“…Roots of S. munja have been found to grow up to 10-15 ft deep in FA (Pandey et al, 2012). Various other aromatic grasses like Cymbopogon martinii, Vetiveria zizanioides, Cymbopogon flexuosus and Cymbopogon winterianus can also be grown extensively on FA deposits to earn profits (Verma et al, 2014). Very few studies have been done in past on the growth of these grasses on FA except some reports which studied the growth pattern with high rate application of FYM (Kumar and Patra, 2012).…”

Abstract. Uninterrupted generation of fly ash by the coal based thermal power plants and its dumping has lead to steady encroachment of useful land in India. The deleterious effects of fly ash on the nearby environment are inevitable due to its fine texture and presence of toxic metals. Thus, proper revegetation programme of the sites are highly desirable due to their continuance in being the part of landscape. This paper conglomerates all the issues which should be taken into account to prevent groundwater contamination and increase phytostabilization of metals. An insight to the past and the prevailing restoration scenario will help in selecting of plant species for biomass production. Primarily, an integrated approach towards revegetation is necessary which comprises native and exotic grass-legume species, readily available composts, green manure, and mulches. The paucity of studies in relation to the long term changes in fly ash due to vegetation is to be permeated through regular analysis of substrate nutrient status, extent of nutrient loss, bioavailable toxic metals, in restoration sites. The range of methodologies and indexes discussed here will benefit the future management approaches of fly ash with emphasis on phytoremediation of trace metals, development of aesthetically pleasant landscape and productivity.

“…It has been observed that soils which are located in the vicinity of coal-fi red thermal power stations are polluted not only by ashes but also by heavy metals including arsenic, nickel, strontium, chromium, copper, cobalt, mercury, cadmium, barium, beryllium, and vanadium (George et al 2015 ). Residues of coal combustion are considered as hazardous solid waste around the globe (Verma et al 2014 ).…”

“…high valuable economic crop, no or least risk of contaminant in use of end products, unusual character profile of the crop) for the selection of aromatic plants for remediation and management of arseniccontaminated soil sites. The cultivation of non-edible economic aromatic crops has often been suggested as a profitable and a feasible option for avoiding contaminants' entry into the food chain (Lal et al, 2008a,b;Verma et al, 2014). The global demand of essential oils from aromatic grasses is continuously increasing and it is expected to reach the mark of US$ 5 trillion by the end of year 2050 (Verma et al, 2014).…”
