Analysis of grains grown on fly ash treated soils

Effect of Combined Application of Bottom Ash and Compost on Heavy Metal Concentration and Enzyme Activities in Upland Soil

“…한 조사가 부족하였다 (Mittra et al, 2005;Patra et al, 2012). 일부 연구에서는 바닥재 내에 포함되어 있는 중금속의 식물이용성을 저감시키기 위하여 중금속을 흡착할 수 있는 하수슬러지와 혼합 시용하여 토양개량제로 활용하는 방안에 대해 조사하였다 (Lai et al, 1999).…”

Characterization of Fly Ash for its Mineralogy, Physical and Chemical properties – A Review

“…A study of coal and fly ash samples, using particle induced X-ray emission spectroscopic technique confirmed that K, Ca, Ti and Fe were present as major elements, whereas, other elements, e.g. V, Cr, Mn, Co, Ni, Cu, Zn, As, Se, Rb, Sr and Pb were present in trace amounts (Patra et al, 2012). (Franus et al, 2014).…”

Opportunities and challenges in the use of coal fly ash for soil improvements – A review

“…However, the bioavailability and leaching potential of CFA-borne PTEs may not increase significantly or may decrease with time especially in the cases of alkaline CFA due to the expected increase in soil pH (Kim et al, 1994;Tsadilas et al, 2002Tsadilas et al, , 2009b. Patra et al (2012b) indicated that CFA is a useful soil amendment which can improve the physical and chemical properties of nutrient deficient soils and thus improves the soil fertility and productivity. The risk of soil contamination with CFA-borne PTEs can be mitigated by controlled land application of CFA in terms of its amount and the concentration of PTEs.…”
