyses. They provided the basis for the preparation of a map o...

Carrot culture is highly dependent on soil, silty-clay or silty soils with high permeability and free of weeds are preferred. Weed control is a very important part of the production technology for plants. Chemical weed control has been found to have some advantages of which we mention: it is less labor-intensive, increases productivity, reduces the number of passes on farmland and increases production. The main purpose of this paper was to provide the most efficient solution for weeds control in carrot crops, usin...

The soils in the study area Zemianske Kostolany were polluted with fly ash material after dam failure of the coal-ash pond (1965). Fly ash represents possible source of potentially toxic elements, because meteoric water or groundwater may percolate through and interact with the ash materials in soils, producing leachates that contain elevated levels of trace elements, in our case, arsenic. The main objective of this study was to assess the potential of arsenic releas e into the environment. Amount of released arse...

Organic contaminants such as total pe troleum hydrocarbons, including aliphatic hydrocarbons, polycyclic aromatic hydrocarbon s and BTEX are recognized as one of the predominant pollutants within Romanian contaminated sites. This study presents a set of experiments for the remediation of a soil contaminated accidentally with petroleum products conducted in slurry-type batch systems, designed to establish the best remediation approach. The experime ntal variants consisted in biological remediation (natural attenuat...

Repeated application of phosphorus (P) fert ilizer in soils, in excess of crop removal rates, may increase the concentration of P in soil solution and conse quently the transfer of soluble P to streams. Excess P in natura l aquatic systems can promote eutrophication of lakes and rivers. The application of calcareous sorbent in the adsorptive removal of P from soil solution could be a suitable technique. The objective of the experiment is to evaluate the sorption of P in a marginal coarse-textured soil (pH 5.5) ame...

The phytoavailability of aluminum (Al) in Al-ri ch acid podzolic soils is of particular concern in many Quebec agricultural areas due to its toxic effect on plant growth. Liming materials may mitigate Al phytoavaila bility and toxicity depending on Al pool and plant part, respectively. Our objective was to determ ine the effect of dolomitic limestone on the distribution of Al species in soil and to evaluate the uptake and distribution of Al in the different parts of maize ( Zea mays L.). Maize was grown in 40- cm ...

The research of restoration applicability of dump rocks started about 25 years ago. However, the complex geological, pedological and hydrogeological evaluation and the evaluation of zoocoenoses of dump areas has not been elaborated yet. It is the main topic of grant project started in 2009. Main results of this research are shown in this paper. Main attention is focused to the comparison between restorated areas and areas retained for natural succession in North Western Bohemia.
