Surface mining in Appalachia disrupts large areas of forested land. Federal and state laws require disturbed lands be reclaimed by re-constructing the landscape and replacing soil materials to provide a rooting medium. If insufficient quantities of native topsoil are available, substitute materials derived from the overburden may be used as soil media. This study examined soil and foliar nutrie...

Metals are ubiquitous within the earth crust. However, the exceptional high-level concentration of heavy metals in the soil due to natural or anthropogenic activities and the chemical forms in which they exist determine the level of risk they portend to the environment. This work was aimed at determining the background level of the presence of seven priority toxic metals (Cr, Ni, Pb, As, Cd, Cu...

Tree water uptake relies on well-developed root systems. However, mine wastes can restrict root growth, in particular metalliferous mill tailings, which consist of the finely crushed ore that remains after valuable metals are removed. Thus, water stress could limit plantation success in reclaimed mine lands. This study evaluates the effect of substrates varying in quality (topsoil, overburden, ...

The concentrations of potentially toxic elements (PTEs) in the topsoils Udachny mining area were determined. soil samples taken from 42 topsoil at a depth 0-20 cm. PTEs (Pb, Cd, Cr, Zn) analyzed by atomic absorption method on MGA-1000. In addition, pH and organic matter (humus) measured for each sample. potential ecological risk was quantitatively estimated site. most severe contamination study...

This study aims to analyze the process of soil formation on overburden material in reclamation area 2013 (9 years), 2015 (7 and 2018 (4 years) support success sustainable reclamation, relationship between planting age, morphology climate conditions that can affect overburden. The research was conducted at a coal mining company located Tanah Bumbu Regency, South Kalimantan Province. method used ...

The grain size composition of topsoil characterizes the soil texture and other physical properties. The coarsening of topsoil grain size is a visible symbol of land degradation; thereby the change in topsoil grain size can be potentially used to monitor desertification using remote sensing. This study proposes a new index for detecting topsoil grain size composition through ground in situ soil ...
