Mine soil genesis and tall fescue nutrient status as a function of overburden type and cultural amendment
… infertile. This often makes use of natural topsoil for surface coal mine reclamation impractical. Sandstone (SS) and siltstone (SiS) topsoil substitute materials in mixed and pure treatments were compared to ascertain their effects on soil genesis and tall fescue (Festuca arundinaceae …

Organic amendment effects on carbon and nitrogen mineralization in an Appalachian minesoil
The use of blasted rock overburden as a topsoil substitute during surface-mined land reclamation is practiced in areas with thin, unrecoverable topsoil. The long-term productivity of topsoil substitutes has often been difficult to maintain under forage and row crops. The objective of this project …

Reclamation of surface-mined forest land in the southern Appalachians
… that the type of overburden material used as a topsoil substitute can have long-term effects on tree growth. After five years, average tree volume in a sandstone spoil was five times greater than tree volume in a siltstone spoil. In the southern Appalachians, oxidized (brown) sandstone is a good …

Properties and Potentials of Coal Mine Soils in Southwest Virginia 29 Years After Establishment
… two studies, a rock mix study (RM) comparing topsoil substitutes created from different ratios of local overburden [pure sandstone (SS), pure siltstone (SiS), 2:1 SS to SiS, 1:1 SS to SiS, and 1:2 SS to SiS], and a surface amendment study (SA) comparing organic amendments [control (CON), …

Long-Term Effects of Rock Type, Weathering and Amendments on Southwest Virginia Mine Soils
… control (CON), sawdust (SD at 112 Mg ha⁻¹), topsoil (TSâ 15 cm), and biosolids (BS) at 22, 56, 112 & 224 Mg ha⁻¹. Both experiments were sampled in 2008 and compared with historical data. After 26 years, all RM treatments had higher silt+clay and decreased sand. Mine soil pH and electrical …
