Lignite fly ash (LFA), being alkaline and endowed with excellent pozzolanic properties, a silt loam texture, and plant nutrients, has the potential to improve soil quality and productivity. Long-term field trials with groundnut, maize, and sun hemp were carried out to study the effect of LFA on growth and yield. Before crop I was sown, LFA was applied at various doses with and without press mud (an organic waste from the sugar industry, used as an amendment and source of nutrients). LFA with… 
A comparative study on field scale demonstration of fly ash and pond ash for cultivation of maize-groundnut crops in sequence on a wasteland
ABSTRACT In India, the major source of energy is thermal power plants that contribute about 70% of the total energy requirement and produce a huge amount of fly ash per year. The fly ash and pond ash
A field trial was set up at Gomal University Research Farm , Dera Ismail Khan, Pakistan during 20072008 to asses the impact of pressmud on lentil yield and yield components. Four replicates of 8
Utilization of fly ash - bottom ash, compost and arbuscular mycorrhizal fungi on growth of crops
This study examines the effectiveness of fly ash-bottom ash (FABA) from Suge Steam Power Station, Belitung Island, Indonesia. FABA will formulated with compost and arbuscular mycorrhizal fungi (AMF),
Enhanced Plant Restoration in Open-Pit Mines Using Maize Straw and Ultrasonically Pre-Treated Coal Fly Ash
The rehabilitation of the post-mining landscape is one of the intractable bottlenecks faced by the mining industry. Though plant restoration has been regarded as an efficient way, its application is
Studies on Growth and Yield Response of Jatropha curcas Plant on Fly Ash Amended Soil
ABSTRACT Fly Ash (FA) is usually considered unfavorable to plant growth and its disposal has become a serious environmental issue. However, some studies on revegetation on fly ash dumps showed some
Impact of high rates of coal flyash on some pertinent soil characteristics and sugar cane yield in Mauritius.
THE COMBUSTION of coal for cogeneration of electricity by the sugarcane industry in Mauritius generates annually some 20 000 tonnes of ash that need to be disposed of in an environmentally sound
Impact of Fly Ash Application on Trace Metal Contents in Some Root Crops
Abstract Fly ash, a solid waste being generated during power generation in thermal power plants, contains most of the plant nutrients in sufficient quantities, which holds great promise for its bulk


Evaluation of fly ash as a soil amendment for the Atlantic Coastal Plain: II. Soil chemical properties and crop growth
Crop yields in the Atlantic Coastal Plain of the U.S.A. are limited by the low moisture-holding capacities of the sandy soils common to the region. Corn was grown in a Hammonton loamy sand soil
The Production of Artificial Soil Mix from Coal Fly Ash and Sewage Sludge
The scarcity of land in Hong Kong makes landfilling an unattractive means for the disposal of sewage sludge and coal fly ash. Therefore, reutilisation of these solid wastes might ease the disposal
Effects of High Rates of Coal Fly Ash on Soil, Turfgrass, and Groundwater Quality
A field study (1993–1996) assessed the effects of applying unusually high rates of coal fly ash as a soil additive forthe turf culture of centipedegrass (Eremochloa ophiroides).In addition, the
Effect of fly ash on physico-chemical properties and nutrient status of soil
The effect of varying levels of fly ash (FA) on pH, electrical conductivity (EC), and available major plant nutrients such as nitrogen, phosphorus and potassium (NPK) was investigated in an alkaline
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,
Effect of coal fly ash and co‐composted sewage sludge on emergence and early growth of cover crops
Abstract Fly ash, a by‐product of coal combustion, is often stored in landfills. Stabilization of fly ash deposits can be hindered by phytotoxic levels of B and soluble salts in the ash. Two
Physico-chemical characterization of water extracts of different coal fly ashes and fly ash-amended composts
The pH, conductivity and the concentration of 15 selected elements were measured in the water extracts of five coal fly ash samples collected from Savannah River Site (SRS) and one from South
