Impact of the low and high concentrations of fly ash amended soil on growth, physiological response, and yield of pumpkin (Cucurbita moschata Duch. Ex Poiret L.)

Coal fly ash and nitrogen application as eco-friendly approaches for modulating the growth, yield, and biochemical constituents of radish plants

“…Today, improving the agronomic features of soils for greater agricultural yield has become a serious problem for researchers in order to meet the demand for rapidly rising populations. Because it contains Si, Al, Fe, Ca, Mg, K, P, Cu, certain other micronutrients, and a low amount of C, fly ash has the ability to boost the fertility of agricultural soils based on the pore space ( Ahmed et al, 2021 ). Absolute hollow silt-sized particles supply water molecules on a larger scale ( Skousen et al, 2013 ).…”

“…Absolute hollow silt-sized particles supply water molecules on a larger scale ( Skousen et al, 2013 ). EDX profiling of FA indicated that it contains valuable plant nutrients and caused enhancements in water holding capacity, porosity, pH, organic substances, and soil permeability ( Haris et al, 2019 , Ahmad et al, 2021 ).…”

“…Because of their exorbitant pricing, the majority of small-scale farmers are unable to purchase them. It is also critical to utilize contaminants to minimize global pollution like fly ash (FA), which is among the most crucial forms of particulate waste produced by the burning of coal combustion for the generation of energy ( Ahmed et al, 2021 ).…”

“…The constant and huge manufacturing of FA necessitates a variety of dumpsites. FA is regarded as a significant environmental danger around the world due to its negative effects on the environment ( Ahmed et al, 2021 ). Heavy metals such as Pb, Cr, Fe, Mn, Ni, Zn, or As found in significant quantities in FA may have a detrimental impact on plant development.…”

Applicability of Ash Wastes for Reducing Trace Element Content in Zea mays L. Grown in Eco-Diesel Contaminated Soil

“…For the most part, fly ash is used as a substitute for mineral fertilizers to improve the physical, chemical, and biological properties of soils [ 31 , 51 , 52 ]. It is also used as an ameliorant and yield enhancer [ 36 , 53 , 54 ] and a potential means of reducing trace element accumulation in plants [ 55 ].…”
