An Investigation of the Subsoil Component of a Constructed Mine Soil
… of this study was to identify and describe soil structural patterns and rooting behavior in a reclaimed mine soil. The soil chosen for this study consists of approximately 40 cm of topsoil (A horizon) material placed over approximately 150 cm of a blend of B horizon, mixed paleoloesses, …

The Influence of Soil Reconstruction Methods on Mineral Sands Mine Soil Properties
Significant deposits of heavy mineral sands (primarily ilmenite and zircon) are located in Virginia in Dinwiddie, Sussex and Greensville counties. Most deposits are located under prime farmland, and thus require intensive reclamation when mined. The objective of this study was to determine the …

Mine soil properties influencing white pine (Pinus atrobus L.) growth in Southwest Virginia
… (Pinus strobus L.) trees were used to identify minesoil, plant moisture, and foliar nutrient properties influencing white pine growth on reclaimed mine sites in southwest Virginia. PRESSAll (SAS Views, 1984) was used to determine relationships between soil properties and growth, soil properties …

The determination of surface mine soil erodibility factors for two soils in southern West Virginia
… hour “storms” to three replicated plots to determine surface mine soil erodibility factors for two distinctly different soils in southern West Virginia. Other variables included in the study were detailed soil descriptions for each site, initial and final soil moistures, plot rainfall …

Mine soil genesis and tall fescue nutrient status as a function of overburden type and cultural amendment
Natural soils in the Appalachian coal mining region occur on steep slopes and are often thin, rocky, acidic, and/or 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 …

EVALUATING MINE SOIL PREPARED BY SCRAPER PANS FOR HERBACEOUS PLANTS AND PINE SEEDLINGS AT AN EAST TEXAS LIGNITE SURFACE MINE
… million trees on its reclaimed lignite surface mine operations in Texas. For decades, the use of improved reclamation techniques on Luminant’s mined lands have resulted in over 31,160 ha reclaimed to forests, wildlife habitat, and pastures with productivity levels similar to those found on …

Restoration of nitrogen and carbon cycling in an Appalachian mine spoil
… terrestrial ecosystems are largely lacking in mine soils. Reliable guidelines for effective long-term restoration require a detailed understanding of the ecological processes occurring within the mine-soil system. The objective of this study was to determine the extent to which inorganic N …

Dynamics and Characterization of Soil Organic Matter on Mine Soils 16 Years after Amendment with Topsoil, Sawdust, and Sewage Sludge
… present state and future prospect of the world's soil resources has prompted scientists and researchers to address the issue of soil quality and sustainable land management. Soil quality research has focused on intensively-managed agricultural and forest soils, but the concept and importance of …

Stochastic dynamic optimization approach for revegetation of reclaimed mine soils under uncertain weather regime
… assist planners in making decisions concerning mine soil depths and soil mixture ratios required to achieve successful revegetation of mined lands at different probability levels of success, subject to an uncertain weather regime. A perennial grass growth model was modified and validated for …

Long-Term Effects of Rock Type, Weathering and Amendments on Southwest Virginia Mine Soils
… of spoil type and amendments on Appalachian mine soil properties over time. The Controlled Overburden Placement Experiment was installed in 1982 in two parts, the Rock Mix (RM) Experiment compares mixes of sandstone (SS) and siltstone (SiS) spoils while the Surface Amendment (SA) Experiment …

Analysis of Reconstructed Mine Soils on Reclaimed Coal and Mineral Sands Mined Lands in Virginia
… land use potentials are greatly influenced by mine soil properties. I analyzed and classified coal mine soils in SW VA and mineral sands mine soils in SE VA to aid development of appropriate post-mining land use interpretations. For coal mine soils, long-term pedogenesis was assessed in …

Site Quality Classification for Mapping Forest Productivity Potential on Mine Soils in the Appalachian Coalfield Region
… and growth are dependent on many reclaimed mine land properties. However, conventional mapping techniques using USDA soil series does not identify these critical soil property differences. This study was conducted to create a forest site quality classification system to be used to evaluate …

Effect of land application of fluidized-bed combustion residue on soil and plant characteristics of reclaimed surface-mined pastures, performance and mineral status of grazing steers and nutrient balance by sheep fed the forage
… A grazing trial was conducted on an acidic mine soil to compare FBCR to dolomitic limestone and no amendment (control). Six steers per treatment were grazed rotationally on three replications (rep) of three .8 ha pastures. Both materials increased soil pH similarly, and reduced plant uptake …

Restoration of Prime Farmland Disturbed by Mineral Sand Mining in the Upper Coastal Plain of Virginia
Economic deposits of heavy mineral sand were identified in the late 1980's under prime farmland along the Upper Coastal Plain of Virginia. Mining in Virginia will commence in 1997 on the Old Hickory Deposit in Dinwiddie/Sussex Counties. Experiments were established on two mine pits representing two …

Properties and Potentials of Coal Mine Soils in Southwest Virginia 29 Years After Establishment
… in southwestern Virginia, to estimate long-term mine soil C sequestration potentials and nutrient capitals after different reclamation strategies. The COPE includes two studies, a rock mix study (RM) comparing topsoil substitutes created from different ratios of local overburden [pure sandstone …

Opportunities for improved surface mine reclamation in the central Appalachian coal region
… success of research efforts to develop improved mine soil construction and revegetation techniques, the majority of the mining and reclamation activities in the Virginia coal region are carried out using conventional methods: reconstructing steeply sloping mining areas to their approximate …

Managing symbiotically-fixed nitrogen on mined land for tree crops
Young mine soils constructed following surface-mining for coal contain low levels of organic matter and nitrogen. It was hypothesized that nitrogen-fixing plants could be incorporated into a reforestation system in a manner that would meet the short term and long-term nitrogen needs of crop trees …

Biogeochemical effects of an invasive grass across a land-use gradient: linking alterations of nitrogen cycling to depleted soil carbon pools
… effects of the invasive grass, Microstegium vimineum, to determine 1) whether a common plant-soil feedback involving alterations of nitrogen (N) cycling is linked to declines in soil carbon (C) stocks and 2) whether this mechanism explains variability in the invader’s impacts on soil C across a …

SIMULATED MINE LAND RECLAMATION IMPACT ON BIOMASS PARTITIONING AND NUTRIENT CONTENTS IN LOBLOLLY PINE
<p>Forest productivity on reclaimed mine land is hindered by soil compaction. Different techniques have been used to alleviate the effect of compaction to various degrees of success. The Forestry Reclamation Approach (FRA) was developed in the Appalachians and has been used to improve forest …
