Three hypotheses were tested relating to Wyoming big sagebrush (Artemisia tridentata Nutt. ssp. wyomingensis (Beetle and Young) revegetation on coal-mined land in Wyoming: (1) that fourwing saltbush (Atriplex canescens (Pursh) Nutt.) seeded > 2.2 kg pure live seed (pls)/ha would exclude sagebrush, (2) the contrasting view that the saltbush, as a "pioneer plant", facilitated sagebrush stand deve...

The importance of subsoil features for phosphorus (P) leaching is frequently mentioned, but subsoil effects are still poorly documented. This study examined whether the subsoil of four agricultural Swedish soils (two sand and two clay) functioned as a source or sink for P leaching by measuring P leaching from intact soil columns with topsoil (1.05 m deep) and without topsoil (0.77 m deep) over ...

Introduction: Uncontrolled and improper landfilling of solid waste increases the concentration of heavy metals in the soil. Therefore, this study aimed to investigate soil contamination with heavy metals in the landfill of municipal and hospital waste in Sabzevar city by compiling a map of the severity of heavy metal pollution in the soil. Materials and Methods: Concentrations of heavy metals ...

Abstract Intensified vehicular traffic causes increased heavy metal contamination of the environment. We investigated chemistry soils located under silver fir stands in vicinity Poland’s S7 roadway. Three sampling sites were central Poland. Fieldwork included soil organic (O) horizon and mineral (A) topsoil. analyzed pH, carbon (C) nitrogen (N) concentration, HCl-extractable forms sodium (Na) m...

The Spatial and temporal variability of soil properties (fluid composition, structure water content) hydrogeological employed for sustainable precision agriculture can be obtained from geoelectrical resistivity methods. For agricultural practices, site-specific information is paramount, especially at the planting season. An integrated one-dimensional (1D) two-dimensional (2D) electrical surveys...

Sir, We have read with interest the article by Spector et al. [1] which showed that higher blood levels of lead were associated with lower estimated glomerular filtration rate (eGFR) levels and impaired kidney function (eGFR < 60 mL/min/1.73m) in 3941 US adults participating in National Health and Nutrition Examination Survey (NHANES). This effect was particularly observed in subjects >60 years...

In most soils of the humid tropics, kaolinitic topsoil horizons overlie more gibbsitic horizons. This arrangement cannot be produced simply by leaching. Quantitative measurement of the turnover of chemical elements in the litterfall in an Amazonian ecosystem indicates that the forest cycles a significant amount of elements, particularly silicon. As a result, fluids that percolate through topsoi...

this paper deals with the planning of rehabilitation of spoils of asbestos mine in nw greece with the name mabe in prefecture of kozani. for this purpose a detailed ecological research has taken place in the wider area in order to estimate the prevailing environmental (site) conditions. the spoils heaps are characterized by very steep slope inclination (80-90%). in order to improve the stabilit...

Due to rapid urbanization, urban lands have been expanded into existing agricultural areas. With such spatial changes, in the expanding cities or peri-urban areas are easily exposed contaminants generated by anthropogenic activities as traffic. Therefore, this study aimed investigate heavy metal concentrations major roadside soils distance medium-sized cities, Jinju and Changwon, identify influ...
