AbstractSimultaneous uptake of Cd(II) and Pb(II) by corn in two artificially contaminated soils (sandy and sandy loam) amended withtwo doses of natural (NM) and modified (MM) montmorillonite were investigated in a pot experiment under greenhouseconditions. Results showed that the addition of NM and MM to sandy loam soils didn’t have significant effect on the uptake ofCd(II) by roots, then is translocated to the aerial tissues. On the contrary, uptake of Cd(II) by shoots was increased in potscont...

AbstractFactors influencing the distribution of Origanum onites L., (locally known as Turkish oregano) were analyzed on the LakesDistrict of Turkey, using Two-tailed Wilcoxon’s runk sum statistics and Pearson chi-square χ2 test contained in the SPSS 17.0package. An inter-specific correlation analysis (ICA) was also applied to determine indicator plant species of O. onites. Analysesperformed on environmental factors showed that there is a relatively high correlation between the occurance of ...

Abstract Wind erosion, which strongly affects both plant and soil development in arid environments, is dependent on soil properties, wind characteristics and plant cover. In a semiarid zone in SE Spain, a new technique consisting of dusting plants with a forced wind stream reduces tillage and significantly increases productivity. By using a blower once a year, dust is raised and partly retained by plants, and eventually ends up in the understory. To assess the influence of this technique on ...

As part of the 2012 Land Use/Land Cover Area Frame Survey (LUCAS), topsoil samples were collected in Bulgaria and Romania using the same methodology as for other EU Member States in an equivalent survey carried out in 2009. In total, 664 Bulgarian and 1384 Romanian samples were collected which enabled a comparative assessment of topsoil properties under different land covers within, and between, these countries, as well as in a broader European context. The samples were analysed for basic soil p...

According to literature, aggregate stability of soils is influenced by: particle size and soil texture, soil structure, content of Ca2+ and Mg2+, mineral clay type, soil content of organic matter, soil processing degree. This paper aims to investigate the influence of some physical, microbiological and chemical properties of saline soil concerning water-stable aggregate. The hydro system stability of the aggregates appears in the specialized studies as having a positive correlation with microorg...

To evaluate the effects of seasonal fluctuations, soil types, land use and management inputs on the abundance and composition of soil bacteria, twenty soils types from Moldavia region located in north-eastern Romania were compared. Changes in soil microbiota are an early and sensitive indicator of soil pollution and can be used to predict long-term trends in soil quality. The use of microbial properties as indicator of soil pollution is easily measured and can also be measured accurately across ...

Geocomposite materials consisting of lightly cemented mixtures of expanded polystyrene beads (EPS) and backfill soils are commonly used as fillers and for the construction of light weight embankments. The constant normal stress (CNS) and constant volume (CV) direct shear parameters as well as the relationship between gradation properties of four residual granular backfill soils and direct shear parameters of lightly cemented mixture of EPS and backfill soils was evaluated. The maximum density an...

This paper presents the results of experimental researches regarding the optimization of a decontamination process through thermal desorption of soils contaminated with crude oil. The optimization was performed for the following desorption parameters: heating temperature of the soil and the treatment duration, by increasing the temperature from 300°C to 350°C and decreasing the treatment duration from 10, 15 and 20 minutes to 5, 10 and 15 minutes. The economic calculation of the decontam...

Water retention capacity and hydraulic conductivity are major soil hydraulic properties that influence soil quality and the environment. The objective of this work was to assess major soil hydraulic characteristics in response to the effect of soil management and tillage practices. Eight soil treatments were considered: conventional tillage, reduced tillage, no-tillage, fallow notillage, abandoned soil, compacted soil, plough on compacted soil, and application of super absorbent polymers. The...
