Abstract This study investigated vegetation strategies for a fly ash landfill in a semi-arid environment. Ten plant species adapted to the local climate were initially evaluated for their germination characteristics in various mixtures of Tivoli fine sand, fly ash, and cattle manure. Alkali sacaton (native, Sporobolus airoides (Torr.) Torr.), blue grama (native, Bouteloua gracilis (H.B.K.) Lag. Ex Griffiths), a forage sorghum (variety Canex, Sorghum bicolor (L.) Moench), sand bluestem (variety…

Influence of fly ash mixtures on early tree growth and physicochemical properties of soil in semi-arid tropical Alfisols

The beneficial effects of planting mixtures comprising of fly ash at the rate of 66%, 33% and 17% by soil volume were assessed for the early growth of two economic tree species, teak (Tectona

Meadow species in the early stages of succession on the ash settler of power plant EDF Toruń SA in Toruń, Poland

The results demonstrate that meadow species as Festuca arundinacea , Festuca rubra , Lolium perenne , Poa annua, Rumex acetosa and Taraxacum officinale, Poa trivialis and Viccia cracca can be helpful in restoration of fly-ash landfills.

The Effects of Neem Wood Ash on Soil Characteristics and Seedling Growth of Cowpea (Vigna unguiculata L. Walp)

Wood ash treatment affected physical and chemical poperies of soil which in turn results decreased seedling growth performance of cow pea.

Ecological restoration of fly‐ash disposal areas: Challenges and opportunities

Fly‐ash (FA) is a by‐product or residue that is produced during the combustion of coal for energy production in thermal power plants. The huge amount of FA generation is a global problem; and coal



Evaluation of Revegetation Techniques of a Saline Flue Gas Desulfurization Sludge Pond

Codisposal of flue gas desulfurization (FGD) sludge with low-volume generating station waste simplifies disposal but creates a saline, high-boron (B) waste that may be difficult to revegetate after

Influence of fly ash on soil physical properties and turfgrass establishment.

Ash treatment did not significantly influence water infiltration rate, bulk density, or temperature of the soil, but substantially improved water-holding capacity (WHC) and plant-available water (PAW).

Impact of Fly Ash Amendment and Incorporation Method on Hydraulic Properties of a Sandy Soil

Coal fly ash has physical and chemical characteristics that makeit useful as a soil amendment, one of the more important beingthe potential to permanently improve the soil water relations ofsandy,

Soil solution chemistry of a fly ash-, poultry litter-, and sewage sludge-amended soil.

Mixing coal fly ash (FA) with organic wastes to provide balanced soil amendments offers a potential viable use of this industrial by-product. When such materials are land-applied to supply nutrients

Erodibility of fly ash used as a topsoil substitute in mineland reclamation

Fly ash, a by-product of coal-fired power plants, has been used successfully in reclaiming abandoned mine lands by improving mine-soil chemical and physical properties. However, the fine sand-silt

Evaluation of fly ash as a soil amendment for the Atlantic Coastal Plain: I. Soil hydraulic properties and elemental leaching

A major limitation to crop yields in the Atlantic Coastal Plain is drought stress caused by the low moisture-holding capacities of the coarse-textured soils common to the area. Because coal fly ash

Abstract A greenhouse study was conducted to assess the use of a sewage sludge/fly ash mixture in soils for increased growth and uptake of nutrients by Sorghum vulgaris var. sudanense Hitchc.

Utilization and Disposal of Fly Ash and Other Coal Residues in Terrestrial Ecosystems: A Review

Impacts of land-oriented utilization and disposal of various coal combustion residues are summarized. The physical and chemical properties of coal ashes are dependent on the coal's geological origin,
